Error Queues
If an error condition occurs in the instrument, it may be reported to
both the history error queue (front panel display) and the SCPI error
queue (remote interface). These two queues are viewed and managed
separately. Some programming errors are not applicable to front panel
operation, so they are only reported through the SCPI remote interface
error queue.
Error messages will appear as they occur in the Status/Info bar that
appears at the bottom of the display. To view error messages fully you
will use keys in the
System, Show Errors menu.
NOTE If there are any messages in the history error queue, the Err
annunciator will be activated on the instrument display.

Annunciators
The display annunciators show the status of some of the transmitter
tester functions and indicate error conditions of the instrument. Error
annunciators are shown in red text on the instrument display. Where
applicable, some states will appear in green, indicating that the feature
is active and performing correctly. The state will change to red if the
feature fails. The following annunciators are available:
Unlock - This annunciator indicates that one or more of the internal
phase-locked loops are unable to maintain a phase-locked state.
Corr Off (corrections off) - This annunciator appears when the
Corrections softkey is set to off.
Err (error) - This annunciator appears when an error message is
placed in the history error queue. It will persist until you use the
Clear Error Queue(s) key to clear the history error queue.
