Select power meter no. 1 (previously configured in the External Power Meters dialog
and properly connected) for the RF source calibration.
SOUR:POW:CORR:HARM
Start source power calibration at the previously selected source port 1.
CORR:POW:HARM:ACQ
Start receiver power calibration at the previously selected receive port 2.
CALC:PAR:MEAS? "TRC1"
Query the measured quantity. The analyzer measures the wave quantity b2, the
response is 'B2D1SAM'.
SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:LTONe[:ACQuire]
[Deprecated command, replaced by
SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:SPORts[:ACQuire]]
Starts the source calibration for the lower tone port (1
st
legacy power calibration step for intermodulation
measurements), stores and applies the calibration data. The external power meter used is selected via
SOURce<Ch>:POWer<Pt>:CORRection:PMETer:ID.
This command will perform a calibration only at the lower tone frequency (legacy power calibration). If the
intermodulation measurement is combined with a mixer measurement the calibration will be performed
both at the RF and the IF range of the lower tone frequency. To perform a calibration at all selected
intermodulation orders as well, use the command
SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:SPORts[:ACQuire] which combines steps 1
and 2 of the legacy power calibration into one step.
During this calibration the upper tone port of the intermodulation measurement is switched off.
<Ch>
Channel number
<pt>
Port number This suffix is ignored; the analyzer calibrates the port that is selected as
source port for the lower tone of the intermodulation measurement
([SENSe<Ch>:]FREQuency:IMODulation:LTONe).

Types
Device-specific, no query
Example:
*RST; FREQ:IMOD:LTON PORT,1; UTON PORT, 3
Reset the instrument to create the default channel no. 1. Select port 1 as a source
port for the lower tone, port 3 as a source port for the upper tone.
FREQ:IMOD:REC 2
Select port 2 as a receiver port.
FREQ:STAR 1GHZ; STOP 2GHz
Define a suitable sweep range to ensure that the analyzer can measure all
intermodulation products.
SOUR:POW:CORR:PMET:ID 1
Select power meter no. 1 (previously configured in the External Power Meters dialog
and properly connected) for the RF source calibration.
