FFT

FFT is used to quickly perform Fourier transform on specified signals and transform

time domain signals to frequency domain signals. MSO2000A/DS2000A oscilloscope

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

Press MATH  Operate to select “FFT” and set the parameters of FFT operation.

Figure 6-1 FFT Operation

1. Select Source

Press Source to select the desired channel (CH1 or CH2).

2. Select Window Function

Spectral leakage can be considerably decreased when a window function is used.
