.~~~~~~~~.~~~. This fun&ion examines, in order, the pass/fail status of ail
internal tests and displays NO FAILURE FOUND if no tests have failed.
If a failure is detected, the routine displays the assembly or assemblies most
probably faulty and assigns a failme probability factor to each assembly.
Test Descriptions
The analyzer has up to 80 routines that test, verify, and adjust the instrument.
This section describes those tests.
Internal Tests
This group of tests runs without external connections or operator interaction.
All return a PASS or FAIL condition. All of these tests run on power-up and
PRESET except as noted.
0
ALL INT. Runs only when selected. It consists of internal tests 3-11,
13-16, and 20. Use the front panel knob to scroll through the tests and
see which failed. If aIl pass, the test displays a PASS status. Each test
in the subset retains its own test status.
1 PRESET. Runs the following subset of internal tests: first, the
ROM/RAM tests 2, 3, and 4; then tests 5 through 11, 14, 15, and 16. If
any of these tests fail, this test returns a FAIL status. Use the front
panel knob to scroll through the tests and see which failed. If all pass,
this test displays a PASS status. Each test in the subset retains its own
test status. This same subset is available over HP-IB as “TST?“. It is not
performed upon remote preset.
2
ROM. Part of the ROMJRAM tests and cannot be nm separately. Refer
to the “Digital Control Troubleshooting” chapter for more information.
