<SourcePort> Analyzer port or generator port number, if PORT or GENerator is
the first parameter.
<CalOnlyPortFreq> Relevant for frequency conversion measurements only.
OFF | 0
The reference receiver at port <CalPort> is calibrated for all fre-
quencies that are relevant for any of the ports.
ON | 1
Only those frequencies are calibrated that are relevant for this
port. This results in shorter calibration times.
*RST: 0
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 "Port Overview" on page 597
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".
