2.4.2 CALCulate:SCALe:DBM:REFerence {<reference>|MIN|MAX|DEF}
CALCulate:SCALe:DBM:REFerence? [{MIN|MAX}]
Selects the reference resistance for converting voltage measurements to dBm. This
reference value affects the dBm and dB scaling functions.
Note:This command applies only to ACV and DCV measurement functions.

Enable dBm scaling with a reference resistance of 600 Ω:
CALC:SCAL:DBM:REF 600
CALC:SCAL:FUNC DBM
CALC:SCAL:STAT ON
 The instrument sets the reference value to its default value after a Factory Reset
(*RST), an Instrument Preset (SYSTem:PRESet), a change in math function, or a
change in measurement function.
