Example:
SOUR:POW:CORR:OSO:STAT OFF
To improve the accuracy, switch off all other sources during the
calibration sweep.
SOUR:POWer:CORR:COLL:METH RRAF
Enable fast power correction.
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
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.
