TM 11-6625-3145-14
Maintenance: Troubleshooting-318/338 Service
During this test, all outputs of the ACQ Memories on the A04 board are disabled (maintained low) y forcing BS high from
U114 (hex D master-slave flip-flop, 10176) on the A04 board. U1 14 is written by the MPU at I/O address 5A
hex
.
The MPU reads the data from the A04 board at I/O address 59
hex
, i.e., with READ ACQ DATA from 112 (binary to 1-8
decoder/multiplexer, 10162) on the A03 board. This reading sequence is the ame as in the ACQ Test.
Then the MPU compares the MSB of the data read to the one expected. If they don’t match each other, an error message
will be issued.

SEQ TEST
Program: SEQ
Function:
Power on - A single acquisition with a full trigger sequence is simulated to check a whole operation.
Troubleshooting - The content of this test is the same as that run automatically when the power s first turned on, but here
the Looping feature is available. The Looping feature has 4 options; OFF, /O, ERROR, and TEST. When the LOOP field
is set to I/O, the looping feature allows only I/O instructions to be run repeatedly. The I/O address will appear on the
screen. When the field is set to ERROR, the looping feature allows the tests in which an error is detected to be run
repeatedly. When the field is set to TEST, the looping feature allows one test, or sequence of tests, to be run
continuously. When the field is set to OFF, the looping feature is not available and one test, or sequence of tests, will run
once.
When I/O Looping is selected, only those selected OUT instructions (subroutines), including one of the addresses listed
below, will run. Unless the STOP key is pressed, this test will continue looping without displaying the result of the
verification. In this case, the user should use an oscilloscope to observe the Acquisition circuit board.

write WA into High-speed memory.
When ERROR is selected, looping will occur only if errors are detected. If no errors are detected, the ERROR looping test
will run through its tests only once, and the results of the verification will be displayed on the CRT just as if the looping field
had been selected to OFF. If errors are detected, the ERROR Looping function is available for the read cycle of the test,
and the result of the verification will appear on the screen. Refer to the
in this manual for an explanation of
error codes.
Description: A single acquisition is simulated to check the trigger sequencer operation. Pseudo data is generated in
exactly the same way used in the WR and ACQ tests, and applied to the latches on the A01 INPUT-A and INPUT-B
boards.
