SECTION 7 – IMAGE SPATIAL RESOLUTION
7-1 DESCRIPTION
MTR Survey Program
Image spatial resolution can be measured by scanning a GE Performance Phantom and analyzing the acquired imagewith the MTF Survey program included in Support within the Maintenance menu.
The MTF Survey program calculates MTF data by the two–dimensional Fourier Transform of the point spread functionusing pixel data around the wire.Since the program stores the result to a mean file, analyze the result using Support display, and evaluate the systemspatial resolution performance.
The following section describes the procedure for this spatial resolution evaluation using MTF Survey.

SECTION 1 – POWER UP SEQUENCE
1-1 OVERVIEW (INCLUDE: READING HEXA–DECIMAL LED ST ATUS). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
The Power–ON test program is used for OC self–diagnostics during the Power up sequence, and is resident in theROM on the CPW assy.
This test program has two categories: Power On Test 1 (P–ON1) and Power On Test 2 (P–ON2).The P–ON Test 2 includes more detailed tests than P–ON Test 1, and takes longer to run. P–ON Test 1 is normally selected during routine customer operation. P–ON Test 2 can be used by the field engineerto perform a more detailed analysis in the event of an error occurring on the system.
During test execution, the test currently running, along with the description/name and status (pass/fail), are identifiedin 2 or 3 ways depending on the test concerned as follows:
1. CPW LEDs (all tests)
2. CRT display monitor (all tests, except CPW Phase 1, and DISP Phase 1 tests)
3. Terminal connected to CPW RS232C output (all tests)
See Section 1-2 for more details.
If at any point during the P–ON Tests an error is encountered, the testing is halted and the failed test number/coderemains on the CPW LEDs. With the exception of CPW Phase 1 and DISP Phase 1 tests, the test name/descriptionwill also be displayed on the CRT monitor along with a brief error description.
NoteThere normally no need to connect a CPW RS232C terminal, since no additional information otherthan that on the LEDs and monitor can be obtained during P–ON Tests. Connecting a terminal is onlynecessary for the execution of the off line tests.
The total processing time is as follows:
Table 1–1 Test Processing T ime

1-1 OVERVIEW (continued)
Reading Hexa–decimal Numbers from LEDs
The hexa–decimal number in each rectangle herein represents the LED status displayed on the CPW board. Readthe LEDs from top to bottom (MSB to LSB). Decode the top four LEDs to create the most significant hex digit (theleftmost digit) and the bottom four to create the least significant hex digit (the rightmost digit). All hexa–decimal codesare displayed with the letter ‘H’.
More detailed status and information is displayed on the CRT from CPW Phase 2 test, so it is normally not necessaryto decode the LEDs status.
Example:
87654321
bit 8 7 6 5 4 3 2 1 (LSB)
1 0 0 1 0 0 0 0 (90H)
‘�’ means ‘Illuminated’ and equals ‘1’: ‘�’ equals ‘0’. LEDs are set at the start of each routine. If any error occurs duringself–testing, the LEDs display the corresponding error code.

X: Don’t Care. The following parameters are set by default witheach speed setting and cannot be cancelled;–
1. Character length = 8 bits2. Stop Bit = 1 bit3. Party = None
The DIP SW setting information is read at the moment of system power up or reset. Changing the DIP switch settingduring test execution will have no effect on the test sequence. If you want to change the parameters, first set the DIPSW accordingly, then press the OC reset switch to start the test.
NoteThis test program does not write any data to the HD, but it does require a properly formatted HD.i.e.: The tests will run with a normal operational HD, but not with an unformatted replacement HD.

1-5 CRASH SAVE AREA
When abnormal termination is caused by any failure (Bus Error, Address Error, or OS task crash), error informationis stored into an area of Memory called the ‘Crash Save Area’. Each processor has a Crash Save Area.
The Crash Save Area contains the following information:
Program Counter Status Register at crashOther registers LED status
For details, see illustration 1–3.
The Crash Save Area on each processor is saved onto the hard disk at power–on. You can also save this informationonto floppy diskette as shown in illustration 1–4. Use the following procedure to transfer Crash Save Area informationto floppy diskette.
Under crash condition:
1. Label a crash save floppy diskette and insert it into the floppy disk drive.
NoteThe first time you use this diskette, initialize it for a crash save according to Appendix A, How to MakeCrash Save disk.
2. Pull the system reset switch with the diskette in place to automatically transfer a copy of the crash save areaof each processor onto the diskette. The system rest switch is located beneath OC keyboard console extension.
3. Use the following procedure to read the contents of the diskette.
a. Insert the BOOT diskette into the floppy disk drive.
b. Set the BOOT select switch on the CPW board to the following positions:

2-1-1 Overview
The off–line tests for diagnosing each of the following electronic boards and some components (Hard disk drive, AudioAssy, etc.) installed within the Operator Console are provided on each separate floppy diskettes.
� CPW
� MISC (and TPC)
� DISP
� IPU
� SBPU
The off–line tests for MISC include communication tests between CPW and the processor equipped within the Gantry.
The off–line tests perform more extensive diagnostics than the on–line tests described in the previous section.The off–line tests report which device or operation is the cause of a system or information system failure.
The off–line tests except for the CPW board are provided on floppy diskettes. The off–line test for the CPW boardis provided on the ROM on the CPW board. The off–line tests are interactive ones, requiring an external display termi-nal.
The test proceedings or error information occurred during the test execution are shown on the CPW status LEDs aswell as on the display. The status LEDs turn off when all the off–line tests have been finished without an error.
Illustration 2–1 shows the general flow of the off–line tests except the ETC off–line test.

The ETC (DC–X Ethernet Controller Interface) Power–ON Test program is used for ETC self–diagnostics during thePower up sequence, and is resident in the ROM on the ETC assy.
During test execution, the test currently running, along with the description/name and status (pass/fail), are identifiedin ETC LEDs.
If at any point during the Power–ON Tests an error is encountered, the testing is halted and the error code displayson the ETC LEDs.
3-1-2 Reading ETC Board LEDs
The lower byte (8 bits) indicates the ETC process, the ETC Power–ON Test and current status in start–up sequence,and the upper byte (8 bits) indicates the ETC status.

3-3 ETHERNET ADDRESS VERIFICATION
This test is performed to check if the Ethernet address data back–uped by the internal battery to the ETC board isstored without error. If data is destroyed, first check if the internal battery has been consumed. Weak battery can notback up the Ethernet data into the RAM. (Normally for 5 to 10 years, the internal battery can be used without replace-ment.)
1. Connect the external terminal display to the CN4 of the ETC board.
2. Set the Dip switch (location:S6A) to the $4 position.

SECTION 3 – TGP OFF–LINE TEST
3-1 TABLE PROCESSOR OFF–LINE TEST
The TGP Assembly contains two micro processor system. (i.e., Gantry Processor and Table Processor)
Theses Processor systems can execute the OFF–LINE programs used for subsystem Adjustment, Functional Checkand Diagnostics.
Each Processor holds test programs in its own PROM. Execute each Processor’s OFF–LINE TEST program inde-pendently with the DIAG switches and test switches.
The Micro Processor displays the test results and/or error on the Gantry Display Panel, so it requires a normally oper-ating TABLE Processor display function. Execute the OFF–LINE TEST program after successful completion of theTABLE PROCESSOR DISPLAY TEST.
The OFF–LINE TEST program performs three operations:

2-1 ARTIFACT PROBLEM
The following illustrations are examples which may be caused by DAS component failure.
Single Channel Ring
The failure of one input capacitor or one Detector channel causes a singlefailure . Illustration shows an example of single channel ring. To identify aDAS channel, measure the ring diameter and use the ring diameter chart(Section 1-2).
Phantom
Single Channel Streak
If a single channel failure occurs during one view period, it appears assingle line on image (streak). To identify the DAS channel which caused thisstreak, use the circle cursor to measure the distance from image center tothe streak, then use the ring diameter chart (Section 1-2) to determine theDAS channel. This failure can also be caused by a single channel signalview data drop during data conversion or data transfer.
Phantom
22 Channel W ide Band
A unit conditioning circuit failure causes 22 channels to fail. Illustrationshows an example of a 22 Channel Wide Band Ring.Phantom

SECTION 1 – FAILURE ANALYSIS
1-1 LED INDICATORS
1-1-1 Power Cont Board
The Power Cont board contains 42 LEDs that provide XG system status and information. During XG system trouble-shooting, some LEDs provide valuable information that speeds up the troubleshooting process.
The LEDs D1 ∼ D5 illuminates only during OFF–LINE exposure mode, that is, when the cable is connected betweenCN15 and CN1. These LEDs display the XG system status during OFF–LINE exposure.
