FFT
The FFT (Fast Fourier Transform) operation can transform time domain signals to
frequency domain signals (frequency spectrum). FFT operation can facilitate the
following works:
Measure the harmonic components and distortion in the system
Measure the characteristics of the noise in DC power
Analyze the vibration
MSO4000/DS4000 provides the FFT operation function which enables users to view
the time domain signal and frequency spectrum at the same time, as shown in the
figure below.

You can perform the FFT operation following the steps below.
1. Select the FFT operation
Press MATH Operate, turn the multi-function knob to select “FFT” and
press the knob. You can also press Operate continuously to switch to the “FFT”
operation.
