General > IF Frequency ← Advanced Settings
For typical applications, the IF frequency is chosen automatically and depends on the
chosen Noise Bandwidth and the measurement frequency. However, for certain mea-
surements it can be preferable to choose a different IF frequency. The manually
chosen IF frequency is applied over the full measurement frequency range.
Remote command:
[SENSe<Ch>:]NFIGure:IFConst
[SENSe<Ch>:]NFIGure:IFConst:STATe
General > Ambient Temperature ← Advanced Settings
The ambient temperature is used for precise calculation of the source noise tempera-
ture at the input of the DUT. The external attenuation (cables, adapters, attenuators,
etc.) is assumed to have a physical temperature equal to the ambient temperature.
See "Source noise temperature" on page 291 for a detailed description.
Remote command:
[SENSe<Ch>:]NFIGure:TEATtenuator
General > Virtual Image Rejection ← Advanced Settings
If "Virtual Image Rejection" is active, the firmware combines different measurements to
remove the image band influence, which allows precise measurements of narrow
spikes on "Noise Figure", "Gain" or "Noise Density" traces. By default it is disabled.
For segmented sweeps, virtual image rejection can be activated or deactivated per
segment (see "Optional Columns" on page 557).
Remote command:
[SENSe<Ch>:]NFIGure:VIRejection[:STATe]
