[SENSe:]BANDwidth|BWIDth[:RESolution]:FFT
<FilterMode>
This command defines the filter mode of FFT filters by defining the partial span size.
The partial span is the span which is covered by one FFT analysis.
This command is only available for sweep type "FFT".
Parameters:
<FilterMode>
AUTO
The firmware determines whether to use wide or narrow filters to
obtain the best measurement results.
NARRow
The FFT filters with the smaller partial span are used. This
allows you to perform measurements near a carrier with a
reduced reference level due to a narrower analog prefilter.
*RST:
AUTO
Example:
BAND:TYPE FFT
Select FFT filter.
Example:
BAND:FFT NARR
Select narrow partial span for FFT filter.
Manual operation:

[SENSe:]BANDwidth|BWIDth[:RESolution]:RATio
<Ratio>
This command defines the ratio between the resolution bandwidth (Hz) and the span
(Hz).
Note that the ratio defined with the remote command (RBW/span) is reciprocal to that
of the manual operation (span/RBW).
Parameters:
<Ratio>
Range:
0.0001 to 1
*RST:
0.01
Example:
BAND:RAT 0.01
