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 289
[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 1019
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
Example: See
[SENSe<Ch>:]CORRection:POWer<PhyPt>:ACQuire
[SENSe<Ch>:]CORRection:POWer<PhyPt>:IMODulation:ACQuire
Starts the receiver calibration (3 rd power calibration step for intermodulation measure-
ments), stores and applies the calibration data.
