CALCulate:SCALe:DB:REFerence {<reference>|MIN|MAX|DEF}
CALCulate:SCALe:DB:REFerence? [{MIN|MAX|DEF}]

Stores a relative value in the multimeter's dB Relative Register, which is used for the dB function in CALCulate:SCALe:FUNCtion. When the dB function is enabled, this value is subtracted from each voltage measurement after the measurement is converted to dBm.

Parameter Typical Return
-200.0 dBm to +200.0 dBm. Default: 0. +3.00000000E+02

Enable dB scaling with a -10 dB reference and a 300 Ω dBm reference resistance:

CALC:SCAL:DBM:REF 300
CALC:SCAL:DB:REF -10.0
CALC:SCAL:FUNC DB
CALC:SCAL:STAT ON

CALCulate:SCALe:DBM:REFerence {<reference>|MIN|MAX|DEF}
CALCulate:SCALe:DBM:REFerence? [{MIN|MAX|DEF}]

Selects the reference resistance for converting voltage measurements to dBm. This reference value affects the dBm and dB scaling functions.

Parameter Typical Return
50, 75, 93, 110, 124, 125, 135, 150, 250, 300, 500, 600, 800, 900, 1000, 1200 or 8000 Ω. Default: 600. +3.00000000E+02

Enable dBm scaling with a reference resistance of 300 Ω:

CALC:SCAL:DBM:REF 300
CALC:SCAL:FUNC DBM
CALC:SCAL:STAT ON

CALCulate:SCALe:FUNCtion {DB|DBM|PCT|SCALe}
CALCulate:SCALe:FUNCtion?

Selects the operation performed by the scaling function.

Parameter Typical Return
{DB|DBM|PCT|SCALe} DB, DBM, PCT, or SCALe

Enable the DB scaling function referenced to the next measurement taken:

CALC:SCAL:FUNC DB
CALC:SCAL:STAT ON

CALCulate:SCALe:GAIN {<gain>|MIN|MAX|DEF}
CALCulate:SCALe:GAIN? [{MIN|MAX|DEF}]
