●
<MaxOffset> – maximum power offset between the measured power at the refer-
ence plane and the "Cal Power" during the verification sweep in dB.
If no verfication sweep is available, or if the result has been queried already, the
response is 0.
Suffix:
<Ch>
.
Calibrated channel number. This suffix is ignored; the result is
based on the last verification sweep acquired.
<PhyPt> Calibrated port number. This suffix is ignored; the result is based
on the last verification sweep acquired.
Example:
*RST; :SOURce:POWer:CORRection:NREadings 2
SOURce:POWer:CORRection:COLLect:AVERage:
NTOLerance 0.5
Increase the number of readings and reduce the power toler-
ance to improve the accuracy.
SOURce:POWer:CORRection:ACQuire PORT,1
Perform a source power calibration using port 1 as a source
port.
SOURce:POWer:CORRection:ACQuire:VERification:
RESult?
Query the result of the verification sweep. Possible response:
Ch1 1,9.9E+002
Usage:
Query only
Manual operation: See "Calibration Sweep Diagram" on page 596
SOURce<Ch>:POWer:CORRection:DATA <Source>, <CorrData>...
SOURce<Ch>:POWer:CORRection:DATA:PORT<PhyPt> <Source>, <CorrData>...
Reads or writes scalar source power correction data sets. A power correction data set
contains n real values where:
●
Each value corresponds to the ratio of the actual power at the reference plane
(value provided by the used source) to the uncalibrated power in dB.
●
The number n is equal to the number of sweep points.
Increasing (decreasing) the values in the correction data sets increases (decreases)
the power at the reference plane. Writing correction data (the setting command) fails if
the number of transferred values is not equal to the number of sweep points.
Suffix:
<Ch>
.
Calibrated channel number
<PhyPt> Physical port number, used to select a specific frequency axis in
arbitrary mode (with option R&S ZNA-K4).
