[:SOURce]:ROSCillator:EXTernal:RFOFf[:STATe] <State>
Activates that RF output is automatically switched off, when in external source mode
no reference signal is supplied.
This setting ensures that no improper RF signal due to the missing external reference
signal is output and used for measurements.
In addition to the error message "Ext Ref missing", the instrument generates the mes-
sage "RF output deactivated'.
Parameters:
