3-16 RF filter bandwidth for A/D converter

AB ABn
This command is used to select the bandwidth of analog filter for the A/D
converter. Normally, it should be set to 10MHz. However, in case of a strong
signal in adjacent frequency, it can be set to 30kHz. This setting does not affect
spectrum display function or FFT search.
