CALCulate:TRANsform:FREQuency[:STATe] ONCE
Description
Initiates a single calculation of the frequency transform (spectrum), i.e. the instrument
calculates spectrum only upon receipt of this command. An attempt to perform the
spectrum calculation while SENSe:SWEep1[:STATe] is ON (memory storage of samples)
will generate error "-221, Settings conflict".

CALCulate:TRANsform:FREQuency:MODE FFT | DFT
Description
Selects the harmonics calculation method.
Parameter(s)
FFT Calculates an FFT amplitude spectrum. Number of lines is determined by the
instrument and depends on the stop frequency, anti-aliasing filters setting and
instrument model.
DFT Calculates a DFT amplitude spectrum, i.e. the amplitude of the calculated
fundamental frequency and its integer multiples. Number of lines (harmonics)
is always 41 including the DC component.
