HP 16500C Service Manual

To check the power-up self-tests
The logic analysis system automatically performs power-up self-tests when you apply power
to the instrument. The revision number of the operating system shows in the upper-right
corner of the screen during these power-up tests. As each test completes, either "passed" or
"failed" appears on the screen in front of the name of each test.
1
Disconnect all inputs, then insert a formatted disk into the flexible disk drive.
2 Let the instrument warm up for a few minutes, then cycle the power by turning off
and turning on the power switch.
If the instrument is not warmed up, the power-up test screen will complete before you can
view the screen.
3
As the tests complete, check if they pass or fail, then return to the flowcharts.
The Flexible Disk Test reports No Disk if a disk is not in the disk drive. Refer to the tables
below for the screen listing after the tests are complete and for power-up error messages.
