Fig. 5-12: Selftest dialog
In the dialog you can select one or several tests. Each selftest may be performed once
or continuously. Moreover you can save any configuration of the "Selftest" dialog to a
"profile" for later reuse.
The result of each test ("State") is displayed in the individual test section:
●
Invalid: No test performed yet, no result available
●
In progress: Test running, no result available yet
●
Passed: Test passed, all measurements within the factory-set tolerances
●
Failed: Test failed, one or more measurements out of tolerances
●
Skipped: Test skipped because it could not be performed with the current instrument
configuration (this happens e.g. if you try to initiate an OXCO test while "Frequency
Source: External" is active).
TCXO / OCXO selftest
To perform a selftest on the Temperature Controlled Crystal Oscillator (TCXO) or on the
optional oven quartz (Timebase OCXO, option R&S CMW-B690A), you have to switch
the R&S CMW500 to internal reference frequency source; see Sync Settings. Internal
reference frequency ensures that the oscilllators are power-supplied.
