You can only select RBW filter in SAT mode.
The RBW (Resolution Bandwidth) filter function determines the bandwidth of the bandpass filter,
which is used to generate the spectrum of the input signal (IF).
This bandpass filter works like a window: the smaller the bandwidth, the more detailed is the
representation of the spectrum. However, a smaller value RBW provides a slower refresh rate of
the spectrum
You can choose (high resolution, slower refresh rate) between the RBW filter between a
bandwidth of 1 MHz or 5 MHz (lower resolution, fast refresh rate).
