96 Agilent X-Series Signal Generators SCPI Command Reference
System Commands
Calibration Subsystem (:CALibration)
Calibration Subsystem (:CALibration)
:ALC:MODulator:BIAS
Supported All Models
:CALibration:ALC:MODulator:BIAS
This command performs the ALC modulator bias calibration. The adjustment compensates for ALC
open loop power drift due to temperature and humidity.
Key Entry Execute ALC Modulator Bias Adjustment
Remarks Use this calibration when the instrument is being used in the ALC open loop
mode.
:BBG:SKEW RFOut|EXTernal
Supported N5172B, N5182B
:CALibration:BBG:SKEW EXTernal, <value in pS>
:CALibration:BBG:SKEW? EXTernal
This command enters a calibration value that will correct the inherent External Output I/Q skew due
to differences in the I/Q physical paths.
EXTernal[1]|2:DC
Supported All Models
:CALibration:EXTernal[1]|2:DC
This command initiates a DC offset calibration for the external source specified.
NOTE If the calibration is performed with a dc signal applied, any deviation provided by the dc
signal will be removed and the new zero reference point will be at the applied dc level.
Key Entry External DC Cal
Remarks Use this calibration for externally applied DC signals.
:IQ:DC
Supported N5172B with Option 653 or 655, N5182B with Option 656 or 657
:CALibration:IQ:DC
This command performs a one to two second adjustment that is not traceable to a standard. However,
it will minimize errors associated with IQ gain, quadrature, and offset voltages. This adjustment
minimizes errors for the current signal generator setting and at a single frequency. The DC
adjustment is volatile and must be repeated with each signal generator setting change. This command
can be sent while the RF On/Off is set to Off and the adjustment will still be valid when the RF is
enabled. IQ must be on to perform this adjustment.
