Troubleshooting Test Failures
If a test will not proceed, then suspect either the setup is incorrect,
or the test equipment or DUT is faulty. Specifically you should:
-
Compare your test connections with the test setup on
the computer screen.
-
Ensure the cables and adapters are correct and not damaged.
-
Check the output and input connectors on the test equipment
for damage.
-
Check for error messages on the PSA display such as
unlock or overload states that signal an instrument failure.
If the test can be completed as normal, but the test fails, you should:
-
Ensure the equipment connections are torqued to proper
specs.
-
Ensure that cables and adapters meet the specifications
listed in the software and the Getting Started Guide.
-
Check cables and adapters for damage.
-
Check the output and input connectors on the test equipment
for damage.
-
Ensure that there are no error messages on the DUT screen
that can signal a problem elsewhere in the instrument.
