Analyze Waveform Data
Using FFT
An FFT breaks down signals into component frequencies, which the oscilloscope uses to display a graph of the frequency domain
of a signal, as opposed to the oscilloscope’s standard time domain graph. You can match these frequencies with known system
frequencies, such as system clocks, oscillators, or power supplies.
