:CALibration Subsystem

The calibration subsystem is used to set the controls and the parameters associated with

instrument calibration.

DCFM/DCΦM Calibration

:CALibration:DCFM

There is no query for this command.

This command initiates a DCFM or DC

ΦM calibration (depending on which kind of

modulation is currently active) and stores the results in the instrument’s firmware. This

calibration eliminates the offset in phase (or frequency, as appropriate) modulation so that

the carrier phase (or frequency) remains the same with no modulation applied. An external

DC-coupled phase (or frequency) modulation must be active when the calibration is

performed. After calibration, the DC signal produces no modulation.

There are no initial values associated with this command.

Default I/Q Calibration

:CALibration:IQ:DEFault

The is no query for this command.

This command will restore the original factory calibration data for the internal I/Q

modulator. The latest calibration data from the user calibration is discarded. Although the

factory calibration data may not be optimized for the signal generator’s present status, the

data can be used as a starting point if the current data is lost (if the I/Q calibration is

unable to execute).

There are no initial values associated with this command.

Full I/Q Calibration

:CALibration:IQ:FULL

There is no query for this command.

This command sets and performs a full-frequency range (regardless of the start and stop

frequency settings) I/Q calibration and stores the results in the instrument’s firmware.

There are no initial values associated with this command.
