Note:
The command cannot be used unless a power meter is connected via GPIB bus,
USB or LAN interface and configured in the "External Power Meters" dialog.
Suffix:
<Ch>
.
Calibrated channel number
<PhyPt>
Calibrated port number. This suffix is ignored because the port
number is specified in the parameter list.
Parameters:
<SourcePort>
Analyzer port number, if PORT is the first parameter.
Range:
1 to port number of the analyzer / number of external
generators.
Setting parameters:
<SourceType>
PORT | GENerator | A1 | A2 | A3 | A4 | ESRC1 | ESRC2
PORT
–
analyzer port is the source of the calibrated wave.
GENerator
–
not supported.
The port numbers are specified by means of the
<SourcePort>
parameter.
A1 | A2 | A3 | A4
–
direct analyzer port selection. The parameters
A1 and A2 are ZVR-compatible. No additional port number param-
eter needs to be specified.
ESRC1 | ESRC2
–
not supported.
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; PMR 2
Enable fast power correction with two power meter readings.
SOUR:POW:CORR:NRE 2; COLL:AVER:NTOL 0.5
Increase the number of readings and reduce the power tolerance
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
).
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.
