CALCulate:SCALe:REFerence:AUTO {ON|1|OFF|0}
CALCulate:SCALe:REFerence:AUTO?
Enables or disables automatic reference selection for the dB scaling functions.
Parameter
{ON|1|OFF|0}. Default: ON.
Enable the DB function with automatic reference selection and use the first measurement as the reference
value:
CALC:SCAL:DBM:REF 50
CALC:SCAL:FUNC DB
CALC:SCAL:REF:AUTO ON
CALC:SCAL:STAT ON
READ?
ON: the first measurement made is used as the reference for all subsequent measurements, and auto-

matic reference selection is disabled:
For the dB scaling function, the first measurement is converted to dBm, and

This parameter is set to its default value after a Factory Reset (*RST), an Instrument Preset

You must execute CALCulate:SCALe:FUNCtion before executing CALCulate:SCALe[:STATe], otherwise

an incompatibility error will be generated.
Scaling is set to OFF when you change measurement functions (for example, changing from DCV to

ACV). You must re-enable scaling after changing measurement functions.
