Res BW

Enables you to set the resolution bandwidth setting. This is the resolution bandwidth of the FFT analysis.
Changing this value changes the FFT Window size, FFT length and the sweep time (measurement
capture length).
If FFT Length Ctrl in the FFT Size menu under Meas Setup, Advanced is set to Manual, the Res BW key
is grayed out and shows the resolution bandwidth determined by the FFT Window size.
If the function is auto-coupled, the value setting is ignored.
