CALCulate:SCALe Subsystem
This subsystem controls math scaling.
Command Summary
CALCulate:SCALe:DB:REFerence
CALCulate:SCALe:DBM:REFerence
CALCulate:SCALe:FUNCtion
CALCulate:SCALe:GAIN
CALCulate:SCALe:OFFSet
CALCulate:SCALe:REFerence
CALCulate:SCALe:REFerence:AUTO
CALCulate:SCALe[:STATe]
CALCulate:SCALe:UNIT
CALCulate:SCALe:UNIT:STATe
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 CALCu-
late:SCALe:FUNCtion. When the dB function is enabled, this value is subtracted from each voltage meas-
urement 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
l Specifying a reference value disables automatic reference selection (CALCu-
late:SCALe:REFerence:AUTO OFF).
l The dB relative value parameter is relative to the dBm reference resistance set with CALCu-
late:SCALe:DBM:REFerence.
l The instrument sets the reference value to 0.0 with automatic reference selection enabled after a Fact-
ory Reset (*RST), an Instrument Preset (SYSTem:PRESet), or a change in measurement function.
