Keysight InfiniiVision HD3-Series Oscilloscopes User's Guide 4 FFT Spectral Analysis FFT is used to compute the fast Fourier transform using analog input channels or a lower math function. FFT takes the digitized time record of the specified source and transforms it to the frequency domain. When the FFT function is selected, the FFT spectrum is plotted on the oscilloscope display as magnitude in dBV versus frequency.
