To display the frequency domain using FFT

The FFT math function mathematically converts a time- domain waveform
into its frequency components. FFT waveforms are useful for finding the
harmonic content and distortion in systems, for characterizing noise in DC
power supplies, and for analyzing vibration.
To display a waveform's FFT:
1 Press [Math].

source waveform.
To reduce random noise and aliasing components (in repetitive or single-shot waveforms),
set the oscilloscope acquisition mode to averaging.
