    Using FFT function The FFT (fast Fourier transform) math function mathematically converts a time-domain waveform into its frequency components. It is very useful for analyzing the input signal on Oscilloscope. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies. FFT function in this oscilloscope transforms 8192 data points of the time-domain signal into its frequency components mathematically (the record length should be 10K or above).
