For ESA backwards compatibility, the legacy SCPI command
CALibration:SOURce:STATe <boolean> (ESA's Amptd Ref Out SCPI) will
still be supported and mapped as follows:
When CALibration:SOURce:STATe ON is received [SENSe]:FEED:AREF
REF50 will execute
When CALibration:SOURce:STATe OFF is received [SENSe]:FEED:AREF
OFF will execute
When CALibration:SOURce:STATe? is received, 1 will be returned if any of
the references is selected and 0 if the Calibrator is "Off"

The 4.8 GHz internal reference is only available in some models and
frequency range options. If the 4.8 GHz reference is not present, the
softkey will be blanked, and if the REF4800 parameter is sent, the analyzer
will generate an error.
