I/Q Cable Calibrate...
Invokes the guided cable calibration. The guided cable calibration steps the user through a calibration of
all ports (I, I-bar, Q, and Q-bar) using just a cable (no probe attached). See

RF Calibrator

Lets you choose a calibrator signal to look at or turns the calibrator "off" (switches back to the selected
input). When one of the calibrator signals is selected, the analyzer routes that signal (an internal
amplitude reference) to the analyzer, while leaving the main input selection (RF or I/Q) unchanged.
This function presets to OFF on a Mode Preset, which causes the internal circuitry to switch back to the
selected input (RF or I/Q).

Input/Output
[:SENSe]:FEED:AREFerence REF50|REF4800|OFF
[:SENSe]:FEED:AREFerence?
FEED:AREF REF50 selects the 50 MHz amplitude reference as the signal
input.
FEED:AREF REF4800 selects the 4.8 GHz amplitude reference as the signal
input
FEED:AREF OFF turns the calibrator "off" (switches back to the selected
input – RF or I/Q)
Selecting an input (RF or I/Q) turns the Calibrator OFF. This is true whether
the input is selected by the keys or with the [:SENSe]:FEED command.
The 4.8 GHz internal reference is only available in some models and
frequency range options. If the 4.8 GHz reference is not present, the
softkey will be blanked, and if the REF4800 parameter is sent, the analyzer
will generate an error.
