[SENSe<1|2>:]BANDwidth|BWIDth:DEMod
<numeric-value>
This command defines the demodulation bandwidth of the instrument for analog demodulation. The
required sampling rate is automatically set depending on the selected demodulation bandwidth.
The available demodulation bandwidths are determined by the existing sampling rates.

[SENSe<1|2>:]BANDwidth|BWIDth:DEMod
:
AUTO
ON | OFF
This command activates automatic setting of the demodulation bandwidth. The demodulation
bandwidth is set as a function of the operating mode (audio, AM, FM, PM, RF Level) in order to
minimize the measurement error in the specified measurement range.
Example:
"BAND:DEM:AUTO OFF"
Characteristics:
*RST value:
ON
SCPI:
device-specific
[SENSe<1|2>:]BANDwidth|BWIDth:FFT
AUTO | WIDE | NARROW
This command sallows to specify between the following three options for FFT filters.
AUTO:
The firmware decides whether to use wide or narrow filters to achieve the best
performance of the measurement.
WIDE:
The FFT filters with the greater partial span (this is the span which is covered with one
FFT analysis) are used always.
NARROW: The FFT filters with the smaller partial span are used, this allows measurements near a
carrier with reduced reference level, because of a more narrow analog prefilter.
Example:
"BWID:FFT:MODE WIDE"
Characteristics:
*RST value:
AUTO
SCPI:
device-specific
