Operating Manual 1145.1084.12 – 30 1033
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:RF:NFIGure[:ACQuire]
Starts the RF source calibration (1
st
power calibration step for mixer noise figure measurements), stores
and applies the calibration data.
The effect of this command is identical to the mixer command
SOURce<Ch>:POWer<Pt>:CORRection:MIXer:RF[:ACQuire].
Example:
FREQ:CONV MIX
...
Select mixer measurement mode in order to prepare a mixer noise figure 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:NFIGure
Start the RF source calibration. Change the test setup for the IF receiver calibration (see
mixer calibration procedure).
CORR:POWer:MIX:IF:NFIGure:ACQuire
Start the IF receiver calibration.
Proceed with the noise figure measurement settings, noise figure calibration etc.; see
also Noise Figure Measurement (Programming).
SOURce<Ch>:POWer<Pt>:CORRection:NREadings <readings>
Sets a limit for the number of calibration sweeps in the source power calibration. The command is valid for
all channels, ports and external generators. Equivalent command:
SOURce<Ch>:POWer<Pt>:CORRection:COLLect:AVERage[:COUNt].
<Ch>
Calibrated channel number. This parameter is ignored; the limit applies to all
sources.
<Pt>
Calibrated port number. This parameter is ignored; the limit applies to all
sources.
