Example:
*RST; CORR:POW:ACQ AWAVe,1,PORT,1
Perform a receiver power calibration of the wave a
1
using port 1
as a source port, assuming that the transmitted source power a
1
is correct. No external cabling is needed.
CORR:POW:AWAV?
Check whether the calibration is applied (the response is 1).
CALC:PAR:MEAS 'TRC1', 'A1'
Select a
1
as a measured quantity for the default trace.
CALC:MARK ON; MARK:Y?; :SOUR:POW?
Create marker no. <Mk> in the center of the sweep range and
query the measurement value. The calibrated power of the refer-
ence wave a
1
is approx. equal to the default source power value.
See also example for [SENSe<Ch>:]CORRection:
OFFSet<PhyPt>[:STATe].
Usage:
Setting only
Manual operation: See "Port Overview" on page 478
[SENSe<Ch>:]CORRection:POWer<PhyPt>:AWAVe[:STATe] <Boolean>
Enables or disables the receiver power calibration for channel <Ch> and for the refer-
ence waves a
n
. The setting command is disabled unless the reference waves have
been power calibrated ([SENSe<Ch>:]CORRection:POWer<PhyPt>:ACQuire
on page 1261 AWAVe,...). The query always returns a result.
This command extends the functionality of manual control, where the reference
receiver calibration is included in the source power calibration of each port (and always
ON).
Suffix:
<Ch>
.
Calibrated channel number
<PhyPt> Calibrated port number
Parameters:
<Boolean> Enables (ON) or disables (OFF) the receiver power calibration
for the reference waves a
n
.
*RST: OFF

[SENSe<Ch>:]CORRection:POWer:DATA <Wave>, <CorrData>...
[SENSe<Ch>:]CORRection:POWer:DATA:PORT<PhyPt> <Wave>, <CorrData>...
Reads or writes receiver power correction data sets. A power correction data set con-
tains n real values where:
●
Each value corresponds to the ratio of the actual power at the receiver input (value
provided by the used source) to the uncalibrated power in dB.
●
The number n is equal to the number of sweep points.
