At what RBW/Span does the FFT automatically turn on? In Auto-Couple mode, FFT mode will automatically turn on at spans <=200kHz, and RBWs <=300Hz. The user may choose to use FFT mode of regular swept measurements in any span or RBW setting through the Mode Setup menu to tradeoff speed and dynamic range/accuracy as desired.
