Fast Fourier Transform Function
User can use the FFT mode to convert a time-domain signal into its frequency components (spectrum). You can use
the FFT mode for the following types of analysis:
To use the FFT mode, you need to click “Setup-> FFT” to open the FFT setting window.
The FFT setting window:
You can select the Source channel, Window algorithm, FFT number, and FFT Zoom factor. It displays only one FFT
spectrum at a time.
Source: Selects the channel used as the FFT source
Window: Selects the FFT window type
The windows reduce spectral leakage in the FFT spectrum.
