Remote Operation 5-17
CALibration[:INTernal]:AUTOcal
Description: Performs a multi-point sensor gain calibration of the selected sensor with the internal 50 MHz
calibrator. This procedure calibrates the sensor’s linearity at a number of points across its entire
dynamic range. The calibration source defaults to the instrument’s internal calibrator if not
specified.
Syntax: CALibration[1|2][:INTernal]:AUTOcal[?]
Returns: 0 if successful, 1 otherwise (using query form only)
Valid Modes: Peak and CW Power sensors only
CALibration[:INTernal]:FIXedcal
Description: Performs a calibration at a fixed frequency and level. Fixed-cal does not provide for automatic
control of the internal 50 MHz calibrator. The RF output level of the calibrator in use must be set
by the user. Fixed-cal assumes that a valid Zero has already been performed.
Syntax: CALibration[1|2][:INTernal]:FIXedcal[?]
Returns: 0 if successful, 1 otherwise (using query form only)
Valid Modes: CW Power sensors only
CALibration[:INTernal]:ZERO
Description: For a sensor that has been previously auto calibrated and has valid auto-cal status, performs a zero
offset null adjustment. The sensor does not need to be connected to any calibrator for zeroing –
the procedure is often performed in-system. However, this command will turn off the internal
calibrator prior to zeroing to avoid the need to perform this step explicitly.
Syntax: CALibration[1|2][:INTernal]:ZERO[?]
Returns: 0 if successful, 1 otherwise (using query form only)
Valid Modes: Any
