SENSe<Sensor>:CORRection:SPDevice:LIST?
Queries the list of the S-parameter data sets that have been downloaded to the power
sensor. The result of the query indicates the consecutive number and mnemonic of
each data set.
Usage:
Query only
SENSe<Sensor>:CORRection:SPDevice:SELect <num>
Selects a downloaded data set for S-parameter correction.
See also Chapter 8.7.4.3, "S-parameter correction", on page 80.
Parameters:
<num> Range: 1 to 1999
*RST: 1; can differ if a calibration set defines another
value.
SENSe<Sensor>:CORRection:SPDevice:STATe <state>
Enables or disables the S-parameter correction. If activated, uses the S-parameter
data set selected by SENSe<Sensor>:CORRection:SPDevice:SELect.
See also Chapter 8.7.4.3, "S-parameter correction", on page 80.
Parameters:
<state> *RST: OFF; can differ if a calibration set defines another
value.
Example:
CORR:SPD:SEL 1
Selects an S-parameter correction data set.
CORR:SPD:STAT ON
Enables the S-parameter correction.
8.7.4.4 S-gamma corrections
Using the complex reflection coefficient, you can determine the power P delivered by
the signal source with considerably greater accuracy.
The coefficient of the signal source Γ
