The LO source calibration is independent of the RF source and IF receiver calibration; see description
of the mixer calibration procedure.
<Ch>
Calibrated channel number
<Stg>
Mixer stage (signals LO 1 or LO 2; see
SENSe<Ch>:]FREQuency:CONVersion:MIXer:STAGes)
<Pt>
Calibrated port number. This suffix is ignored; the port is selected via
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOPort<Stg>.
SCPI,
Command
Types
Device-specific, no query
Example:
See SOURce<Ch>:POWer<Pt>:CORRection:MIXer:RF[:ACQuire].
SOURce<Ch>:POWer<Pt>:CORRection:MIXer:RF[:ACQuire]
Starts the RF source calibration (1
st
power calibration step for scalar and vector mixer measurements),
stores and applies the calibration data. The external power meter used is selected via
SOURce<Ch>:POWer<Pt>:CORRection:PMETer:ID.
For scalar mixer measurements the command initiates two calibration sweeps, the first over the RF
frequency range, the second over the IF frequency range (for a subsequent receiver power calibration,
[SENSe<Ch>:]CORRection:POWer<port_no>:MIXer:IF:ACQuire). See description of the mixer
calibration procedure. If the RF image correction is enabled in addition
([SENSe<Ch>:]FREQuency:CONVersion:MIXer:PRFimage ON), a third calibration sweep in the RF
image frequency range is added.
<Ch>
Calibrated channel number
<pt>
Calibrated port number. This suffix is ignored; the port is selected via
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:RFPort. In a mixer delay or
vector mixer measurement the RF signal is always generated at port 2.

Example:
FREQ:CONV MIX
...
Select a scalar 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 receiver calibration
(see mixer calibration procedure).
CORR:POWer:MIX:IF:ACQuire
Start the IF receiver calibration.
