SOURce:POWer:CORRection:DEFault <Boolean>
Enables the analyzer to create a set of default source power calibration data. The ana-
lyzer uses the reference channel power to acquire the default calibration data. No
external power meter is required.
Tip:
The main purpose of the default calibration data set is to provide a dummy power cali-
bration which you can replace with your own, external power calibration data. You may
have acquired the external data in a previous session or even on an other instrument.
If you want to use the external power calibration data on the analyzer, generate the
default data set first and overwrite it with the external data. For details refer to the pro-
gram example below.
Parameters:
<Boolean> Enables (ON|1) or disables (OFF|0) the dummy source power
calibration for port number <PhyPt>. OFF means that a real
source power calibration is performed, for which an external
power meter must be connected to the analyzer.
*RST: OFF|0
Example:
*RST; :SWE:POIN 10
Reset the instrument and reduce the number of sweep points to
10.
SOUR:POW:CORR:COLL:DEF ON
Enable a dummy source power calibration.
SOUR:POW:CORR:ACQ PORT,1
Perform a dummy source power calibration using port 1 as a
source port.
SOUR:POW:CORR:DATA? 'A1'
Query the correction values. The analyzer returns 10 comma-
separated real numbers.
MMEM:STOR:CORR 1,'Calgroup_Ch1.cal'
Store the default source power calibration data to the calibration
pool in the default directory C:\Rohde&Schwarz\NWA\Calibra-
tion\Data.
<Replace the generated file Calgroup_Ch1.cal with your exter-
nal power calibration data.>
MMEM:LOAD:CORR 1,'Calgroup_Ch1.cal'
Load the external data and apply them to channel 1 and port 1.
DISP:MENU:KEY:EXEC 'Cal Manager'
Open the Calibration Manager dialog to check the result of the
previous actions.
SOURce:POWer:CORRection:FAST <Boolean>
Enables or disables a fast source power calibration, where the external power meter is
used for the first calibration sweep only.
It is recommended to use the more general command SOURce:POWer:CORRection:
COLLect:METHod.
