The self-tests are used for isolating problems in the oscilloscope. To avoid any erroneous
results, a key-down powerup sets critical parameters to known values. To start the tests:
Perform a key-down powerup.
Press Utility ,thenpress selftest menu.
The following figure shows the choices in the self-test menu. The tests may be run
individually or, by selecting test all, consecutively. The message PASSED or FAILED is
displayed after the completion of each test. If there are failure messages for acquisition
circuitry, it may help to perform the calibration procedures in chapter 4, "Calibrating and
Adjusting." If self-tests continue to fail, the main assembly requires service by HP. This guide
does not support component-level troubleshooting.
The loop test in the self-test menu is used for HP service only.
