Example:
SOUR:POW:CORR:OSO:STAT OFF
To improve the accuracy, switch off all other sources during the
calibration sweep.
SOUR:POW:CORR:NRE 2; COLL:AVER:NTOL 0.5
Increase the number of readings and reduce the power toler-
ance to improve the accuracy.
SOURce:POW:CORR:COLL:CFAC 0.9
Reduce the correction factor to 0.9.
SOURce:POW:CORR:PSELect PPOW; PPOWer -5
Define reference receiver cal power which is independent of the
port power; set its value to -5 dBm.
SOUR:POW:CORR:ACQ PORT,1
Perform a source power calibration using port 1 as a source
port.
SOUR:POW:CORR:STAT?
Check whether the calibration is applied (the response is 1).
Example:
Change the test setup, connect a previously configured external
generator no. 1 to the reference plane.
SOUR:POW:CORR:ACQ GEN,1
Perform a source power calibration using the external generator
no. 1 as a source.
SOUR:POW:CORR:GEN?
Check whether the calibration is applied (the response is 1).
Usage: Setting only
Manual operation: See "Port Overview" on page 444
SOURce<Ch>:POWer<PhyPt>:CORRection[:ACQuire]:VERification:RESult?
Returns (and deletes) the result of the last verification sweep. The response contains
three values:
●
<Channel> – calibrated channel, e.g. Ch 1 for channel no. 1.
●
<Boolean> – 1 for "calibration passed" (the maximumr offset is below the toler-
ance), 0 for "calibration failed".
●
<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.
