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 reference wave a
1
is approx. equal to the default source power value.
See also example for
SENSe<Ch>:]CORRection:POWer<port_no>[:STATe].
[SENSe<Ch>:]CORRection:POWer<port_no>:AWAVe[:STATe] <Boolean>
Enables or disables the receiver power calibration for channel <Ch> and for the reference waves a
n
.
The command is disabled unless the reference waves have been power calibrated
(
[SENSe<Ch>:]CORRection:POWer<port_no>:ACQuire AWAVe,...
).
<Ch> Calibrated channel number
<port_no> Calibrated port number
<Boolean> Enables (ON) or disables (OFF) the receiver power calibration for
the reference waves a
n
.
*RST value OFF [–]

Types Device-specific, command or query
Example:
See [SENSe<Ch>:]CORRection:POWer<port_no>:ACQuire
[SENSe<Ch>:]CORRection:POWer<port_no>:DATA '<wave_string>', <block> |
<numeric_value>...
Reads or writes receiver power correction data sets. A power correction data set contains n real values
where:
ƒ
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.
ƒ
The number n is equal to the number of sweep points.
Increasing (decreasing) the values in the correction data sets increases (decreases) the input power
reading. Writing correction data (the setting command) fails if the number of transferred values is not
equal to the number of sweep points.
<Ch>
Calibrated channel number
<port_no> Calibrated port number
