R&S FSV-K7/K7S
The following table shows the required demodulation bandwidth for an error less than
0.5 dB up to a maximum AF frequency.

max. AF frequency
required demodulation bandwidth
For higher AF frequencies the demodulation bandwidth must be increased.
Remote command:
[SENSe:]FILTer<n>:DEMPhasis[:STATe]

All AF Filter Off ← AF Filter
Disables all specified AF Filters.
Remote command:
[SENSe:]FILTer<n>:AOFF
Demod Filter
By default, a flat demodulation filter is used in Analog Demodulation mode. However, in
order to optimize the settling behaviour of the filter, a Gaussian filter can be used
instead.
For details on sample rates, measurement times and trigger offsets for various demod-
ulation bandwidths when using a Gaussian filter, see
Measurement Time and Trigger
Remote command:
[SENSe:]BANDwidth:DEMod:TYPE
2.2.7 Softkeys of the Sweep Menu – SWEEP Key (Analog Demodulation)
The following table shows all softkeys available in the "Sweep" menu in "Analog
Demodulation" mode ([SWEEP] key). It is possible that your instrument configuration
does not provide all softkeys. If a softkey is only available with a special option, model
or (measurement) mode, this information is delivered in the corresponding softkey
description.
