[:SENSe]:SPECtrum:FFT:LENGth:AUTO <bool>

(Read-Write) Set and query the FFT analysis length control. This setting is directly coupled to the resolution bandwidth as follows: Enabling Length Control (AUTO) enables the automatic resolution bandwidth setting. Disabling automatic Length Control (AUTO) to MANual, disables automatic Resolution bandwidth (i.e., Analysis length and resolution BW can be set manually).

See also, If the SPEC:FFT:WIND and SPEC:FFT:ANAL:LENG.
