analyzer speed.

FFT Width
This menudisplays and controls the width of the FFT’s performed while in FFT mode. The “FFT
width” is the range of frequencies being looked at by the FFT, sometimes referred to as the “chunk
width” -- it is not the resolution bandwidth used when performing the FFT.
It is important to understand that this function does not directly set the FFT width, it sets the
limit on the FFT Width. The actual FFT width used is determined by several other factors
including the Span you have set. Usually the instrument picks the optimal FFT Width based on
the current setup; but on occasion you may wish to limit the FFT Width to be narrower than that
which the instrument would have set.
This function does not allow you to widen the FFT Width beyond that which the instrument might have
set; it only allows you to narrow it. You might do this to improve the dynamic range of the measurement
or eliminate nearby spurs from your measurement.
Note that the FFT Width setting will have no effect unless in an FFT sweep.
