power of +35 dBm.
SOURce<Ch>:POWer<Pt>:CORRection:MIXer:IF[:ACQuire]
Starts the IF source calibration, stores and applies the calibration data. The IF source calibration is the 2
nd
power calibration step for vector mixer measurements; it may be used as well for scalar mixer
measurements with enhanced wave correction.
The external power meter is selected via SOURce<Ch>:POWer<Pt>:CORRection:PMETer:ID.
The IF source calibration is independent of the RF source and LO source calibration; see description
of the mixer calibration procedure.
<Ch>
Calibrated channel number
<Pt>
Calibrated port number. This suffix is ignored; the port is selected via
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:IFPort. In a mixer delay or
vector mixer measurement the IF signal is always measured at port 2.

Example:
FREQ:CONV VMIX
...
Select a vector mixer measurement; set frequencies, see e.g. example for
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:TFRequency.
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.
SOUR:POW:CORR:MIX:RF
Start the RF source calibration. Change the test setup for the IF source calibration
(see mixer calibration procedure).
SOUR:POW:CORR:MIX:IF
Start the IF source calibration.
FREQ:CONV:MIX:LOIN 3
Select port no. 3 as a signal source for the LO signal. Adjust the test setup for the LO
source calibration.
SOUR:POW:CORR:MIX:LO
Start the LO source calibration.
SOURce<Ch>:POWer<Pt>:CORRection:MIXer:LO<Stg>[:ACQuire]
Starts the LO source calibration (3
rd
power calibration step for scalar and vector mixer measurements, 4
th
calibration step for two-stage scalar mixer measurements), stores and applies the calibration data. The
external power meter is selected via SOURce<Ch>:POWer<Pt>:CORRection:PMETer:ID.
