FFT

FFT is used to quickly perform Fourier transform on specified signals and transform
time domain signals to frequency domain signals. FFT operation can facilitate the
following works:
Measure harmonic components and distortion in the system

Measure the characteristics of the noise in DC power

Analyze vibration

Press MATH  Math  Operator to select "FFT" and set the parameters of FFT
operation.
