The following procedure checks the basic operation of the merged modules.
NOTE
. Running the extended diagnostics will invalidate any acquired data. If
you want to save any of the acquired data, do so before running the extended
diagnostics.
Prerequisites Warm-up time: 30 minutes
Merge cable installed between all of the LA merged modules
Power-up diagnostics pass
SELF_CAL passes
Perform the following steps to complete the functional verification procedures.
Before beginning this procedure, be sure that no active signals are applied to the
instrument. Certain diagnostic tests will fail if signals are applied to the probe
during the test.
1. In the logic analyzer application, go to the System menu and select
Calibration and Diagnostics.
2. Click the Extended Diagnostics tab.
3. Select the top level test and click the Run button.
The diagnostics will perform each one of the tests listed in the menu under
the module selection. All tests that displayed an Unknown status will change
to a Pass or Fail status depending on the outcome of the tests.
4. Scroll through the test results and verify all tests pass.
NOTE
. If Extended Diagnostics fail, run Self Cal for the LA modules and then
rerun Extended Diagnostics.
