To Check The Power-Up Tests - HP 1660C Series Service Manual

To check the power-up tests

The logic analyzer automatically performs power-up 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"
prints on the screen in front of the name of each test.
Disconnect all inputs, then insert a formatted disk into the flexible disk drive.
1
Let the instrument warm up for a few minutes, then cycle power by turning off then
2
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.
As the tests complete, check if they pass or fail.
