als 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.
FFT in this oscilloscope can transform 2048 points of the time-domain signal into its frequency
components and the final frequency contains 1024 points ranging from 0Hz to Nyquist frequency.
