FFT

FFT is used to quickly perform Fourier transform on specified signals and transform
time domain signals to frequency domain signals. The DS2000E series provides FFT
operation function which enables users to observe the time domain waveform and
spectrum of the signal at the same time. 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
