SOURce<Ch>:POWer<Pt>:CORRection[:ACQuire] PORT | GENerator | CONVerter |
A1 | A2 | A3 | A4 | ESRC1 | ESRC2, <source_pt>
Selects the port for the source power calibration, starts and applies it.
The source power calibration(s) to be performed can be selected using
SOURce:POWer:CORRection:COLLect:FLATness ON|OFF (flatness calibration) and
SOURce:POWer:CORRection:COLLect:RRECeicver ON|OFF (reference receiver calibration).
In converter mode a flatness calibration can only be performed for converters with electronic attenuator
(R&S ZVA-ZxxxE) and with SOURce<Ch>:POWer<Pt>:CONVerter:TRANsfer:DESCription set to
ELECtronic. A reference receiver calibration, on the other hand, can always be performed.
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.
<Ch>
Calibrated channel number
<pt>
Calibrated port number. This suffix is ignored because the port number is
specified in the parameter list.
PORT
GENerator
CONVerter
Analyzer port is the source of the calibrated wave.
External generator is the source.
Frequency converter is the source.
The port, generator, or converter numbers are specified by means of the
<source_number> parameter.
A1 | A2 | A3 | A4
Direct analyzer port selection. The parameters A1 and A2 are ZVR-compatible.
No additional <port_number> parameter needs to be specified.
ESRC1 | ESRC2
Direct external generator selection. The parameters are ZVR-compatible. No
additional parameters need to be specified.
<source_pt>
Analyzer port / generator port / converter port number, if PORT / GENerator /
CONVerter is the first parameter.
Range [def. unit]
1 to port number of the analyzer/number of external generators [–]

Example 1:
*RST; SOUR:POW:CORR:COLL:VER 0
Disable the verification sweep to speed up the source power calibration
procedure.
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; COLL: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.
