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.

Parameter Typical Return

50、75、93、110、124、125、135、

150、250、300、500、600((default)、

800、900、1000、1200 or 8000Ω

+6.00000000E+02

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.
