Remote Operation

CALibration:{INTernal|EXTernal}:FIXedcal

Description:

Performs a single point sensor gain calibration of the selected sensor with selected calibra-
tor. This procedure calibrates the sensor’s gain at a single point. At other levels, that gain
setting is combined with stored linearity factors to compute the actual power.

Syntax:

CALibration[1|2]:{INTernal|EXTernal}:FIXedcal[?]

Returns:

0 if successful, 1 otherwise (query form only)

Valid Modes:

CW sensors only. For peak sensors, use AUTOcal.

CALibration:{INTernal|EXTernal}:AUTOcal

Description:

Performs a multi-point sensor gain calibration of the selected sensor with selected calibra-
tor. This procedure calibrates the sensor’s linearity at a number of points across its entire
dynamic range, and is the recommended method when maximum accuracy is required.

Syntax:

CALibration[1|2]:{INTernal|EXTernal}:AUTOcal[?]

Returns:

0 if successful, 1 otherwise (query form only)

Valid Modes:

Power sensors only.

CALibration:USER:FREQcal

Description:

Performs a single-point sensor gain calibration of the selected sensor using an external
(user-supplied) 0dBm power reference at the current operating frequency. This method can
be combined with an AUTOCAL to yield the most accurate power readings at frequencies
that are far from the calibration frequency. It temporarily replaces the calfactor computed
from the sensor’s factory-stored values with a measured value.

Syntax:

CALibration[1|2]:USER:FREQcal[?]

Returns:

0 if successful, 1 otherwise (query form only)

Valid Modes:

Power sensors only.

4.5.16 MEMory Subsystem

The MEMory group of commands is used to save and recall instrument operating configurations, and to edit and
review user-supplied frequency dependent offset (FDOF) tables for external devices in the signal path. Up to four
configurations may be saved, and two frequency dependent offset tables. Note, however that assigning a stored
FDOF table to a particular measurement channel is not a MEMory command; it is handled through the SENSe sub-
system.

MEMory:SYS:LOAD

Description:

Recall a stored instrument setup from location 1 thru 4.

Syntax:

MEMory:SYS{1|2|3|4}:LOAD

Argument:

None

Valid Modes:

Any
