[SENSe<Ch>:]CORRection:COLLect:NFIGure[:ACQuire] RECeiver | SOURce |
ATTenuator
Starts a noise figure calibration sweep for the NWA receiver, NWA source, or an external attenuator. The
port assignment is defined via [SENSe<Ch>:]CORRection:COLLect:NFIGure:STARt.
If the mixer mode is active (mixer noise figure measurement, with option R&S ZVA-K31), then the
command starts two calibration sweeps for each calibration step, one in the RF frequency range, the other
in the IF frequency range. 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.
A noise figure calibration must be terminated with one of the following commands, to be sent
immediately after the sequence of ...[:ACQuire] commands:
[SENSe<Ch>:]CORRection:COLLect:NFIGure:END – terminate calibration, discarding the acquired
calibration data (the active channel is not calibrated)
[SENSe<Ch>:]CORRection:COLLect:NFIGure:SAVE – terminate calibration, applying the acquired
calibration data (the active channel is calibrated)
These commands ensure that the analyzer is able to start a new measurement sweep.

ATTenuator
Calibration step, to be performed in the order RECeiver -> SOURce -> ATTenuator
(optional, if an external attenuator is used or if internal attenuators with different
attenuation values during calibration and during the measurement are used; see
[SENSe<Ch>:]CORRection:COLLect:NFIGure:STARt; corresponds to the
Attenuator Cal label in the Noise Figure Calibration dialog)
