If a test or adjustment 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 instrument display such as unlock or overload states that signal an instrument failure.
If the test or adjustment can be completed as normal but 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.
