1. Introduction

NI386X with tuner, ISDB-T demodulator and IF output for analogue TV

The NI386X is an ISDB-T NIM. It is intended for the Brazil market.

With the evaluation kit it is possible to demonstrate the function and the performance of the

NI386X for ISDB-T reception. An additional test board option is an analogue demodulator todemonstrate the function and the performance in analogue TV mode.

First the evaluation software must be installed. After that the hardware can be connected.

4. Operation

Test board with NI386X for ISDB-T with option for analogue TV reception

4.1 ISDB-T mode

Jumper BA10: Connection between jumper pins 3 and 4

Jumper BA11: Open

Connect RF ISDB-T signal to the antenna connector 1

Connect the IC bus interface with connector 10 and the computer parallel port(LPT1)

Connect 6,5V DC to power supply connector 11 (Power on LED at the testboard is on)

Reset the module with key 8

Start the software with a double click at the shortcut on the desktop (The panelon the next page appears)

Select the required frequency

The demodulator is locking (no red indicators, Lock LED at the test board ison)

If required a picture test can be done. Connect the monitor equipment with theLVDS-connector 9.

The ERROR LED on the test board is an indicator for uncorrectable packeterrors

5V Antenna power can be provided if the antenna power jumper is in on-position (Be careful, this feature can damage your measurement equipment)

4.2 Analogue TV mode

There is an analogue demodulator test board option to provide very efficient analogue

reception investigations.

Jumper BA10: Connection between jumper pins 3 and 4

Jumper BA11: Set

Connect RF analogue TV signal (Standard M or standard N) to the antennaconnector 1

Connect an TV with an CVBS-video input to the connector 4 Connect the IC bus interface with connector 10 and the computer parallel port

(LPT1) Connect 6,5V DC to power supply connector 11 (Power on LED at the test

board is on) Reset the module with key 8

Start the software Deselect the check box Digitalin the tuner window (Analogappears instead of

Digitaland the digital demodulator window disappears)

Press the reset button in the software

Select the required frequency or the required channel

No indicator in the software should be red

The transmitted picture should appear on the screen

A mono audio signal is provided at connector 6

A Sound IF signal is provided at connector 5

5V Antenna power can be provided if the antenna power jumper is in on-position (Be careful, this feature can damage your measurement equipment)

Depending on the jumper position (BA10) the analogue demodulator can besupplied with an external IF signal 3 or the analogue IF can be monitored

5. Software features

5.1 ISDB-T demodulator control

Lock: Green color indicates that an

ISDB-T signal has been detected

Demod Address: The demodulator IC

address can be selected depending on

the ADR0 (Pin 30) and ADR1 (Pin 31)

Mode: FFT size, Mode 3 = 8k FFT,

Mode 2 = 4k FFT and Mode 1 = 2k FFT

Guard: Detected guard interval

Emergency: Becomes red when

emergency signal is detected

Reset emergency: Press this button to

reset the XIRQ output into non

emergency state. Otherwise the XIRQ

output remains in emergency state

Transmission parameters:

Modulation, Code rate, Time interleaver

mode, Number of segments for each

layer

BER: Bit error rate pre Viterbi, after

Viterbi and detected packet errors

SNR: Signal to noise estimator

By clicking in the Post Viterby field Layer

A , B or C a additional window comes up

and show the post viterby and package

error over time in a display


11/16


24/04/09


Thin blue line: Show post viterby

errors over the time.

Fat red line: Show packet errors

Fat orange line: limit for post viterby

errors. Could be changed through the

numeric control in the panel)

5.1.1 IQ, BER, MER Setting

Application Digital Demodulator IQ, BER, MER Setting

IQ: Switches between normal mode and

spectrum inversion

RS: Reed Solomon decoder state

Segment: Switches between different 1 and 13

segment reception

BER Monitor Timer Setting: Number of data

for BER calculation

5.1.2 TS Output Setting

Application Digital Demodulator TS Output Setting

Sets the parameters for the digital transport

stream interface

5.2 Tuner control

5.2.1 Tuner standard mode

Load: A frequency table in tab separated format

can be loaded. It is possible do modify this table

with a text editor.

Frequency: The required RF can be set. For

ISDB-T it is the channel center and analogue

reception it is the picture carrier frequency. If the

channel table is used the frequency of the

selected channel is displayed.

IF frequency: Displays the IF. For digital

reception it is the channel center and for

analogue reception the picture carrier

frequency.

Stepsize: This value represents the reference frequency. The default value is

recommended.

Stepsize Large: Adjusts the step size for the arrows of the frequency input box. If Offis set

the smallest step size is used (Reference frequency).

AGC Threshold: This value represents the level at the IF detector when the RF-AGC starts

to control. The default value is recommended.

LOW/MID/HIGH: Indicators for the used tuner band

Reception: Switches between analogue and digital reception. For analogue reception the

ISDB-T demodulator is in stand by mode.

I2C-Bus indicators: Shows the status of the tuner IC bus. No indicator should be red.

5.2.2 Tuner expert mode

Application Tuner Expert

These settings should be changed only by experienced users. It can deteriorate the tuner

performance. In the expert mode the charge pumps will not be set automatically.

Charge pump: Manual charge pump control

Band / Standby: Manual band switch and tuner stand by

AGC Decay Current: Changes the time constant of the RF-AGC (Only for ISDB-T reception)

5.3 IC interface

IC Status: No indicator should be red. The IC speed can be changed

with the slider.

I/O Port: The parallel port address (LPT-Port) can be selected. In most

cases 0x378 is the right value.
