Introduction 1

This manual is intended to serve as a single reference guide to AVANCE spec-trometers. It has been written primarily for service engineers, though some infor-mation may also prove useful to applications and sales personnel.

It is hoped that after reading this manual service engineers will be able to effec-tively troubleshoot an AVANCE type spectrometer. Little effort has been made toexplain the internal workings of the various boards and units. With the use of SMDtechnology these boards are not intended to be repaired in the field . Instead themanual concentrates on describing the board functions and specifications as wellas the relevant input and outputs.

Copies of this manual entitled "AVANCE Service Manual" are available from SAG( P/N Z31245, DWG-No. 915002)

RF Paths 2

Introduction 2.1

Tracing the rf paths is very often the first step in troubleshooting an instrument.Therefore before discussing the individual components of AVANCE spectrometersin detail, it may prove useful to give a brief introductory overview of the rf pathsand corresponding blanking/gating signals. For simplicity a relatively simple ex-ample of a two channel experiment will be used. All of the signals discussed in thefollowing sections are accessible and easy to measure.

RF paths in a DMX 2.2

Regardless of NUCLEUS or final frequency every rf channel begins with a 1Vpp3-4 MHz cw signal from the appropriate FCU (DDS out). Bit settings from the FCU(Connector F2) are then used to produce a PTS output frequency of SF01/02 +440 MHz. This cw signal is then transmitted to the SE451.

In the SE451:

1. The end frequency (SF01, SF02) is produced by mixing the rf input frequencywith 440MHz.

2. For the first time the rf signal is pulsed with the gating signals TGPCH1 andTGPCH2.

The pulsed rf signal is sent to the ASU which adjusts the amplitude according tothe attenuation set by software. FCU produced voltages called MOD and MULTare used to implement the fine amplitude adjustment. Fixed 20 and 40 dB attenu-ators may also be switched in using the FCU produced AT20 and AT40 signals.The max. output of the ASU is 1 Vpp corresponding to a software power level of pl= -6 dB.

Within the ASU the rf signal is blanked twice using the TGPCH and BPCH signalsfrom the TCU.


RF Paths

Figure 2.1. RF Paths in the DMX, OBS 13C DEC. 1H

The router inputs are hard-wired to the ASU outputs and the router outputs arehardwired to the power amplifier inputs. This means effectively that the router isused to connect each rf frequency with the appropriate amplifier. The routing iscontrolled with the TCU produced RSEL bits. Each router output is blanked by theBLKTR signals from the TCU.

After the router the linear amplifiers amplify the rf signal. No power regulationtakes place within the amplifiers, their output amplitude depends solely upon the rfinput amplitude. The amplifiers are also blanked using the BLKTR signals.

RF paths in a DMX

The final rf blanking takes place in the HPPR using the TGPPA signals. Note how-ever that whereas for all previously discussed blanking signals, the absence ofthe blanking signal would prevent rf transmission, in the HPPR the gating is re-quired for signals with amplitudes of <1 Vpp only. For all signals with greater am-plitude, the diodes in the HPPR would be forward biased by the rf itself. A secondblanking used to control the T>R switching in the HPPR OBS module uses theRGP.

The NMR signal from the sample is received in the SE451. The operation of theSE451 receiver module has not changed. Note however that

1. The RG bit settings are now set by the RCU and transmitted to the SE451 viathe HRD16 (or HADC).

2. The RGP (EP) signal is generated by the RCU and transmitted to the SE451via the HRD16 (or HADC).

3. The selection of the OBSERVE channel (H or X) is set by the TCU producedNMRWord 2 bit 11 (OBSCH1)

RF Paths

Pulse Names 2.3

All blanking/gating pulses used in AVANCE spectrometers are active low and pro-duced by the TCU. One of the features of the new ADVANCE range is that rf sig-nals are blanked more frequently than in previous spectrometers which shouldimprove the on/off ratio and give cleaner pulses with shorter rise and fall times. Alist of signals and corresponding abbreviations is contained in the Appendix. Oneof the initial problems is becoming familiar with the new terminology and the fol-lowing points will hopefully help clarify the situation.

What is the difference between a blanking pulse and a gatingpulse?Effectively none. When the signal goes low (active) rf power transmission is possi-ble. Gating signals are tied exactly to the rf pulse transmission. If a 7 µs rf signal isto be transmitted, than the gating pulse will go low for 7 µs at exactly the momentof transmission. This applies to the TGPCH signals used in ASU's and the SE451.

Blanking pulses are distinguished from gating pulses in that the timing is not nec-essarily tied exactly to rf power transmission. Instead the blanking pulse may goactive slightly prior to rf transmission and remain active for a short period aftertransmission. The optimal pre and post blanking timing will depend on the physi-cal properties of the various switches but are typically 1-3 µs and may be set us-ing the „edscon“ table (see "EDSCON: Edit spectrometer constants:" on page153)

Signal Name Connector Destination Connector Destination


Changes in the nomenclature:

In this respect the pulses BPCH (ASU) and BLKTR (Router and amplifiers) aretermed blanking pulses.

One inconsistency to this naming is the TGPPA signals used in the HPPR. Thetiming of these pulses may be altered with the „edscon“ table and they should re-ally be called blanking pulses as opposed to gating pulses.

Which pulse is assigned to which channelA specific rf channel“ number“ starts at the FCU and ends at the Router input.This rf channel connects FCU1 through the PTS and SE451/LOT to ASU Input1/Output1 to Router Input1. The corresponding pulses are TGPCH1 (SE451, ASU)and BPCH1 (ASU).

Similarly rf channel2 starts at FCU2 and ends at Router Input2 with correspondingpulses TGPCH2 and BPCH2.

Which BLKTR signal is used in the Router is determined solely by which Routeroutput is used. Thus an rf signal at RO1 is blanked BLKTR1, an rf signal at RO3 isblanked by BLKTR3 etc.

Since a particular rf channel number can be routed to several different Router out-puts, the BLKTR hardwired to the Router output can not be assigned the numberof the rf channel.

Since each Router output is hardwired to a particular amplifier the nomenclaturefor Router blanking and amplifier blanking is identical. Thus an amplifier whose in-put is taken from RO2 will be blanked by BLKTR2.

The various HPPR gating pulses are effectively hardwired to the TCU via the Pe-riph. Cascode and the pulses are assigned as follows:

The 2H module is gated by TGPPA1

The X-BB module is gated by TGPPA2

The 1H module is gated by TGPPA3

The USER-BOX module is gated by TGPPA4

Table 2.1. is a summary of the various gating/blanking pulses.

Changes in the nomenclature: 2.4

To try to make pulse terminology more meaningful (in English!) the following pulsenames are no longer standard

1. SPF (Sender Pulse) and SPFND pulses. These have been replaced by TG-PCH and BPCH respectively.

2. EP (Empfänger Pulse) is now called the RGP (Receiver Gating Pulse)

3. SPENAB is now called TGENAB

RF Paths in the DRX 2.5

The first major difference to the DMX is that the end frequency SF01, SF02 is pro-duced directly at the PTS output. There is no subsequent mixing with 440 MHz inan SE451 type device.


RF Paths

The LOT Board carries out the T/R switching on the OBSERVE channel (alwayschannel1 on DRX spectrometers). The output LT01 of the LOT Board will bepulsed with the RGP timing i.e. the signal will be missing during acquisition. Thesecond LOT output (LT02) will be cw.

The operation of the ASU, Router amplifiers and HPPR in DRX and DMX spec-trometers is identical.

The receiver used in the DRX is the RX22 which uses an LO of SF01 + 22 MHz asopposed to SF01 + 451MHz with the DMX.

RF Paths in the DPX 2.6

The operation of the FCU’s and PTS620 in the DRX and the DPX are identical.The first difference is in the LOT/ASU board which is effectively a combined ASUand LOT Board. The limitation of this arrangement is that the MOD module usedfor shaped pulses can not be fitted. The operation of the Router, amplifiers and re-ceiving section in DPX and DRX spectrometers is the same.

AQX32 Board Layout 3

Acquisition Bus 3.1

This is a real time Bus with interrupt capability. The Bus is designed to intercon-nect the TCU with the RCU and FCU's (and GCU where installed ).The TCU is theone and only master of the Acquisition Bus. In this way the TCU can have uninter-rupted control of the Acquisition timing.

The Bus has two sections. One is 16 bit, uni-directional real-time and used to con-trol the FCU's and RCU. The second is 8 bit, bi-directional non real-time and atpresent used exclusively to control the GCU.

Under certain circumstances (i.e. errors) the RCU or GCU can generate interruptsto the TCU.

The Acquisition Bus connection is made by plugging a Bus backplane onto theX32 backplane. The Bus backplane comes in two versions 8 slot (standard) or 5slot. The standard 8 slot Bus allows for one TCU (3 slots), one RCU, and 4 FCU's(or 3 FCU's and one GCU).

An 8 slot Bus can be easily combined with a 5 slot to give a 13 slot AcquisitionBus. Ribbon cable (P/N HZ2969) is used to connect the two Buses. When makingthis modification, the position of the terminating resistors must be changed (seeFigure 3.3.)

The extended 13 slot Bus allows for one TCU ( 3 slots), one RCU, one GCU and8 FCU's.

Board Order 3.1.1

Strictly speaking there is no set board order. However optimum performance isachieved with the TCU and a set of terminating resistors positioned at oppositeends of the Bus. This minimises unwanted reflections at the end of the Bus. TheRCU, GCU and FCU's can then be placed in any order in between.

With this in mind a standard layout has been decided upon for all 20 slot X32computers delivered with DRX and DMX spectrometers (see Figure 3.1.).TheTCU is placed at the extreme left end (front view) of the Acquisition Bus, the RCU(and terminating resistors) at the extreme right and FCU's and GCU and emptyslots in between.

As a result of thermal problems a slightly different layout has been used in the 9slot X32 as used in DPX spectrometers. The cooling fans are located to the left ofthe rack. To optimise the cooling of the FCU's and the TCU the board order in Figure 3.2. is now standard.


AQX32 Board Layout

Jumpers 3.1.2

There are no jumpers on the Acquisition Bus. Just remember to set the terminat-ing resistor networks correctly.

VME BUS 3.2

This standard bi-directional 32 bit Bus comes in two versions, 9 slot (DPX) and 20slot (DMX, DRX). It is used for communication between all boards in the AQX32rack including the CCU. On this Bus only the RCU and CCU can be master ( theRCU has priority over the CCU regarding Bus requests.)

The only requirement is that the CCU be placed at the extreme left (front view) ofthe Bus. This is to ensure that it receives all request messages.

Jumpers 3.2.1

To ensure that the DMA is not interrupted any vacant slots must have correspond-ing jumpers inserted at the backplane. If an extra new board is inserted the jump-ers must be removed from the backplane.

NOTE: The TCU consists of 2 boards but occupies 3 slots. The middle slotshould have the jumpers inserted.

TCU: Timing Control Unit 4

The TCU consists of two boards and occupies 3 slots in the AQX32 Rack. TheTCU delivered with the first batch of Avance instruments was officially known asTCU0 (TCU0 Main Board P/N H2558 and TCU Ext. Board P/N H2562). In Decem-ber 94 a new TCU_4K Main Board P/N H5811 was introduced. The main differ-ences between TCU0 and TCU_4K are

a) additional on board memory of 64kB instead of 8kB

b) the new TCU_4K hardware will support the BBIS system

c) the new TCU_4K requires XWIN-NMR software.

Pin assignments have not changed.

The TCU is connected to the FCU's, RCU and GCU where installed, via the Ac-quisition Bus. The TCU is the one and only master of this Bus.

Principal Functions 4.1

1. To synchronise and control the timing of the RCU, FCU's and GCU where in-stalled.

2. To generate gating and blanking pulses used in the ASU, Router, Amplifiersand HPPR.

3. To control the Router switching via the RSEL bit settings.

4. To generate various switching signals used in Amplifiers, SE451, QNP Pneu-matic Unit etc.

A complete list of the TCU outputs is given at the end of this Chapter. A singleTCU is designed to provide all the required signals for a spectrometer with up to 8rf channels.

All outputs of the TCU are TTL active low .The outputs are designed to go high af-ter a hardware reset of the CCU. Up to and including Layout C of the TCU MainBoard the required pull up resistors are however missing from the outputs of con-nector T4. As a result, after a reset, these outputs may be low when measuredwith the Burndy disconnected. This will be changed with future TCU layouts.

Physical Connections 4.2

1. SCSI connector T2 is connected directly to the Router and transmits the RSELbit settings as well as BLKTR1 - 10.


TCU: Timing Control Unit

2. TGPCH and BPCH signals are wired to the FCU F1 Adapter from where theyare connected to the ASU.

3. Connectors T3, T4 and T5 carry various signals to amplifiers, SE451 etc. viathe cable harness.

4. Connector T1 is used only for signals required for high power applications.

Note1: The signals TO/F and OBSCH1 are wired to the FCU in DPX spectrome-ters only. This is because they are required by the combined LOT/ASU Board. InDRX spectrometers the separate LOT Board receives these signals via the cableharness.

Note2: The four signals TGPCH1, BPCH1, TGPCH2, BPCH2 are the requiredgating/blanking signals for a single two channel ASU. For each subsequent chan-nel the corresponding pair of gating/blanking connections must be added. Kitswith correctly labeled cables are available for each extra channel that might beadded. When ordering it is important to specify which channel (e.g. 3 or 4 etc)which is to be added.

Note 3: The Burndy connectors T3,T4 and T5 are fitted exclusively with coaxpins. This means that it is not possible to use the traditional Burndy Break-outBox. Signals can however be easily checked at the other end of the coax cable.

The Burndy connectors are wired to the TCU via Ribbon connectors A and B i.eDC Pins on the TCU. The tables at the end of this Chapter give not only the CoaxPin assignments but also the corresponding DC Pin assignments of Ribbon con-nectors A and B..

The use of SCSI connectors as opposed to the traditional Burndy connectors hasthe following advantages.

a) Less space required

b) The use of twisted pairs reduces unwanted magnetic pickup because theenclosed area is small and the signals induced in successive twists tend tocancel.

TCU Power Supply 4.3

The TCU is powered from the Backplane and listed below are the relevant testpoints. You will need the Extension Board P/N H2066. to check the voltages.

Front Panel SMB Connectors 4.4

Two signals 40 MHz and AQS are daisy chained from the TCU to successive FCUboards (and GCU if fitted).

Table 4.1.

Voltage Current Test Point

+ 5V (digital) 8 A ST1: A32,B32,C32


Outputs

40 MHz: This output signal is TTL (3Vpp at 50 Ω ) and operates on a 50% duty cycle. Twooutputs are provided. One is used to clock the FCU's ( and GCU if fitted), the oth-er to clock the RCU.

RCUGO: This pulse is used to start the RCU and as such must accompany every scan. Thetiming is so that it goes high for 50 ns, approximately 200 ns before the RGP (EP)pulse.

AQS: Various instructions are sent from the TCU to the FCU's and GCU via the Acquisi-tion Bus. This TTL strobe pulse is used to synchronise the timing of the Bus.Thestrobe pulses go low for a minimum of 25 ns. The Data transfer itself is triggeredby the rising edge.

80 MHz.: This input signal comes directly from the PTS620 and is the clocking frequency forthe TCU. Note that the voltage level is 0 dBm ( 0.65Vpp at 50Ω ). This signal isused to generate the 40MHz signals described above.

TRIG0: This input is available should it be necessary to trigger the TCU with an externalinput.

TRIG 1: This input is for the signal "scantrigger" which originates in the BSMS.This signalcould be used to synchronise the TCU timing with sample spinning

Outputs 4.5

Total number of individual outputs: 147

Connector T1: 28 outputs: 2 inputs ( TRIG 2, TRIG3 )

Connector T2: 38 outputs

Connector T3: 32 outputs, 2 inputs ( TRIG 2, TRIG3 ) All Coax.

Connector T4: 34 outputs (All Coax).

Connector T5: 34 outputs (All Coax).

The inputs TRIG 2 and TRIG3 are not used at present. They could be usedshould it be necessary to trigger the TCU with an external input. Only one set ofinputs can be used either T1 or T3. Which are used is set with Jumpers W3 andW4 on the TCU Extension Board. The default factory settings are:

W3: Pin 2-Pin 3 => TRIG3 input is T3 Pin NN and T1 input not connected.

W4: Pin 1-Pin2 => TRIG2 input is T1 Pin 25 and T3 input not connected.



Note that these Trigger inputs are treated in exactly the same way by the TCU asthe SMB Trigger inputs on the front panel.

TCU control via explicit pulse programming.

This effectively means that bits can be set high or low for a minimum of 50 ns.

Timing Resolution: 12.5 ns.

This resolution is set by the 80 MHz clocking frequency. Bits can thus be set highor low for durations of 50, 62.5, 75 ,87.5 ns etc.

Pulse Rise Times: 5 ns

Pulse Fall times: 4 ns.

TCU control via explicit pulse programming. 4.7

The TCU outputs are normally set automatically from either the "edsp", "edasp" or"eda" tables or from the pulse program itself.

For test purposes however it is sometimes useful to explicitly program the variousoutputs using the following pulse program command:

d11 setnmr2^3 = set NMRWord 2 bit 3 high (inactive).

d11 setnmr2|3 = set NMRWord 2 bit 3 low (active).

d11 is the switching time and can be set as low as 50 ns ( the minimum duration.)

Once a bit is set high or low it will remain in this state until a further instruction toalter it's state is received. This syntax applies to all NMR words 0 - 8

A different syntax which is identical to that previously used in conventional RCPpulses can also be used, but only for NMR word 0 .

e.g. to activate (set low) BLKTR3 (see table 4.2.) for the duration p1 use:

p1:c2

e.g. to transmit a pulse p1 on channel 1 and simultaneously activate (set low)BLKTR4 for the duration p1 use:

p1:f1:c3

Note that unlike the "setnmr" command the bit will go inactive ( high ) as soon asp1 has elapsed.

Software Diagnostic Test 4.8

A useful test program is entitled "tcutest" which is normally in the directory:

/u/systest/tcu ( logged in on ’spect’)

Miscellaneous 4.9

The most important TCU outputs will be discussed in various Chapters throughoutthis manual ,but for completion several signals which will not be dealt with at laterstages are explained below



NMRWord8 bit4: SEL2H/DEC: This signal has been introduced to enable the 2H signal to the sample to beswitched. Normally the HPPR module transmits/receives the 2H lock signal. Incertain samples certain molecules may be labeled with 2H. At some stage in thepulse sequence we may want to switch off the lock and do normal 2H decoupling.Lockhold is activated and a switching box inserted after the HPPR 2H moduleswitches the signal transmitted to the probe from the Lock signal to the decouplingsignal.

NMRWord8 bit5,6:EXT DW: EXT RGP: These two outputs have been made available for solid applications.

NMRWord3 CAL, REGUL DROOP: These are signals which could be used to switch the amplifiers into a calibrationmode. As of yet the required hardware has not been implemented. In the future itis more likely that these modes will be switched using the RS485 link from theACB board.

FCU: Frequency Control Unit 5

Principal Functions 5.1

1. To generate the DDS input for the PTS. (Frequency and phase).

2. To control the frequency setting of the PTS output.

3. To generate MOD, MULT, AT20 and AT40 signals used for power regulation inthe ASU Boards.

4. To control the phase of the 4 Phase Modulator using ph1 and ph2 signals (Sol-ids measurements)

In many respects the FCU takes the place of the MCI board (see table 5.4.)

Front panel SMB. Connectors 5.2

Two signals, 40 MHz and AQS are daisy chained between successive FCUboards.

40 MHz. In/Out: This clocking signal originates from the 80 MHz of the TCU. It is TTL (2.5 - 3Vppat 50 Ω) and operates on a 50% duty cycle.

AQS In / Out: This is a TTL strobe pulse which is used to validate data transfer over the real-time Acquisition Bus. The strobe pulses go low for a minimum of 25 ns. The Datatransfer itself is triggered by the rising edge.

DDS out: 3 - 4 MHz. 0.8 - 1Vpp at 50 Ω.This signal goes directly to the PTS. Note that theDDS unit has a range of 0 - 10 MHz but only 3 - 4 MHz is used.

MOD MULT (Non Differential): These two outputs have been made available for transmitters with internal ampli-tude setting (i.e without external ASU). This would enable the FCU to drive trans-mitters such as the Ecoupler, BSV-10, BLT-4 etc..

The voltages delivered at the MOD and MULT outputs will depend on the load andhow the spectrometer is configured.


FCU: Frequency Control Unit

The non differential outputs will always be present, even when the differential out-puts are used (as is normally the case). As such they are a useful test point forchecking whether the MOD and MULT voltages are responding to the software.The values of MOD and MULT delivered at the non differential outputs for a spec-trometer configured as a AVANCE will be different from those above in table 5.1.

Note: The non-differential OP AMPs have a settling time of 180 ns. These outputshave a longer settling time than the differential outputs, which is 90 ns.

PH1, PH2:These two bits can be used to control the 0×, 90×,180× and 270× fast phaseswitching in a 4 Channel Modulator.

RUN LED:This LED will light whenever the FCU loops through a list

FCU Adapter 5.3

Each frequency generating channel of the spectrometer requires its own separateFCU board, with a maximum of 8 channels possible.

A single FCU Adapter is mounted on the front of each pair of boards. This Adaptercollects the blanking signals received from the TCU, as well as the MOD, MULTand AT signals generated within the FCU itself, and transmits them to the ASU viathe Connector F1 (see figure 5.1.). The Adapter, which effectively brings togetherthe outputs of two FCU Boards, is required because two FCU Boards are used todrive a single 2 Channel ASU Board.

FCU Adapter

Two signals TO/F and OBSF1, generated by the TCU and wired to the FCU areused only in DPX spectrometers.

A three channel spectrometer would contain three FCU boards. A special FCUMontage Kit (P/N H2569) is needed to enable the second FCU Adapter to bemounted. When ordering an upgrade kit to fit a spectrometer with extra FCUBoards it is important to specify which channel is to be added (i.e. channel 3 or 4etc.) so that the correct cables and ASU etc. is delivered.

Connector F1: 5.3.1

All TTL signals active low. After reset signals go high by default.

Jumper Positions. 5.5

An FCU is designated as FCU 1, FCU 2 etc. depending on the setting of jumpersW5 and not on the position in the AQX32 Rack. Figure 5.2 shows the correct set-ting of jumper W5 for various FCU Boards.

If a spectrometer is being upgraded with additional FCU Boards, or if aboard is being exchanged then jumper W5 must be set correctly.

Figure 5.2. Setting of Jumper FCU Jumper W5

To ensure 50 Ohm termination of the 40 MAI/40MAO and AQSI/AQSO signals,jumpers W2 and W3 of the last FCU in the chain should be left in. For all otherFCU's jumpers W2 and W3 should be out.

SRAM Memory 5.7

This memory is used to store instructions and data. The information is stored inlists consisting of 32 bit words -14 bit instruction and 18 bit data.

The 14 bit instruction consists of 9 bits instruction itself. Typical instructions mightbe load MOD, load phase, jump to address xxxx etc. The remaining 5 bits areused to specify the correct destination e.g. MULT DAC or PTS register etc.

The 18 data bits contain the specific values such as frequency values, phaseshifts, MOD, MULT and ATT values, etc.

A typical list to produce a shaped pulse might consist of a set of MOD values withor without delays in between. A start signal from the TCU enables the FCU to loopautonomously through the list to produce a digital output corresponding to the re-quired shape. The digital outputs are then loaded in the DAC to produce the ana-logue MOD output (see figure 5.5.).

Every list stored in the Static RAM must contain a start address which is stored inthe pointer register.

Number of pointer registers: Max. of 256

This effectively means that up to 256 lists can be accessed.

Each list requires a pointer.

Number of pointers. Max. of 256

As the FCU loops through a list the current position in the list is incremented. Theaddress of the current position is stored in the pointer.

Two sizes of on board RAM are available:

Standard: 64K x 32 bit words

Optional: 256K x 32 bit words.

The FCU Board Part Number depends on the size of the RAM: Standard: 64K (P/N H2556) Optional: 256K (P/N H2564)

NOTE: It is not possible to upgrade from 64K to 256K in the field.

The minimum duration possible is 50 ns resulting in a minimum time of 50 ns be-tween any two instructions. The FCU has a timing resolution of 25 ns so that dura-tions can have lengths of 50,75,100,125 ns etc.

Table 5.6 contains a list of processes which are carried out by the FCU and the re-quired time to carry out these processes.

Note that a PTS propagation delay of 2 us is not included.

MOD and MULT DACS 5.9

These DACS are 12 bit with a theoretical dynamic range of 72dB (1:4096) thoughin practice the full range is not used. For the implementation of the MOD andMULT signals see the Chapter on ASU's.

At the standard differential outputs the generated values of MOD and MULT willalways lie in the range of + 1V at 50 Ω. A comprehensive list of MULT values forvarious attenuation levels is listed in Table 6.7

Note: The MULT software control, with the exception of DAC voltage, can be eas-ily checked with the 'cf debug' command.

Amplitude settling time: 90 ns (incl. OP AMP)

The use of differential voltages for the MOD and MULT control have the followingadvantages:

a) Less susceptible to interference from clock frequencies such as the 40 MHzused on the FCU.

b) Less susceptible to offsets arising from power supply drifts.

c) Cancelling of induced voltages from 50/60 Hz pick up.

DDS Specifications

DMX: Three channels of the first PTS620 are used. FCU1 is connected to F1in, FCU2 toF2in, and FCU3 to F3in of the PTS.

The F2in channel of the PTS contains a triple mixer to generate magnet specific1H frequencies suitable for further mixing in the SE451. The only input require-ment for this channel is the 3-4 MHz DDS signal. This enables a third channel tobe used within the PTS620. The first 1H frequency is by default generated byFCU2 regardless of whether it is F1 or F2. By default FCU1 is used for F1, onlywhen it is an X frequency

DDS Specifications 5.11

The DDS units used by the FCU are identical to those used in the MCI.

Frequency Range: 0 - 10 MHz.

Used Range: 3 - 4 MHz

Frequency Stability: This is set by the stability of the PTS 10 MHz crystal oscilla-tor which is specified to 3 x10-9/day.

Frequency Resolution: The DDS unit is clocked by 20 MHz and the frequencysetting is stored in a 36 bit register

20 MHz/236 = 0.0003 Hz.

Phase Resolution: A 14 bit register is used to store phase values.

360°/214 = 0.022°

Phase Settling Time: 50 ns.

Connector F2 5.12

All signals active low except PTS doubling command.

After reset all signals go high by default.The pin assignments of connector F2 is detailed in the table below.

These signals are used to set the final output of the PTS 620. Unlike the MCIthese signals can be measured at the FCU output without the requirement that thePTS620 is connected. A simple way to check if the PTS control is operating inDRX/DPX instruments is to run a series of short acquisitions. The F1 of the PTSwill then switch rapidly from the SFO1 to SFO1 +22 MHz. This will cause some ofbits transmitted through connector F2 to switch rapidly. The switching should besynchronized with the acquisition so that the EP_HPPR is a handy triggering sig-nal. To observe the PTS control in DMX instruments a frequency list can belooped through or alternatively the bit settings can be viewed during the wobbleroutine



Figure 5.6. Cabling of PTS

Note that the signal FDBL is the doubling signal which is active whenever the PTS620 output is above 287 MHz. Thus for DRX/DPX spectrometers, the doublingsignal is required for 1H frequencies at and above 300 MHz and not required for Xfrequencies. For DMX spectrometers the mixing of frequencies with 440 MHz inthe SE451 means that the PTS doubler is not used for proton frequencies up toand including 600 MHz.For very low frequencies e.g. sfo1 = 50 MHz i.e PTS out-put = 390 MHz the doubler will be used.

For the DMX 750 a PTS 1000 is used with the frequency doubler switched in at500 MHz.

PTS Bit settings

The signal REN is the „Remote Enable“ signal which is normally tied to ground.

For the Pin Numbering (see figure 5.1.)

PTS Bit settings 5.13

The software setting of the PTS output frequency can be easily checked. Aftersetting the frequency in UXNMR the command „gotst“ will generate the file„shm.output“ in the user's home directory. This file contains the entry CONTFREQLD which is the PTS bit settings in hex. code. Alternatively the hex. codemay be checked with the „cf debug“ routine where it is stored as the parameterPTS Control Word.

In figure 5.7. are listed three examples of the hex. code for PTS output frequen-cies of 60, 75 and 300 MHz respectively. Remember that the PTS output is equalto the set frequency only for DRX/DPX spectrometers. For DMX spectrometersthe PTS output is given by SF + 440 MHz.

Overview 6.5

The PTS620 produces the required RF frequency on two identical broadbandchannels F1 and F3. Each channel produces frequencies in the range of 1 MHz -310 MHz, but with the aid of a frequency doubler at the final output, this range isextended to 1 MHz - 620 MHz.

In the DRX or DPX there is no subsequent mixing of frequencies in a SE451 typeTFX or TFH unit. The PTS620 generates the final RF frequencies SFO1 andSFO2

In the DMX there is subsequent mixing of frequencies in the SE451. For the OBSand DECNUC frequencies the PTS output is given by SF + 440MHz. The third rffrequency DECNUCB is generated directly.

Units

The fine resolution of the RF output is achieved by mixing frequencies generatedinternally in the PTS with signals (DDSCH1, DDSCH2) generated by Direct DigitalSynthesis in the FCU. In this way a frequency resolution of 0.0003 Hz and phaseresolution of 0.022° is achieved. The switching time between frequencies howeveris limited to that of the PTS.

Abbreviations:SGA, SGB: Standard Generators A and B

DMA: Digit Module A

IA: Input amplifier.

OA: Output amplifier

IM: Intermediate Mixer

SO: Switched Oscillator

Units 6.6

For the following section please refer to figure 6.2..

Crystal Oscillator: Produces a 10 MHz signal to a very high degree of accuracy (stability 3 x 10-9/day). This signal acts as a reference standard for all frequencies generated withinthe PTS.

SGA, SGB: uses the 10 MHz reference to generate the following frequencies 112, 113, 14, 16,18, 20 and 22 MHz. Of particular importance is the 18 MHz signal. The SGA mod-ule also produces signals of frequency (nx10) MHz where n is any integer from 1to 16.

Mixer: In this module the 3-4 MHz is mixed with 18 MHz to give frequencies in the 14-15MHz range. The DMA unit requires inputs of 14-15 MHz. It is in the mixer that thefine resolution of the RF output is entered.

DMA: This unit adds the required number of 1 MHz steps to the frequency. It also adds acarrier frequency so that the DMA output frequency always lies in the 140-150MHz range.

IM, SO, IA, OA: These modules combine to perform the following functions.

1. Addition of the selected 10 MHz steps

2. Output amplification and level control

3. Doubling of frequencies above 310 MHz and filtering of harmonics.


PTS 620

1. The final RF output frequency is given by the formula:

RF freq = output DMA freq + (n x 10 MHz)

where n may have integer values -14 to +16.

MINIMUM frequency = 140 - 140 = 0 MHz (output amplifier limits this to 1 MHz)

MAXIMUM frequency = 150 + 160 = 310 MHz

2. Level control is achieved through a feedback loop in the IM module.

3. In the OA module two possible routes may be taken depending on whether theselected frequency is above or below 310 MHz. The routing is controlled bythe doubling commands dblF1 and dblF3.

Note: In DRX and DPX spectrometers a 22 MHz IF is used. It is better when theSFO1 and the LO always use the same path i.e. they are both doubled or neitheris doubled. To ensure this, the software is programmed to switch in the doubler atSFO1 = 287 MHz. All frequencies below 287 MHz have a corresponding LO be-low 309 MHz which means that the doubler need not be used. Frequencies above287 MHz have an LO above 309 MHz and so both the SFO1 and the LO areswitched through the doubler.

Interface, AP: The information containing the frequency settings is ported via the interface to theAP. This module sends appropriate frequency settings to various modules. The 1MHz step information is sent to the DMA module. The 10 MHz information is sentto the SO module.

Trouble shooting

Figure 6.2. PTS 620 Block Diagram

Trouble shooting 6.7

1. As the two channels F1 and F3 in the PTS620 are identical, you can swap in-put offset signals i.e. replace "F3 in" with "F1 in" (Set SF01 = SF02). This isuseful when trying to establish if a problem is internal or due to incorrect FCUoffsets. Furthermore you can interchange modules between the two channelsto locate the source of a problem.

SF01 = 300.0000000 MHz => DDSCH2 = 4.0000000 MHz

SF01 = 500.1300000 MHz => DDSCH2 = 3.8700000 MHz

3. Two potentiometers are available with which the output voltages may be ad-justed.

"F3 out" may be adjusted by means of the potentiometer located immedi-ately to the right of the synth1 socket. To adjust the amplitude of "F1 out" itis necessary to open the PTS and adjust the potentiometer located underthe OA1 module.

4. Checking the frequency setting:

As mentioned in the Chapter on FCU's it is much simpler to measure the bit set-tings at the FCU output connector F2 rather than at the Synth1 input.

Adding extra channels 6.8

DMX: The first PTS620 will provide three frequencies as long as at least one frequencyis proton. The addition of a fourth channel will require a second PTS.

DRX: The first PTS 620 will provide a max. of two channels. The addition of a thirdchannel will require a second PTS 620.

DPX: The DPX may be configured with a max of two channels.

When a single extra channel is to be added then a single channel PTS is avail-able. This PTS is fitted

a) without the internal time base (10 MHz)

b) without 22 MHz and 80 MHz outputs.

c) with 5 x 10 MHz outputs.

When two additional channels are to be added then a standard dual channel PTS620 will be supplied.

The additional PTS units are referenced to an external 10 MHz source takenfrom the first PTS 620 and in this way the two synthesisers are synchronised.


Adding extra channels

Note: Always choose 10/5 for the 10MHz input to the LO Board of the SE451 asthis PTS output is particularly spurious free.

LOT Board 7

The LOT Board (Local Oscillator and Tune Board P/N W1301855 ) is system fre-quency independent and used exclusively in DRX spectrometers. The LOT Boardis a switching device using FET (GaAs) NE630D components with a switchingspeed of 20 ns.

A variation of this board, the LOT/ASU ( W1301854 ) is used in DPX spectrome-ters. The DPX Board combines the T/R switching, the wobble routine and theMULT, ATT functions in one board ( The MOD function however is not provideddue to space limitations). For the purposes of this manual the LOT Board and theASU Boards will be described separately.

Functions 7.1

1. To implement the T/R switching on the observe channel.

2. To provide a "tune out" and "LO" signal for the wobble routine.

1. T/R switching:

During the transmit mode (see figure 7.2.) up to two rf inputs (LTI1, LTI2), areconnected directly to two corresponding outputs (LTO1, LTO2). In this mode theLOT Board simply lets the rf signals through.

In the receive mode the frequency of the rf signal of the observe channel isswitched to the LO frequency and redirected to the receiver via the output LO12.The timing of the T/R switching is controlled by means of the RGP (EP) pulse. TheLO frequency always has the value SFO1 + 22 MHz. The 22 MHz is added to theSFO1 frequency within the PTS 620. This effectively introduces a switching de-lay(<5ms). Since DE = 4.5ms by default, the T/R switching has an effect (if any)on the first digitised point only. Note that should the first point be critical then thedefault DE can be extended.

2. Wobble Routine:

The RF path used by the wobble routine is illustrated in figure 7.4.. Note that theLOT hardware is such that Channel 2 is always used to provide the "FTUNE" out-put.

Signals

the signal that needs to be correctly set. This signal will automatically be set lowonce an observe nucleus has been selected in the "edasp" or "edsp" menus andthe corresponding interface initialised. The signal will reset high after the "stop"command has been entered or when a hardware reset of the CCU is carried out.(For TCU Boards up to and including Layout C, the pull-up resistors are notmounted on the TCU T4 outputs and so the signal should be checked on the LOTBoard itself and not at the TCU output.)

The signal OBSCH2 (OBSF2) allows for the possibility of using the second rf input(LT I2) as the source of the LO signal .This option is normally not used .

The signals OBSCH3 (OBSF3) and OBSCH4 (OBSF4) are not used at present .They allow for the possibility of using the LOT Board to carry up to 4 rf frequen-cies. This option may be implemented in the future for example to switch the ob-serve nucleus during an experiment.

NOTE1: For the standard LOT Board only signals OBSCH1 and TUNE ON are actuallyconnected in the console wiring.

NOTE2: In DMX spectrometers the signal OBSCH1 is used to select either the H or Xchannel as the observe channel in the SE451. In the new 19 inch SE451 ( 3 chan-nel capability) signals OBSCH1, OBSCH2 and OBSCH3 will be used to select theobserve channel.

RGP (EP):This signal, as measured on the board itself, is low for the duration of the acquisi-tion ( receiver open ) and high at all other times. The RGP (EP) signal, originatesin the RCU and is transmitted to the SADC via the 50 pin cable. From here it isconnected to the LOT Board via the back panel.

PAL LOT 1 ( EP610 ):In DRX spectrometers the chief functions of this Pal are to produce the F1>LOand BLKLO signals.

F1>LO :This signal is used to implement the T/R switching on the F1 channel . It is pro-duced by combining the RGP (EP) and OBSCH1 signals. The signal is high dur-ing transmission but goes low for the duration of the acquisition.

TGPENAB (SPENAB):This signal is not actually used on the LOT Board but can be measured on theboard at the backpanel connection. The signal is low during rf transmission. Aftera power down from the BSMS keyboard the signal goes high.

Power Supply:The LOT Board is powered from the back panel via connector J1. The same pow-er supply board (W4P31377) is used for both the LOT and the ASU Boards.

ASU: Amplitude Setting Unit 8

Functions 8.1

1. To set the amplitude of up to two rf signals using the MOD, MULT, AT20 andAT40 signals.

2. To blank the rf signal using the TGPCH and BPCH signals

The ASU performs functions which in AMX and ARX spectrometers were carriedout internally within the transmitters themselves. The AVANCE amplifiers nowserve as pure amplifiers, they carry out no power regulation or setting. The finaloutput of the BLAX300, BLAXH40 etc. will be a linear function of the rf input inten-sity.

The ASU board is system frequency independent up to 600 MHz and compatiblewith all of the new range of linear amplifiers BLARH100, BLAX300, BLAXH50 etc.(The 750 MHz DMX uses the same ASU board with selected components to ex-tend the bandwidth to 750 MHz.). There is no distinction between ASU boards forDRX and DMX spectrometers. The DPX spectrometer however uses a dual pur-pose ASU/LOT board without the MOD section. For this reason shaped pulsesare not possible with DPX spectrometers.

Standard ASU boards are capable of independently setting the amplitude of two rfchannels. The input rf signals (AI1, AI2) have a maximum intensity of 1VPP (4dBmat 50W). These inputs come from either the SE451 (DMX) or LOT board (DRX).

Where more than 2 rf channels are used*, then a second ASU board must be fit-ted.Three channel spectrometers are fitted with a single channel ASU (P/NW1301853). Four channel spectrometers simply use a second standard 2 chan-nel ASU (P/N W1301852) The third and fourth rf input signals are taken directlyfrom the respective PTS outputs.

*Note that the DPX spectrometer has a maximum of 2 channels.

The ASU receives the MOD, MULT, AT20, AT40 and various blanking signals fromthe FCU via the 50 pin SCSCI Type front panel connector (table 8.1.).Note thatthe connection to the FCU is one to one.

In ARX and AMX transmitters a PAS-2 switch was used to implement the MULTcontrol. To correct for non-linearity, a correction factor had to be applied. In theASU the PAS-2 switch has been replaced by an analogue multiplier, with a farhigher degree of linearity. Other improvements are the switching speed as well asthe phase linearity and blanking control. The table 8.3. summarizes the differencebetween the previously used PAS-2 and the analogue multipliers which are nowused

The minimum MULT attenuation corresponds to a software Power Level setting of-6dB. For a pl value of -6dB the MULT hardware actually attenuates by 0dB. Thecorresponding output of the ASU is 1Vpp (4 dBm.). For the commonly used rangeof 0 to 20dB the corresponding hardware MULT attenuation is 6 to 26 dB (see fig-ure 8.2.). This has been so programmed because within the hardware attenuationrange of 6 to 26dB the phase shifts are minimum.

MOD:Shaped pulses are produced by applying a combination of the MOD and MULTvoltages. The MOD signal is used to control the shape, the MULT to vary the over-all amplitude of the shape envelope. The ASU units use Analogue Multipliers forthe MOD control instead of the Ring Mixers used in previous transmitters. Thenew Multipliers result in smaller phase shifts, have a slightly larger range and bet-ter linearity.

Two analogue multipliers set in series allow a modulation of up to 60 dB within asingle shape. The MULT signal is used to vary the overall amplitude of the shapedpulse and is normally maintained within the range of 0 to 30 dB. In conjunctionwith the 20 and 40 dB fixed attenuators, this gives a range in attenuation of over90 dB.

Larger MULT attenuation (between 30 and 50 dB) is possible but slightly largerphase shifts may arise at frequencies beyond 500 MHz.

MOD and MULT gating 8.3

Nomenclature: SPF1 = TGPCH1 SPF2 = TGPCH2 (Transmitting Gating Pulses)

TGPENAB(SPENAB) is normally permanently low, unless a power down reset isactivated from the BSMS keyboard. The TGPCH signals from the TCU are simplycombined with the TGPENAB through an „or“ gate to produce the SPFMULT andSPFMOD signals. The SPFMULT and SPFMOD signals (active low) are thenused to gate the MOD and MULT sections. Thus the gating signals will go low (ac-tive) only when either TGPCH1 or TGPCH2 is low. This allows precise gating con-trol of the MOD and MULT units which improves the on/off ratio. This gating wasnot implemented with the internal MOD and MULT units of previous transmitters.Note that the timing of TGPCH signals may not be altered using the „edscon „ta-ble.

Nomenclature: BLKF1 = BPCH1 BLKF2 = BPCH2

The signals AT20FM1, AT40FM1, AT20FM2 and AT40FM2 are used to blank theattenuators and are active high (attenuator switched on).

The logic of the PAL ASU02 is such that the 20 and 40 dB attenuators are auto-matically active whenever rf signals are not being transmitted. Outside of pulsetransmission BPCH is high and therefore the 20 and 40 dB attenuators are by de-fault active. This new feature ensures minimum noise outside of the transmittedpulses. Whether the 20 or 40 dB attenuation is applied during the pulse transmis-sion itself depends on the signals AT20 and AT40. If these signals are low thenthe attenuators will be switched off.

The timing of BPCH signals may be altered using the „edscon „table. The corre-sponding edscon parameters are BLKTR[1-8].

Router/Combiner 9

Introduction 9.1

The standard router has 3 inputs and 5 outputs. Not every routing option is al-lowed as detailed below.

Input 1 may be routed to Outputs 1, 2 or 3.

Input 2 may be routed to Outputs 1, 2, 3 or 4.

Input 3 may be routed to Outputs 1, 2, 3, 4 or 5.

The implementation of all possible routing would

a) make the physical size of the router too large

b) increase crosstalk

c) increase cost.

RSEL Parameters 9.2

How a particular signal is routed is determined by the setting of the RSEL controlwords. These are software parameters which are set from the „edsp“ menu. Thevalues are normally hidden from the user but can be simply checked by enteringthe parameter at the keyboard*.

The routing of INPUT1 is determined by the value of RSEL1, the routing ofINPUT2 is determined by RSEL2 etc.

* Note that the syntax is „0 space RSELspace 1 enter “ etc.

Where a router input is not used then the corresponding RSEL word is assigned avalue of 0.

The actual hardware switching of the router is realized by means of the RSEL bitswhich are detailed in figure 9.1.. These bits are active low, generated by the TCUand transmitted to the Router via the 50 pin SCSI cable from TCU connector T2.

The software parameter RSEL1 is implemented using hardware bits RSEL_10,RSEL_11, RSEL_12 and RSEL_13. Similarly the software parameter RSEL2 isrealized by hardware bits RSEL_20, RSEL_21, RSEL_22 and RSEL_23 etc. Thebit settings can be checked at the J3 28 Pin SCSI connector at the router frontpanel.


Router/Combiner

Figure 9.1. Explanation of RSEL Parameters

The fact that all possible routing is not allowed naturally imposes restrictions onthe possible combining.

Combining:Output 1 can be any combination of Inputs 1, 2 and 3.

Output 2 can be any combination of Inputs 1, 2 and 3.

Output 3 can be any combination of Inputs 1, 2 and 3.

Output 4 can be a combination of Inputs 2 and 3.

Output 5 is taken directly from Input 3.

Output Blanking 9.3

Each router output must be blanked by the corresponding pulse i.e. Output 1 byBLKTR1, Output 2 by BLKTR2 etc.

All the output blanking pulses are active low, generated by the TCU and transmit-ted to the Router via the 50 pin SCSI cable from TCU connector T2.

Router/Combiner

The banking pulses can be checked at the J3 28 Pin SCSI connector at the routerfront panel.

The precise timing of the output blanking pulses can be altered with the „edscon“parameters BLKTR[1 - 15].

TGPENAB 9.4

The router is designed to be completely disabled if the TGPENAB signal shouldgo high. This will happen if the TRANS P-DOWN key of the BSMS keyboard ispressed. The signal is transmitted via the ACB to the ASU's, the LOT and routeralong the AQR backplane. To check this signal you will need the AQR EXT. Board(P/N Z012746). The signal can be measured between Pins 9a and 9b and forpower transmission must be low.

Cascading routers 9.5

For the present a standard cascade arrangement for two routers has been decid-ed upon. This standard arrangement is necessary if the „edsp“ display is to cor-rectly control the hardware. Note that if the software detects more than 3 FCU’sthen it will assume that a second router is fitted. (The AQR can accommodate upto 3 routers which can, from the hardware viewpoint, be cascaded in differentways but this will not be automatically supported by the software.)

The figure 9.3. shows an example where two routers are cascaded. The soft-ware treats the two routers effectively as a single router. Input 3 of Router 1can not be controlled directly by a separate RSEL software word. Insteadthe software automatically routes Input 3 of Router1 correctly, depending onthe requirements for Output 1 of Router2.

Cascading routers

For router2 the three inputs are controlled by software words RSEL 3,4 and 5.The corresponding hardware bits are:

RSEL_ 40, RSEL_41, RSEL_42, RSEL_43


RSEL_60, RSEL_61, RSEL_62, RSEL_63

This inconsistency in the numbering is unavoidable since all routers are identicalin terms of hardware.

For router3 the corresponding software words would be RSEL 6,7 and 8 with cor-responding hardware words are:



RSEL_90, RSEL_91, RSEL_92, RSEL_93

The software is programmed to automatically take account of the cascade ar-rangement. For example if as in figure 10.3 the third rf channel is linked to the am-plifier connected to RO5 then the software will set RSEL3=5 and automatically setHardware bits RSEL_ 30, RSEL_31, RSEL_32, RSEL_33 and RSEL_40,RSEL_41, RSEL_42, RSEL_43 correctly. Furthermore the BLKTR5 and BLKTR6pulses will automatically be generated.

Similarly referring once again to figure 9.3., if software route RSEL4=6 is chosenthen RSEL_ 50, RSEL_51, RSEL_52, RSEL_53 are set correctly and BLKTR7 isgenerated.

The input connector to each Router is a 28 pin SCSCI type J3. Output T2 of theTCU is capable of controlling one or two Routers.

For one Router Cable (P/N H5570) is used, for two Routers the cable (P/NZ002814) is used.

BRUKER Linear Amplifiers 10

New features 10.1

Among the new features of the latest range of power amplifiers are:

1. The output amplitude is a linear function of the amplitude of the rf input. Unlikeprevious transmitters no power setting takes place within the amplifier itself. Assuch they are referred to as amplifiers and not transmitters.

2. New safety features (OVERDRIVE, PULSE WIDTH, DUTY CYCLE) which willtemporarily disable the amplifier whenever output power is above a specifiedlimit. Each amplifier has on board information stored in the RS485 InterfaceBoard regarding amplifier type, max. Duty Cycle, max. Pulse Width etc. Theseparameters can be changed by software if necessary.

3. The amplifiers are controlled by the ACB (Amplifier Control Board) via anRS485 type link (SBS Bus). Individual Amplifiers can be addressed. Hardware address codes are set via a HEX. switch located on the amplifier front panel.Read and write access to the BLA Control board II is possible via the ACBBoard.

4. Improved LED front panel display with diagnostic information regarding PulseWidth, Duty Cycle, Temperature etc.

5. Precise software timing control of the amplifier blanking pulses (BLKTR1..15)via the „edscon“ table.

Terminology 10.2

BLARH 100 = BRUKER Linear Array Amplifier for 1H with 100W High Powerchannel.

The „array“ refers to the fact that the unit contains more than 1 amplifier connect-ed to the same output channel.

BLAX 300: BRUKER Linear Amplifier for X frequencies with single channel 300Wamplifier.

Brief Summary of standard Amplifier Types 10.3

1. BLARH 100:

This is a standard DMX amplifier with three 1H/19F rf channels.

Input HHigh - 100 W output for rf input of 4 dBm.


BRUKER Linear Amplifiers

Input HLow - Output power 50 dB lower than high power channel. Thiswould correspond to an output of 1mW for rf input of 4 dBm.

Input HMed - 10 W output for rf input of 4 dBm.

A variation of this transmitter is the BLARH50 with a HHigh channel max.output of 50W instead of 100W. At the moment this amplifier is fitted to 750MHz spectrometers, but a 100W version will be introduced if required.

2. BLAX 300:

This is the standard DMX X frequency amplifier with a single channel X fre-quency amplifier.

Input Xin - 300W output for rf input of 4 dBm.

3. BLAXH 50:

This is the standard DRX amplifier with three rf channels, two for 1H/19F,one for X frequencies.

Input HHigh: - 50W output power for rf input of 4 dBm.

Input HLow - Output power 50 dB lower than high power channel.

Input Xin - 100W output power for rf input of 4 dBm.

4. BLAXH 20:

This is the standard DPX amplifier with two rf channels, one for 1H/19F, onefor X frequencies.

Input H - 20W output power for rf input of 4 dBm.

Input X - 100W output power for rf input of 4 dBm.

A comprehensive list of available amplifiers with Part Numbers is given onthe next page. Data sheets in the Appendix give precise specifications ofthe above amplifiers.


RF Output Power: Comparison with previous transmitters

Figure 10.1. Overview of Standard Amplifiers

RF Output Power: Comparison with previous transmitters 10.4

The input and output impedance of all linear amplifiers is 50 Ω. In AVANCE instru-ments the rf input for each amplifier comes directly from the router. The max. rf in-put amplitude is 1Vpp (4 dBm at 50 Ω) corresponding to a software power levelsetting of pl = - 6dB.

Using the standard DMX BLARH 100 HHigh channel this input would produce aminimum output of 100W. The corresponding output for pl = 0 dB is 25W. Thus pl= 0 dB with the BLARH 100 corresponds roughly to HL = 3 dB using the standard50W Ecouplers as in AMX spectrometers.

The BLT 4 transmitter used in ARX transmitters had output powers of 40 W(1H)and 100 W (X) respectively for an input of 1Vpp (4 dBm at 50 Ω). The outputs ofthe BLAXH50 will be 50 W (1H) with a software setting of pl = - 6 dB. The corre-sponding X output is 100 W (200 - 400 MHz) and 300 W (500 - 600 MHz)

Amplifier Blanking 10.5

The blanking pulses (BLKTR 1... 15) are active low TTL level and produced by theTCU. They are easily measured at the BNC connections on the amplifier frontpanel. Which blanking pulse is required for which amplifier will depend solelyupon which router output provides the rf amplifier input. This is because the sameblanking pulses are used to blank the router output as the amplifier. Thus an am-plifier channel connected to router output RO1 will be blanked by BLKTR1. Anamplifier channel connected to router output RO3 will be blanked by BLKTR3 etc.The timing of the BLKTR[1... 15] pulses can be adjusted with the „edscon“ table.

Configuration for DMX spectrometers (1 Router) 10.6

Table 10.1 lists the connections between the router outputs and a possible ar-rangement of amplifiers in a DMX spectrometer. In order for the „edsp“ display tofunction properly certain requirements are necessary. Firstly that the Hex Addresswhich is set on the front panel of each amplifier must correspond to the router out-put to which the first amplifier input is connected. (For the BLAXH50 this is Xin, forthe BLARH100 this is HHigh)

Secondly auxiliary amplifier inputs must be connected in the correct order.

For example when the software detects that a BLARH100 has Hex. address of 2then it will assume:

a) that output 2 of the router is connected to HHigh.

b) that outputs 3 and 4 of the router are connected to HLow and HMed re-spectively.

Figure 10.2. Standard DMX with one Router

Configuration for DMX spectrometers (2 Routers) 10.7

When 2 Routers are installed then a standard cascade arrangement is required inorder for the „edsp“ display to function properly. This involves connecting RO1 ofRouter 2 to RI3 of Router 1. The third rf channel is connected to RI1 of Router 2. Abrief glance at figure 10.3. will show that this arrangement allows any combina-tion of rf channels 3,4 and 5 to be routed to any output of Router1. The customeris then at liberty to connect any arrangement of amplifiers as long as the frontpanel Hex. addresses are numbered in sequence.

BLA Controller board II

Figure 10.6. Standard DPX Configuration

BLA Controller board II 10.11

Among the functions performed by the BLA II Controller board is the operation ofthe PULSE WIDTH and DUTY CYCLE functions.

A saw tooth signal is used to measure the pulse width. This is then combined withthe transmitted power as detected by the directional coupler. If the product of thepower and pulse width exceeds specified limits then the PULSE WIDTH functionwill be activated and the amplifier temporarily disabled. The maximum allowedpulse width is inversely proportional to the transmitted power.

e.g. the BLAX300 is specified as having a maximum pulse width of 20ms at300W. At 200W the max. allowed pulse width is 30ms, at 100W 60ms etc. until at30 W the power is deemed low enough to allow cw operation.

The DUTY CYCLE function operates as follows. The extent to which a capacitor ischarged can then be taken as a measure of the duty cycle. This is then combinedwith the transmitted power as detected by the directional coupler. If the product ofthe power and duty cycle exceeds specified limits then the DUTY CYCLE functionwill be activated and the amplifier temporarily disabled. The maximum allowedduty cycle is inversely proportional to the transmitted power.

e.g. the BLAX300 is specified as having a maximum duty cycle of 10% at 300W.At 200W the max. allowed duty cycle is 15%, at 100W 30% etc. until at 30 W thepower is deemed low enough to allow 100% duty cycle i.e. cw.

Note: There is no corresponding LOW CHANNEL ON simply because the powerlevels are too low.

Figure 10.7. Amplifier Front Panel

OVERDRIVE:

This LED will light whenever the output power of the high power channel exceedsthe specified cut out level. The default cut out level is twice the nominal outputpower. A cut out might be caused when the input rf was somehow greater than1Vpp. The amplifier would then be temporarily disabled for 1 - 4 s. After this peri-od has elapsed the amplifier will be automatically re-enabled. Further detection ofexcessive output power will disable the amplifier for a further 1 - 4 s. This processwill continue until the cause of the overdrive is removed.

The specified cut out level may be adjusted within the range of [0.5 - 2] x [NominalOutput Power]. e.g the specified cut out level for a BLAX300 can be varied be-tween 150W and the default value of 600W.

DUTY CYCLE:This LED will light if the specified max. Duty Cycle of the amplifier is exceeded.The amplifier itself will be temporarily disabled as described in the section OVER-DRIVE above.

Note that 10W and 1W 1H/19F amplifiers have no DUTY CYCLE limitations.

Note that the 10W and 1W 1H/19F amplifiers have no PULSE WIDTH limitation.

MISMATCH:This LED will light whenever the reflected power is above a specified level. Thislevel corresponds at maximum power to a VSWR of 6 which corresponds to 50%reflection of forward power. The MISMATCH function is active for the high poweroutput only.

CW LIMITATION ON:In normal operation the CW LIMITATION ON LED is not lit.

With an RS485 command the normal operating status can be altered to switch offthe internal DUTY CYCLE and PULSE WIDTH limitations. In this mode the CWLIMITATION ON LED will light. The OVERDRIVE function will still however be ac-tive. If the average output power is above the specified limits then the amplifier willautomatically switch off for 1 - 4 s.

This CW LIMITATION feature is due to be replaced by the MULTIPULSE ON fea-ture (see below)

MULTIPULSE ON:This function is not implemented in the earliest amplifiers and is intended to re-place the CW LIMITATION ON function. In normal operation the MULTIPULSEON led is not lit.

With an RS485 command the normal operating status can be altered to switch offthe DUTY CYCLE limitation (the PULSE WIDTH function is still active!). In thismode the MULTIPULSE ON LED will light.

This was designed for experiments such as CRAMPS where the Duty Cycle maytypically be 50% even though this represents no risk to the probe. The OVER-DRIVE function will still however be active. If the average output power is abovethe specified limits then the amplifier will automatically be disabled for 1 - 4s.

Note that the software setting of the MULTIPULSE ON function is not yet imple-mented.

OVERHEAT:A temperature sensor located within the amplifier monitors the temperature.Should the temperature rise above specified limits (non-adjustable) then the am-plifier will automatically be disabled. The amplifier will remain disabled until thetemperature has dropped sufficiently whereupon it will be automatically re-en-abled.

RF POWER FAULT:This is a general diagnostic LED which lights whenever any other LEDs in thesame display column light.



Front Panel Display for DPX amplifier 10.13

In order to reduce costs and due to it’s reduced power capabilities this amplifierhas not the same protection features or front panel display as with other amplifi-ers. The LED on the front panel will light to signify power transmission (up to 25dBof max. output).

Note that the only protection feature is an OVERHEAT function which effectivelyswitches the amplifier off should the output power cause the amplifier to warm suf-ficiently. The amplifier will remain disabled until the temperature has dropped. Thecorresponding power at which the temperature cut out is activated will depend onfactors such as room temperature and console ventilation. However the customershould be advised not to operate at full power with a Duty Cycle above 10%. Fur-thermore the customer should ensure that cw operation at too high a power doesnot damage the probe. As a general rule cw operation should not exceed 2 - 3 W.This would correspond to a power level setting of pl = 10 dB (X channel) and pl =3dB(1H channel)

The unit has 3 separate rf inputs see figure 10.9.. For inputs of equal amplitudethe HHigh channel will have an output 20 dB higher than the HLOW when mea-sured before the directional coupler. In the directional coupler the HLOW channelis further attenuated by 30 dB. Thus the HLOW channel final output power will be50 dB of the HHigh output for rf inputs of equal amplitude. The use of this amplifierarrangement has the advantage of expanding the overall dynamic range from amax. of 110 dB available from a single amplifier to 160 dB available from the com-bination (see figure 11.8). The HLOW channel is designed for applications that re-quire long pulses with corresponding very low power.

The HMED channel option should prove particularly useful for 1H/19F decouplingexperiments. The figure 10.10. and the figure 10.11. show the rf paths forOBS1H/Dec 19F and vice versa. Note that there is no need for switching withinthe BLARH 100 for this type of experiment as long as the decoupling power is lessthan 10W.

The XBLA input is designed to be taken from the BLAX 300 output. With the aid ofthe internal switching different rf inputs can be easily switched to the same output.This is particularly useful if a QNP HPPR module is connected to the QNP amplifi-er output because 19F or X frequencies can be transmitted without any need forrecabling.

The pin diode has a switching speed of less than 10us and is controlled by theTCU produced NMRWORD2 bit 2. The rapid switching speed is required only for19F or 1H decoupling experiments where the decoupling power is greater than10W.

The mechanical relay has a switching speed of less than 10ms and is controlledby the TCU produced NMRWORD2 bit 3.

The setting of the mechanical relay will decide whether:

a) a 19F signal is switched to the 19F/Xsel or XQNP output

b) the XBLA input is switched to 19F/Xsel or XQNP output

Since the switch will be set at the start of the experiment (depending on HPPRconfiguration) a switching speed of less than 10ms is more than adequate.

The use of the HHIGH and HLOW amplifiers to expand the overall dynamic rangeis identical to the BLARH 100 (see figure 10.13.). The only difference is that 50Wand 0.5W amplifiers are used instead of 100W and 1W. As with the BLARH100,

the output of the HLOW channel will always be 50dB of the HHIGH output for thesame rf input amplitude. The X in input of the BLAXH50 comes directly from therouter whereas in the BLARH100 it can be taken from the output of the BLAX300.

BLAXH 50 Output Switches 10.17

The two 1H/19F inputs (HHIGH and HLOW) and the X in input may be switchedbetween the outputs 1H, 19F/Xsel and XQNP using any combination of the pin di-ode and relay switches.

These switches are specified as having:

a) Typical Isolation of >50 dB at 600 MHz

b) Insertion Loss of < 2 dB at 600 MHz.(includes Directional Coupler)

The setting of these switches can be controlled within the „edsp“ display. The rel-evant software parameters are SWIBOX [1 - 8] (see chapter 18).

The pin diode has a switching speed of less than 10us and is controlled by theTCU produced NMRWord2 bit 2. The rapid switching speed will be required for19F/1H decoupling experiments where the rf signal is switched between the 1Hand either of the other two outputs. The corresponding software commands are„foh“ (switch to 1H) and „fox“ (switch to either 19F/Xsel or XQNP). Note that withthe BLAXH 50 it is not possible to transmit 19F and 1H simultaneously.

The mechanical relay has a switching speed of less than 10 ms and is controlledby the TCU produced NMRWord 2 bit 3.

The setting of this mechanical relay will decide whether:

a) a 19F signal is switched to 19F/Xsel or XQNP output

b) the Xin input is switched to 19F/Xsel or XQNP output

Since the switch will be set at the start of the experiment (depending on HPPRconfiguration) a switching speed of 10 ms is more than adequate.

Note however that for BLAXH50 amplifiers the board is fitted with an additionalpiggyback board to cater for the second BLA Controller Board.

Functions:1. To digitize the Forward, Reflected and Blanking signals received from the BLA

Controller Board and transmit them to the ACB. From here they are either dis-played on the Boss Keyboard or the graphics monitor.

2. To provide read/write access to amplifier parameters such as Pulse Width Lim-itation, Max. Duty Cycle, FORW and REFL power.

3. To enable new application software to be downloaded.

4. Storage of data regarding number of amplifiers and amplifier type.

The RS485 link operates at a fixed baud rate of 62500. The RS485 data transmis-sion uses the SBS standard of 8 bits data with 1 start bit and 1 stop bit.

The principal elements of the RS485 board are:

U22:Among other subunits this microprocessor contains eight 8 bit sample and holdunits. Four are used to digitize the Forward and Reflected signals (2 channels),the other four are reserved for internal diagnostic tests.

U10:This EPROM contains the boot software. Note that new boot software cannot bedownloaded over the RS485 link. In the unlikely event of new boot software beingrequired then the EPROM itself must be exchanged.

U2:This FLASH EPROM contains the application software used by the board. Newapplication software can be downloaded over the RS485 link.

U9:This contains 32K of RAM.

U4:This chip has 4 x 8 bit DACs used to set the Duty Cycle, max. Pulse Width andOVERDRIVE cut out level.

U14, U15:These monoflops are used to extend the duration of the BLKTR pulses to a fixedduration 70 ms regardless of the pulse length. This is so that the power displaymay be more easily observed.

U27, U28:These monoflops perform the same function to the Forward and Reflected sig-nals.



U11:This EEPROM contains the BBIS information regarding the board itself as well asinformation regarding the number and type of amplifiers.This information, com-bined with the Hex. address is used to customize the „edsp“ display to the partic-ular spectrometer. The BBIS data may be read from or written to over the RS485link. The EEPROM stores up to 256 bytes of data.

U24: This PAL is used to decode the various select signals.

Jumper Settings 10.18.2

J1, J2To ensure galvanic isolation of the RS485 front panel connector from the InterfaceBoard jumpers J1 and J2 should be set as in the figure below.

Figure 10.14.Jumper Settings to ensure Galvanic Separation

J4, J6:These jumpers are populated only for transmitters with three amplifiers and nopiggyback board. At the moment this is either the BLARH100 or BLARH50. For allother transmitters these jumpers are not populated.

J7:Normally this jumper is not populated. However in certain circumstances it can beadvantageous if only the Boot software runs and the application software is notactivated. This can be helpful if a crash of the application software results in ablockage in the downloading of new application software. If this is the case jumperJ7 can be inserted and the Boot software will run without attempting to activatethe application software. The new application software can then be downloaded.

Reset button: This is located on the amplifier front panel to the left of the Hex. switch. With a re-set all parameters such as Duty Cycle, Max. Pulse Width etc. are reset to themaximum default value set in the factory.

Hex switch:This is used so that each RS485 board (and consequently each amplifier housing)has a unique SBS address.

NOTE: To avoid a blockage of the SBS Bus the RS485 cable should first be dis-connected before switching an amplifier off. Switch on the amplifier before recon-necting the RS485 cable.

RS485 signals 10.18.4

TXD+, TXD-:TXD+ and TXD- form a twisted pair. The RS485 link uses differential transmissionlines. These transmission lines can be driven only by the master (ACB). Becausethe slaves (amplifiers) cannot drive these lines (they can only receive) a bus con-flict is avoided

RXD+, RXD-:RXD+ and RXD- form a twisted pair. The receive lines are also differential. Theslaves use these lines to transmit data. The master cannot drive these lines, it canonly receive. A bus conflict caused by more than one slave attempting to transmitis prevented by software.

Note: Slave to slave data transmission is not allowed!

WUP:This is a Bruker specific RS485 compatible signal. To avoid interference the soft-ware can switch off some slaves during acquisition (sleep mode). To restart theslaves outside of acquisition the WUP signal is used to carry out a hardware reseton the slaves. The WUP is active low and driven by the master only.

VRS:Power supply of 12 V. This is provided by the ACB

Termination:The RS485 bus must be terminated correctly. A special connector is provided (P/N H5167)

Amplifier Specifications 10.19

A comprehensive list of specifications is now available for all Bruker linear amplifi-ers. This section describes how these specifications are defined. Example fig-ures quoted here refer to the specifications of the BLAX 300 RS which arecontained at the end of this chapter.

FREQUENCY RANGE:A measure of the frequency range over which the amplifier is designed to beused. RF signals at frequencies outside this range may have significantly reducedgain.

GAIN FLATNESSThe amplifier gain will be somewhat dependent on the absolute frequency. TheGAIN FLATNESS is quoted for the specified frequency range. e.g. for the BLAX300 RS the gain is specified not to vary by more than 1.5 dB for any frequencywithin the 6 - 241 MHz range.


Amplifier Specifications

LINEAR GAIN:This is measured well within the linear region of the amplifier, typically at 10 dBbelow max. output. The linear gain will differ from the gain at the specified max.output. For the BLAX 300 RS an input of 1Vpp (4 dBm) will produce an output of300 W(55 dBm) i.e gain = 51 dB.

A brief glance at figure 11.17 should show however that the gain within the linearregion will be greater (in the case of the BLAX300 54 dB).

Figure 10.16.Linear Gain for BLAX300 (not to scale)

CW OUTPUT POWER:The BLA Control Board II limits the maximum allowed output power in CW modeto the specified value.

LINEAR OUTPUT POWER:At high output powers the linearity of the amplifier will suffer. The amplifier is de-fined as linear up to the power level where the actual output deviates from the per-fectly linear output by 1 dB. This level is referred to as the 1 dB compression point(see figure 10.17.)

Input

OutputLINEAR GAIN = 54 dB

GAIN at max output = 51 dB

gain



Figure 10.17.Linear Output Power (not to scale)

AMPLIFIER BIASING:All Bruker linear amplifiers are class AB.

BLANKING DELAY:The blanking within the amplifier is implemented using MOSFET's. These transis-tors have a certain response time and should ideally be activated prior to the arriv-al of the rf signal. The blanking delay is the time which should be allowed toensure that the MOSFET's are correctly biased to allow rf transmission.

RF RISE TIMEThe time taken for an rf pulse to rise from 10% to 90% of its final voltage.

RF FALL TIME:The time taken for an rf pulse to fall from 90% to 10% of its final voltage.

D C RINGINGThis is a consequence of the sharp rise and fall of the blanking pulses (BLKTR1 -15) applied within the amplifier. The ringing will occur at the start and end of theblanking pulse and may last several µseconds. The ringing is independent of therf power.

INPUT NOISE FIGURE:If the amplifier were perfect then noise and signal would both be amplified by thesame factor i.e. the Gain „G“. In reality the amplifier will add it’s own noise to theoutput and the output noise will be greater than Nt x G where „Nt“ is the thermalnoise at the input. The output noise can be represented by Nt x(G + F) where G isthe Gain and F the Noise Figure in dB.

OUTPUT NOISE POWER(UNBLANKED)The thermal noise at 300 K has a power level of - 174 dBm measured over abandwidth of 1Hz. Add to this the 7 dB Noise Figure along with the 54 dB LINEARGAIN to yield an output noise power of - 113 dBm/Hz.

Amplifier Specifications

OUTPUT NOISE POWER:(BLANKED)The blanking will remove the amplification of the final stage of the amplifier as wellas the 1W driver amplifier. There will still inevitably be some crosstalk between thefirst two amplifier stages which in the BLAX 300 RS has a net effect of 20 dB am-plification of the thermal noise when blanked.

INPUT V.S.W.R.A measure of the Voltage Standing Wave Ratio which can be used to quantify theratio of the forward power to reflected power. The typical max. value of 1.3 repre-sents a reflection factor of 13%.

OUTPUT HARMONICS:RF power amplifiers may produce harmonics of the amplified frequency. Harmon-ic levels at the output of the BLAX 300 RS are specified to be at least 20 dB belowthe carrier amplitude. Note: The „c“ in dBc refers to the carrier power which is300W.

AMPLITUDE DROOP:The output of any amplifier may decrease over the duration of a long pulse as aresult of fluctuations in the power supply, input and output impedances, operatingpoint etc. The droop is defined in terms of the percent drop in amplitude comparedto an ideally stable output.

HPPR

TGPPA1, TGPPA2, TGPPA3:These Transmission gating pulses are assigned as follows:

TGPPA1 2H Module

TGPPA2 X BB Module

TGPPA3 1H Module

These pulses are produced by the TCU and may or may not be inverted in theLAB (up to Console wiring ECL04) depending on the HPPR Cover Module config-uration (see section 11.2). As of Console wiring ECL5 the signals are wired di-rectly to the HPPR Periph and the HPPR cover module must be configured foractive low gating.

The module selected as the OBS module is gated by the RGP signal. The TGPPApulses are used to gate any preamps selected to transmit decoupling pulses byacting on the polarization of the diodes in the Transmit/Receive section. Note thatthe TGPPA signals are very often not required. An rf pulse with intensity >1Vpp islikely to bias the diodes even in the absence of a gating pulse.

The pre blanking delay of the TGPPA signals may be adjusted in the „edscon“ ta-ble using the BLKPA[1 -3] parameters.

SPFO:This is the gating pulse for the lock preamplifier. This signal is pulsed at the fre-quency of 6.6 KHz regardless of whether a 2H or 19F lock is being used.

RGP (EP):Normal receiver gating pulse. This signal goes high for the duration of the acquisi-tion. This pulse is used to control the diodes in the preamp module selected as theOBS module. The OBS module is gated separately by the RGP pulse to ensurethat the T/R switching in the HPPR Hot Switch is synchronized with the acquisi-tion. This pulse is connected to the HPPR Periph. from:

the output labelled EP_HPPR of the RX22 (DRX,DPX)

the output labelled EP_HPPR of the RXC (DSX)

the output labelled EPc of the HRD16 Controller II (DMX)

RCP:This signal is not used at present. This signal could be used for fast switching be-tween selected preamps during a pulse program where the RS232C control wouldbe too slow. This would allow the selected OBS module to be switched during anacquisition. This feature may be implemented in the future.


Polarity of gating signals

Figure 11.1. Wiring of Preamp Periphery

Note that the connection to HPPR is one to one.

Polarity of gating signals 11.2

The latest HPPR cover modules (ECL02) allow for the possibility of using gatingsignals which may be active high or active low. Up to now all signals to the HPPRhad to be active high and hence the need to invert the TCU produced signals (ac-tive low) via the LAB2 connection.

A piggyback board (Z4P2996) mounted on the HPPR cover module now allowsthe polarity to be selected with jumpers. Which jumpers correspond to which sig-nal is clearly shown on a label inside the cover module.

Note that

SPPAH = TGPPA1

SPPAX = TGPPA2

SPPAF19 = TGPPA3

Clearly the standard polarity of gating pulses will in future be active low whichwould remove the need for the LAB2 connector. However this board will be contin-ued to be used for the time being as the LAB1 also inverts signals to the SE451and BSMS signals such as Lock Hold and Homospoil.Future systems, fitted withthe new active low SE451 and with modifications to the LCB and SCB of theBSMS, will be so wired as to make the LAB redundant.

1. X-BB/31P 2H stop: This module will transmit up to 31P for all spectrometerranges.

2. X-BB/19F 2H stop: This module will transmit up to 19F for all spectrometerranges.

Module types 1) and 2), are recognized by the HPPR cover display and the „edsp“display (in the earliest UXNMR software versions- up to May 94-) simply as X_BB.

In later software versions it is planned to call them by their full title in the „dsp“ dis-play i.e. either X-BB31P2HS or X-BB19F 2HS.

As a result of the 2H stop filter and the 1H suppression these modules are systemfrequency dependent.

3. A third type of module is the X-BB/19F 2H pass.

This module was previously referred to as a QNP module and is recognized asUSER BOX on the HPPR cover display. In the earliest software versions (up toMay 94), this module was recognized by the „edsp“ display simply as QNP. In lat-er software versions it is planned to call it by the full title X-BB19F 2HP

As a result of the 1H suppression this module is also system frequency depen-dent.

QNP switching 11.4

The switching between the various QNP positions is achieved with two signalsFXA and FXB which are sent from the Backpanel socket BP1 directly to the QNPcontrol module. The signals are generated in the TCU (NMRWord 2 Bits 8,9)

The switching is achieved by setting the QNP parameter in the eda table.

The table below shows the state of Pins BB and FF for the 3 QNP positions.

Preamplifier Selection 11.5

The selection of the correct module as either OBS or Lock preamp is set by soft-ware according to the „edsp“ and „eda“ tables respectively. Note that the previous-ly used PHP parameter which could be used to select the OBS module when achoice was available is now redundant. The HPPR module which is selected asthe destination of the F1 channel in edsp is automatically selected as the OBSmodule.

The eda table contains the parameter HPPRGN which for standard work is set to„normal“. However setting this parameter to „plus“ will switch in an extra 15-17 dBamplifier in the cover display module. This extra amplification might be useful incases where, even using a large value of RG, the signal sent to the digitizer is tooweak. The switching can be checked by measuring the signal „Gain Plus“ at Pin10 of the 14 pin socket J2 of the cover/display module.

HPPR Module Coding 11.7

The types and EC Levels of the modules installed in a particular system must bemade known to the software. This is achieved using jumper settings which areread whenever commands such as „ii“, „zg“ or „gs“ are entered. The jumper cod-ing system is outlined in table 11.5.. The jumpers are located on the Power Sup-ply Board of each module. The first three jumpers are used to define the ECL of

the module. This is an internal ECL determined by jumpers and may not cor-respond with the ECL written at the rear of the module.

Two systems of identification are used depending on the ECL

1) Modules with ECL A or ECL B

2) Modules from ECL C onwards.

From ECL C onwards the system was altered to enable a greater number of mod-ule types to be defined. Note that AVANCE systems is likely only be delivered withECL level C and onwards and this system only will be explained.

Modules from ECL C onwards 11.7.1

Only one set of jumpers, JM1 to JM8 on the Power Supply Board, are used.

Note that the frequency of the Module is no longer included in the coding as wasthe case with ECLA and ECLB.

The first three jumpers are used to define the ECL of the module. The other fivejumpers are used to determine the type of module.

Checking the module identification via the software 11.8

Information on how the software has decoded the jumpers can be obtained as fol-lows:

1. Configure the spectrometer with the command „cf debug“

2. A normal configuration will then proceed.

3. After the configuration is complete enter the command „ii“.

4. After a short delay this will produce a window entitled „ii“ command standardoutput listing. This display contains information about which modules havebeen identified by the software.

The type of Module, the ECL and a hexadecimal code will be given.

The ECL will have numbers 1,2 etc., where 1 corresponds to ECL A in table 1.

The hex code is the binary equivalent of the jumpers settings in table 12.5 withoutthe first three bits, used for ECL determination.

Example of „cf debug“ entryModule 2 = 1H Module ecl 3 code 0x18.

ECL 3 is ECL C of table 11.5.

Jumper settings for 1H in table 11.5. are 00011XXX binary = 24 decimal = 18 hex.

Each time the command „ii“ is entered the debug window will be displayed. If youno longer need this information then reconfigure the spectrometer with the normal„cf“ command.

RX22 Receiver 12

This chapter will highlight the differences between the ARX Receiver and the newDRX Receiver the RX22.

The RX22 Receiver is used in DRX and DPX instruments and is in principle verysimilar to the ARX Receiver in terms of the rf sections. Only minor modificationshave been made to the RF and IF sections. This has resulted principally in a larg-er bandwidth in comparison to the ARX receiver.

A significant modification to the AF section is the introduction of a heater and reg-ulation circuit used to monitor and maintain the temperature of the Quad moduleat a steady of 55°C from ECL03 onwards. (Up to and including ECL02 the Quadmodule temperature was maintained at 65°C). This should further reduce anysmall phase and gain drift that might be caused by temperature fluctuations. Fur-ther improvements are the introduction of improved metal shielding in the Quadmodule.

The RX22 is a cassette-module plugged into the AQR.

Controller module

Apart from performance by far the greatest differences between the ARX22 andthe RX22 is in the controller module which makes software control of hardwarefeatures possible via the RS485 link.

Controller module 12.1

The controller module of the ARX22 receiver was used principally to handle theRG settings, EP pulse and power supplies. The RX22 controller has a muchgreater capability including interfacing with both an RS485 link and an I2C Bus(The I2C Bus is not actually used by the RX22). A Flash EPROM allows the fol-lowing information to be stored:

1) Gain settings for the various rf sections

2) Phase and Gain settings for the Quad module

3) Calibration data for the various amplifiers in the RF, IF, and AF sections

4) BBIS type information

5) Firmware used by the microcontroller

1. Gain settings:

The UXNMR RG value is transmitted to the receiver via the RS485 link. The datais interpreted by the controller and the appropriate control signals are then trans-mitted to the RF and IF amplifiers. The table 12.4. displays which combination of

gain settings is used for the various sections for the complete range of UXNMRRG values. Note that this table uses RG steps of 3 dB. As of ECL00 it is possibleto alter the RG in 1 dB steps.

When an UXNMR RG value which does not correspond exactly to a hardware val-ue is entered, then the nearest value is taken.

Note that whereas before with the ARX receiver it was possible to measure theRG bit settings at the Burndy connector this is no longer possible because the RGbit settings are now transmitted over the RS485 link. However it is now extremelyeasy to test the RG bit settings using the RX22 tool.

2. Phase and Gain settings for the Quad module

It is now possible to make the Quad Image adjustments by software. Using theRX22 tool program the Gain (resolution +3.2% of current Gain) or Phase (resolu-tion + 5°) may be adjusted. When the adjustments are made they should bestored using the „Save Configuration“ routine. This will ensures that the correctvalues are automatically reloaded after a power up.

3. Calibration data:

The calibration of the various amplifiers is carried out in the factory individually foreach board. The increased accuracy resulting from the calibration has made itpossible for the 1 dB steps of the PAS to be implemented. Although this data maybe altered with the aid of the RX22 tool this is not recommended. False calibrationdata will result in the RX22 operating improperly.

4. BBIS data:

The FLASH EPROM also contains BBIS data such as production data, softwareversion, EC level etc. This data is transmitted via the RS485 link.

5. Firmware:

The RX22 tool program can be used to download new firmware.

Downloading Firmware 12.2

When installing UXNMR use the command „rx22_copy“. This will ensure that thenewest firmware contained in the currently installed UXNMR is copied to the ap-propriate files. If this is not done then firmware which is not up to date may bedownloaded.

To download the firmware use Menu Point 3 of the „RX22“ tool.

File to be downloaded /u/conf/instr/rx22tool/tool/rx22.hex

Future RX22 tool versions will have an auto-download feature so that the file pathname need not be explicitly entered.

Reset 12.3

The RX22 Controller is normally active only when the RGP signal is high (inactive,receiver closed). In this state RG values may be changed etc. When the EP signalgoes low (active, receiver open) the controller is effectively switched off. No fur-ther communication is possible over the RS485 link.* The 12MHz mProcessorclocking frequency is also switched off. This ensures that no disturbances can oc-

cur during the acquisition. When the EP goes high again the controller is effective-ly reset and once again operational.

*Two exceptions to this are

a) the special mode activated within the RX22 Tool under the menu point„Debug EP_Blank“. This allows Gain and Phase adjustments to be madeover the RS485 link even during acquisition.

b) gs mode operation.

I2C Bus: The Controller interfaces with the I2C Bus of the back panel. The RCU is masterof the 4 slots of the receiver section

Jumper Settings, Polarity of RGP(EP) 12.4

As of ECL01 it is possible to set the polarity of RGP(EP) output signals usingJumpers on the RX22 and RXC. Note that the RX22 and RXC are active low de-vices i.e. they use an RGP input that is low when the Receiver is open. Howeverthey also use this input to generate EP outputs used elsewhere in the spectrome-ter. The Table below shows the assignment of J19 and J20 for active high/low out-puts. Note that active high means high during acquisition.

The figure 12.2. below and figure 12.3. show the jumper settings which corre-spond to the two possible configurations.

Power Supply 12.5

The RX22 receives the required power from the AQR Mainframe and can easilybe measured using the Test Extension Board (P/N Z012746). The following tableshows the test points and corresponding signals.

Image Rejection Mixer 12.6

As a result of the relatively low Intermediate Frequency (22 MHz) the RX22 usesan image rejection mixer to remove unwanted folded noise that might be transmit-ted through the XBB preamplifier.

Consider the case of 13C OBS on a 300 MHz spectrometer. For a received signalof 75 MHz the signal is mixed with an LO of 97 MHz to produce an IF of 22 MHz.

However noise at 119 MHz, when mixed with the LO, would also produce an IF of22 MHz and hence the need for the image rejection mixer. The rejection mixertransmits signals at LO-22MHz (75 MHz in above example) and attenuates bymore than 20 dB noise at LO+22 MHz (119 MHz in above example).

The mixer works for frequencies up to 600 MHz approx. Any stray frequenciesabove this value would be outside the X frequency range and will be removed bythe filters in the 1H HPPR module.

Testing the overall gain of the Receiver

Testing the overall gain of the Receiver 12.7

Column 2 of table 12.4. lists the approximate overall real gain of the RX22 Re-ceiver for a range of RG values. To check these values carry out the following pro-cedure.

1. Measure the voltage of the 80 MHz output of the PTS620 (~1Vpp at 50 Ω)

2. Set SFO1 = 80.0001 MHz. AQ = 60 seconds

3. Set RG = 1

4. Connect the 80 MHz output via a variable attenuator to the receiver input. Setthe attenuator to 80 dB.

5. Enter „zg“ and observe the voltage at the receiver output CHA or CHB. Adjustthe variable attenuator until the voltage at the receiver output is equal to thatmeasured at the 80 MHz output of the PTS. The attenuation required can betaken as a measure of the gain of the receiver.

You can repeat using various values of RG, but be sure to increase the attenua-tion accordingly.

HRD 16 Controller Board 13

The HRD 16 digitizers as used in AVANCE spectrometers have a modified Con-troller Board II (P/N Z02478)

Functions 13.1

1. To provide RGPa, RGPb and RGPc outputs.

These three outputs (labelled EPa, EPb, EPc on the board itself) are identi-cal and generated from a single RGP pulse transmitted from the RCU viathe 50 way digitizer cable.

In a DMX, 2 of these outputs are used in the SE451 (RFT and LO), the thirdis used to blank the OBS module of the HPPR. As such the three outputsare active high (i.e. high during acquisition).

In a DRX, fitted with HRD 16 as option, only the RGPa output is required.This output is connected to the LAB1 where it is inverted (to active low dur-ing acquisition) and transmitted to the RX22 via the AQR backplane. Fromthis signal the EP_ HPPR output (active high during acquisition) is alsogenerated (see figure 13.2.).

2. To provide an ADC ON output

This signal is generated by the RCU and transmitted to the HRD 16 via the50 way cable. The signal as well as controlling the ADC of the HRD16 itself,is required to control the ADC LED of the BSMS keyboard. A modification(EC no. 1865, see APPENDIX) may be required with earlier LAB's in orderto observe this LED on the BSMS keyboard. The ADC ON signal is simplywired through the LAB to the AQR backplane. It is not inverted on the LAB.From here it is transmitted to the BSMS via the ACB.

Future AVANCE spectrometers will be fitted with the HADC (instead of theHRD16) which will have direct access to the AQR backplane and the LABwill not be required (The spectrometer must also be fitted with an RXC andthe new 19 inch SE451).

3. Transmission of bits DRG 0 - 7 to SE451 via the canon mini sub 9.

These signals are actually generated by the RCU and simply transmitted tothe HRD16 via the 50 way digitizer cable. The Bit settings can easily bechecked either at the HRD16 output or at the RFT Burndy of the SE451(ta-ble 13.1.).

Note that bits DRG 0 - 5 are used to set the receiver gain in the SE 451 from 1 to32K. DRG 7 is used to switch the High Pass / Low Pass filters in the RFT. Bit 6 isnot used. For DRX spectrometers the sub mini 9 connector is not required. Thereceiver gain is set via the RS485 link to the RX22.


HRD 16 Controller Board

Two final functions of the Controller II board have not changed. Transmission ofthe digitized signal and setting of the analogue filters.

Note however that since the HRD16 will normally be operated at minimum dwelltime (2.5 µs) a single filter setting (SWH=250K i.e. FW=312K) is all that is re-quired. Changing the SWH will not alter the DW and so the filter setting will notchange.

RCU: Receiver Control Unit 14

Functions 14.1

1. Upon receipt of the RCUGO signal from the TCU, the RCU takes completecontrol of the acquisition. The RCU will then operate autonomously until theend of the current scan. To perform a second scan however the RCU must waitfor a second RCUGO signal from the TCU

Note that the RCUGO signal is synchronized with the 40MHz in signal, bothof which are received from the TCU. It is important that both these signalsare derived from the same source.

2. As part of the acquisition control the RCU generates the DWELL CLOCK aswell as the RGP and ADCON signals. It also handles the receiver phase.

3. The RCU is responsible for processing the acquired signal i.e. digital filteringand decimation as well as accumulation and the DMA transfer of processeddata to the CCU.

4. The RCU is master of all digitizers (SADC, HADC, FADC and HRD16) and alldigitizer functions. T. This includes the filter settings (SADC, HADC, FLTP/4Mand HRD16FT) and Quad. Mode (qsim, qf). For the SADC, HADC and HRD16the information is sent directly over the 50 way digitizer cable. For the FLTP/4M the information is sent through the SADC or HADC and then to the FLTP/4M via the I2C BUS of the AQR.

5. For homo-decoupling the timing of the decoupling pulses is set by the RCU.The RCU generates two signals SPHD and RGP (EPHDON EPHDOFF SPH-DON SPHDOFF). These signals are then combined in a PAL (TCU0AE40) onthe TCU to synchronize the receiver gating with the decoupling pulses.

6. Setting of the SE451 receiver gain in DMX and DSX spectrometers. In DMXspectrometers the RG bit settings are first ported through the HRD16 Control-ler II Board and then connected to the SE451 via the 9 way cable. In DSXspectrometers the RG bit settings are transmitted to the RXC from the CCUover the RS485 link and then connected to the SE451 via the RXC front panelconnection.

Future machines will no longer be fitted with the HRD16 and the RG will al-ways be set with the RXC.


RCU: Receiver Control Unit

Front Panel Connections 14.2

40 MHz in:This input signal is used to clock the RCU and thereby generate the Dwell clockand homo-decoupling timing. It is TTL (3 Vpp at 50W) and normally operates on a50% duty cycle.

RCUGO in:The acquisition is prepared first by the software. The RCU will not perform any ac-tions until it receives the RCUGO command from the TCU. This pulse must ac-company every scan and must be synchronized with the 40MHz in signal. Thetiming is so that it goes high for 50 ns, approximately 200 ns before the RGPpulse.

40MHz out:This output is normally not connected but can be used for test purposes.

RCUGO out:This output is normally not connected but can be used for test purposes

EXT.DWCLK:In normal operation this input is not connected. However it may be possible toprogram the RCU to operate on an external clock from the TCU as opposed to theinternally generated clock.

EXT.EP:In normal operation this input is not connected. It has been provided so that thereceiver gating could be synchronized with an external pulse from the TCU.

50 way digitizer cable: As well as the normal digitized FID the 50 way digitizer cable also transmits theADCON,RGP and I2C bus signals.

The SCI connection is an RS485 type connection which is used for debuggingpurposes and so normally not used.


Checking the DWELL CLOCK

Figure 14.1. RCU Front Panel

Checking the DWELL CLOCK 14.3

For this the Test Extension Board (P/N H2066) is required. The DWELL CLOCKsignal may be measured at J2 C30 of either the RCU or the TCU.

If the Test Extension Board is not available then the DWELL CLOCK can be mea-sured at C30 of the Acquisition Bus along the back of the AQX32.

The following table illustrates the Min. dwell time and corresponding max. dwellclock for various digitizers.

Note that for the FADC the oversampling is redundant at rates above the normalmode.

Note also that the actual dwell clock is determined not by the parameter DW(„eda“) but rather DWOV.

Acquisition Bus 14.4

The RCU is connected to the TCU via the Acquisition bus. The TCU is the oneand only master of this bus. Typical instructions sent from the TCU to the RCUover this bus are:

a) RCU Ze = zero memory

b) RCU SYNC = synchronize the RCU clock (40 MHz) with the TCU clock(80 MHz)

c) RCU_PH 0 = set receiver phase

d) RCU EOA = end of Acquisition

e) WR#0 = write to disc

The above commands can be checked using the file „shm.out“ which is automati-cally created in the users home directory with the command „gotst“.

Note that the Acquisition Bus is not used to transmit the RCUGO signal and 40MHz clocking frequency. Instead they are sent directly to the RCU over the frontpanel as it was felt that this would lead to cleaner signal transmission.

VME Bus 14.5

The RCU is connected to the standard VME bus which runs along the AQX32backplane. The CCU and RCU are the only possible masters of this bus, with theRCU having priority. Typical uses of this bus are:

a) Transfer of processed digitized data from the RCU to the CCU (DMA).

b) Transfer of information regarding the Filter Widths, Receiver Gains asset by UXNMR.

c) Upgrading of acquisition parameters e.g. number of scans, etc.

Transfer of data to CCU 14.6

The RCU operates an automatic overflow and diskwrite. The accumulated digi-tized FIDs are stored in a 32 bit x1 M DRAM. The number of scans that can bestored will depend on the digital resolution that is used (see figure 14.2.). Notethat the RCU can be fitted with optional extra DRAM expanding the memory to 32bit x2 M DRAM

At higher sample rates, when using the FADC, a 32 bit x 64K SRAM which is fast-er than the DRAM is used for accumulation.The use of the SRAM is automaticallyhandled by the software

Diagnostic test 14.7

The RCU may be checked using

/u/systest/rcu/rcutest (logged in on spect)

Useful commands are

„h“ = help and prints a list of commands

„res“ = performs a software reset of the RCU

„auto“ = starts an automatic self test

The directory /u/systest/rcu also contains the file „docu“ which describes the „rcut-est“ commands in detail.

12C Bus in the AQR 15

BBIS 15.1

This term stands for Bruker Board Information System and is a component of theon-board local intelligence which is now a feature of all AQR boards. In the futureit will be expanded to include the AQX32 boards. The system is designed to storeinformation about a particular board on the board itself in an EEPROM. The typeof information stored is Date of manufacture, Part and Serial number, EngineeringLevel etc. This information is burnt onto the EEPROM at manufacture. At the mo-ment it is only possible to access this information using a P.C. and special soft-ware. However it is envisaged that in the future engineers will be able to accessthis information via a service tool. When the system is fully implemented it shouldbe possible to login remotely to a customer’s spectrometer and have access to in-formation such as the Engineering Level of all boards. The transfer of informationwithin the AQR boards is achieved using the I2C Bus.

I2C Bus 15.2

This is a bi-directional, real time 8 bit serial bus. The bus is non differential anduses TTL levels. Two independent I2C buses run along the AQR backplane (seefigure 16.1). Although both buses use the same protocol they perform differentfunctions and shall be described separately.

Note: In order to separate the two I2C buses of the backplane jumpers JU1, JU2,JU3 and JU4 must not be populated.

I2C Bus 1 15.3

This bus interconnects a maximum of eight slots of the AQR Backplane and isused exclusively to support the BBIS. The ACB is the one and only master of thisbus. This essentially fixes the position of the ACB in the AQR. The eighth slaveshave hardware addresses 0 - 7. The address of a particular slot is fixed in that it ishardwired at the backplane. Vacant slots do not interrupt the bus. An ASU can beplaced in any of the slots corresponding to Address 4, 5 or 6. Similarly a routercan occupy Address 1, 2 or 3.

The lines of the I2C bus are as follows:

SDA:This is the serial data transfer line. Data may only be sent in 8 bit words. For ad-dressing purposes the 8 bits are subdivided as follows:


12C Bus in the AQR

Three bits determine which board is to be addressed. This limits the bus to a max-imum of eight boards. Four bits determine which chip of the board is addressed.For I2C Bus 1 this address must always correspond to the EEPROM which storesthe BBIS data. The last bit determines whether the bus is operating in read orwrite mode.

SCL:The I2C bus can operate at various clocking frequencies as set by the master. TheACB Board uses a clocking frequency of 100 KHz which is the maximum for I2Cbus operation.

SDIR:The SDIR Signal determines whether the master ACB is sending data (SDIR low)or receiving data (SDIR high).

The 8 bit data words mean that each BBIS EEPROM contains a maximum of 256storage registers, each containing up to 8 bits of data.

II2C Bus 2 15.4

A second I2C bus interconnects the remaining three slots. For DRX Spectrome-ters the slots are occupied by the RX22*, LAB and SADC. For DMX Spectrome-ters only the LAB slot is occupied. For DSX Spectrometers the three slots areoccupied by the RXC, FLT/4P and SADC (see figure 16.2).

The master of this I2C bus is the RCU. Access to the bus is gained via the SADCusing the 50 way digitizer cable. The I2C bus can be used to:

a) Support the BBIS as with I2C Bus 1.

b) Set the filters in the SADC (DRX).

c) Set the filters in the FLTP/4M (DSX).

d) Turn the quadrature detection off (qf in eda).

The software hex. addresses for these boards starting at far left (SADC) are 4E,4C and 4A.

* Note that while the RX22 has access to the second I2C it does not use it.


DSX Configuration:

DSX Configuration: 15.5

The figure 15.2. shows the standard configuration of a DSX. The following is abrief outline of the functions of the various boards.

SADC:This standard DRX board is fitted so as to give the RCU access to the AQR back-plane. In this way filters in the FLTP/4M can be set. Furthermore the customer hasthe option of using the SADC which has a higher resolution than the FADC.

12C Bus in the AQR

FLTP/4M:This is the filter board so named because of the max. Bandwidth of 4MHz. The fil-ters are set by the RCU via the I2C bus. This board also provides the power sup-ply for the FADC

RXC:This is effectively an RX22 minus the RF section. The DSX is fitted with an FADCinstead of the HRD16. The RXC board in a DSX fulfills the functions of the HRD16Controller II Board in a DMX. This board receives the RGP(EP) from the RCU viathe SADC and AQR backplane. This gating pulse is then used to produce threeoutputs RGPa, RGPb and RGPc. These three outputs (labelled EPA_SE451,EPB_SE451 and EP_HPPR on the board itself) are identical.

A second function is to set the RG bits for the SE451. The information is transmit-ted via the RS485 link from the CCU

A future function of the RXC will be BBIS identification of the new SE451. This willbe done via a direct I2C link from the RXC front panel to the SE451.

ACB 16

The ACB acts in may ways as an interface between various spectrometer unitsand shall be discussed in terms of the various communication links with theseunits (see figure 16.1.).

SBS Bus 16.1

The ACB can control up to a maximum of 16 linear amplifiers via the SBS (SerialBruker Spectrospin) Bus. This is an RS485 type bus of which the ACB is the oneand only master. The ACB uses the bus to determine the type and number of in-stalled amplifiers. Each amplifier housing is given a unique address via a Hex.switch on the amplifier front panel. From the Hex. address the router outputs towhich the amplifier is connected is made known to the software. This informationis then used to customize the „edsp“ display for each individual spectrometer.

Amplifier parameters such a Max. Duty Cycle, Max Pulse Width etc. may also beaccessed via the SBS Bus.

This bus also carries the „FORW“, „REFL“ and „BLKTR“ signals from the Amplifi-ers to the ACB. From here these signals are displayed either on the graphic mon-itor or on the BOSS keyboard.

Note: For correct operation the SBS Bus cable (P/N H5624) must be fitted withthe terminating plug (P/N H5167).

RS232 Connection 16.2

This connection is used:

1. During initial ACB start-up/reset and to transmit amplifier status and parame-ters to the CCU.

2. To transmit the data for the screen display of forward and reflected power etc.The data is transmitted to the CCU and then displayed on the graphics moni-tor. Only those amplifiers which are required for the power display are scannedby the ACB.

3. Read/Write BBIS data via a software tool. This tool is still in development but itwill soon be possible to access all BBIS data of the 8 AQR boards connectedto the ACB via the I2C bus.


ACB

Figure 16.1. ACB Interfaces

I2C Bus 16.3

The ACB is master of the I2C Bus which interconnects 8 slots in the AQR. The ad-dressing of various boards is determined solely by the position of the slot in theAQR. The position of the ACB in the AQR is fixed to the second slot from the end.The position of other boards is more flexible i.e. a Router can occupy any Routerslot, an ASU any ASU slot etc. The I2C Bus is used to transfer BBIS data.

Link to BSMS

Link to BSMS 16.4

This is a 40 Bit unidirectional data stream used to operate the power display onthe Boss keyboard (one bit for each LED). The information is received from theamplifiers via the SBS Bus. The power display has a refresh rate of between 300and 600 Hz. depending on the number of amplifiers that are scanned.

This connection also carries the ADC ON (from AQR Backpanel) and OBS (fromComputer) signals to the Boss Keyboard.

Then final function of this link is the „Chan Select“ and „TRANS P-DOWN“ func-tions.

The „TRANS P-DOWN“ button on the BOSS keyboard will cause the ACB to setthe SPENAB signal high when pressed. This will disable all ASU’s, Routers andAmplifiers.

The „Chan Select“ button on the Boss Keyboard simply causes the ACB to togglethrough the various channels with regard to the power display.

Note: If the cable to the BSMS CPU is not attached all signal transmission is auto-matically disabled.

Reset 16.5

This will:

a) reactivate the SPENAB signal.

b) re-enable any disabled amplifiers.

A hardware reset is carried out by pressing the reset button on the front panel.

A software reset is carried out during the „cf“ routine or by clicking on „ACB-Re-set“ in the „acbdisp“ menu.

LAB: Level Adapter Board 17

This board is used to invert signals from active low (AVANCE standard) to activehigh. This is required for units such as the SE451 and HPPR which were devel-oped prior to the introduction of the AVANCE series.

Note: Newly developed SE451 units and HPPR cover modules will make the LABredundant. In the case of the SE451 the logic will be altered to active low. Thenewest HPPR cover modules have a piggyback board with which the HPPR canbe configured to accept active low gating pulses. Modifications to the BSMS willalso enable the LockHold and Homospoil outputs to be inverted by software.

The LAB has two connectors LAB1 and LAB2.

LOWER CONNECTOR LAB1 17.1

The functions of the main LAB board which takes it's inputs from Connector LAB1will depend on whether the instrument is a DMX or DRX. Jumper settings can beused to determine

a) whether a signal is inverted or not

b) whether a signal is connected to the AQR backplane or not.

STANDARD DMXThe board is used to invert signals used in the SE451. Listed below are the rele-vant signals and required jumper settings.

To invert TGPCH1 (SPFX to SE451) J6 in

To invert TGPCH2 (SPFH to SE451) J5 in

To invert OBSCH1 (SELOBS X/H) J2 in

STANDARD DRXFor a DRX fitted with a RX22 receiver the Connector LAB1 is not used. This is be-cause the RX22 logic is active low. Note however that one jumper position is rele-vant. Jumper J9 should not be inserted. This is to ensure that the RGP pulsewhich is transmitted along the AQR backplane is not connected to the LAB.

DRX with HRD16:The RGPa pulse is normally transmitted from the RCU to the SADC via the 50way digitizer cable. From here it is connected to the RX22 via the AQR backplane.When the SADC is not fitted then the HRD16 must provide the RX22 with RGPa.A cable connects RGPa out (SMB connector of the HRD16) to pin P of Connector


LAB: Level Adapter Board

LAB 1 (see figure 13.2.). From here it is inverted and transmitted to the back-plane. The required jumper settings are listed below:

To invert RGPa (EPa) J7 in

To connect RGPa (EPa) to backplane J9 in

BSMS Signals:Two further signals may be inverted if required using Connector LAB 1:

UPPER CONNECTOR LAB2 17.2

The piggyback board handles signals received from Connector LAB2 and is nor-mally used to invert signals for the HPPR. Three inputs (TGPPA1, TGPPA2, andTGPPA3) are taken from the TCU and the inverted outputs are connected to thePREAMP PERIPH Connector.

The piggyback board is designed to invert any connected inputs. There are nojumper settings to determine whether a signal is inverted or not. The board isused identically in DMX, DRX, and DSX spectrometers.

DPX Spectrometers 17.3

For these spectrometers the LAB is not required because

a) The RX22 logic is active low. This makes Connector LAB1 redundant.

b) They are fitted with the newer HPPR cover modules as standard. Thismakes Connector LAB2 redundant.

Note that for some of the earliest DPX spectrometers it may be necessary to mod-ify the BSMS for Lockhold inversion.

Software 18

EDSCON: Edit spectrometer constants: 18.1

It is now possible to edit the delays before rf pulses using the table called up withthe UXNMR command „edscon“. Note that the edscon table does not allow one tomake all adjustments that are supported by the hardware. Instead a simplifiedversion has been developed in the interest of user friendliness. The engineershould however be aware that the pre and post blanking delay may be set individ-ually for every individually produced TCU output. In the edscon table the user canset the pre blanking delays only. To set the post blanking delays, with the softwareas it is presently configured, would require explicit pulse programming. A furthersimplifying feature is that the same timing is used for Router, amplifiers andASU’s. However with explicit pulse programming these could also be set individu-ally. If deemed necessary the edscon table could be expanded to support all hard-ware timing features.

The constants set in the „edscon“ table are stored in the file /u/conf/instr/<name>/scon

The constants are set for the spectrometer and will automatically be implementedfor each new acquisition. Individual values may not be stored in different datasets. Figure 19.1 shows the relationship between the „edscon“ parameters andthe corresponding blanking pulses for an rf pulse of length p1 on channel 1. Allvalues are in ms.

Default values for all preblanking is 3ms. The BLKTR,TGPCH,TGPPA and BPCHpulses have already been explained in various chapters. Note that while the tabledisplays BLKTR0-15 only BLKTR1-15 are relevant as regards amplifier and routerblanking. Furthermore as regard the ASU only BLKTR1-8 are actually used. ThePHASPR parameter is the phase preset time which can be set individually foreach FCU.

The software is so programmed that 4.5ms after the „go = 2“ statement in thepulse program the first point will be digitised. This value can be changed but onlyin the source program. However at what particular point within this 4.5ms the Re-ceiver is opened may be set by the user with the parameter De1. This has the de-fault value of 2ms. A second parameter De2 which determines how soon after theRCU_Go pulse the transmitter phase is reset may be adjusted with the parameterDe1 (default value 1ms).


Software

EDSP display 18.2

One of the most impressive new features of the AVANCE series is the „edsp“ dis-play. This allows the user to define the experiment details in a user friendly way.The edsp menu is implemented using several new parameters which will now beexplained. Note that all these parameters are set most conveniently using themouse and the values are normally hidden from the user. They can also howeverbe entered or checked from the keyboard.

FCUCHAN:This parameter determines which physical FCU is assigned to which softwarechannel. This parameter can be set by hand using the following notation:

0 FCUCHAN 3= 4*

Which means that FCU number 4 will be used for the logical channel F3.

0 FCUCHAN 4= 5

Which means that FCU number 5 will be used for the logical channel F4 etc.

* Note that the keyboard syntax is „0 space FCUCHAN space 3 enter “ etc. Thissyntax applies to all edsp parameters.

The default FCUCHAN values can easily be restored by clicking on „DEFAULT“with the mouse.

RSEL:How a particular signal is routed is determined by the setting of the RSEL controlwords. Since each FCU is effectively hardwired (via the PTS) to a specific Routerinput and each Router output is hardwired to a specific amplifier, the edsp displaysimply displays the FCU connections to the amplifier.

The routing of FCU1 is determined by the value of RSEL1, the routing of FCU2 isdetermined by RSEL2 etc. The destination amplifier determines the value as-signed to RSEL1, RSEL2 etc.

For example:

0 RSEL1 = 3 means that FCU1 is routed to amplifier 3

0 RSEL2 = 5 means that FCU2 is routed to amplifier 5

Each amplifier is numbered from 1 to 16 as in figure 18.2..

Where a router input is not used then the corresponding RSEL word is assigned avalue of 0.

SWIBOX:The output of the various individual amplifiers may be switched to different N-typeoutputs labelled 1H, 19F and X QNP on the amplifier housing front panel (seechapter 11).

The parameter SWIBOX is used to control the internal switching within the ampli-fier housing. The amplifier outputs can be switched to different N-type outputs de-pending upon the value assigned to the SWIBOX parameter.

For example: 0 SWIBOX 1 = 3 means switch amplifier output 1 to N-type output 3

The numbering of the various inputs and outputs of the DMX and DRX standardamplifiers can be seen in figure 18.2. and figure 18.3.

Where an amplifier output is not used then the corresponding SWIBOX word isassigned a value of 0.

Note that in order for the edsp display to work properly the output of the firstBLAX300 in a DMX should be hardwired to the Xin of the BLARH100.

PRECHAN:This parameter is used to determine the connections from the amplifier output tothe HPPR module. Note however that this parameter has no physical influence It


Software

is up to the operator to ensure that the cabling is correct. The parameter is re-quired so that the contents of the edsp display may be stored and called up at alater date. The PRECHAN parameter is however used to determine the OBSmodule. The module chosen as the destination of the F1 (NUC1) channel will beselected as the OBS module.

Up to 5 HPPR modules may be displayed in edsp and they are numbered 0 to 4as in figure 18.2.

For example: 0 prechan 1 = 3 means that amplifier output 1 is connected to HPPRmodule 3.

Note that when an amplifier output is not used then the corresponding PRECHANparameter defaults to a value of 5.
