6-7. Self-Tests

The self-tests for the HP 16532A oscilloscope module will identify the improper operation of major func- tional areas in the module. They are not intended for component level diagnostics.

If there are multiple oscilloscope modules, the user must select the specific oscilloscope module to be tested at the main test system menu. Multiple HP 16532A modules that are connected as one unit are rec- ognized as a single unit in the test menu. The external trigger cables connected to the ECL IN and ECL OUT do not need to be removed in order to do the self-test for each board. All other cable connections must be removed.

All self-tests can be run without access to the interior of the instrument. If a self-test fails, refer to section 6-8, "Troubleshooting."

Self-Test Access Procedure:

1.Disconnect all oscilloscope inputs and turn on the power switch.

2.From the startup screen, shown in figure 6-2, touch the Configuration field. Then, touch Test in the pop-up menu.
