Page 191: Frequency Analysis
SDS3000X HD Series Digital Oscilloscope User Manual 20.5 Frequency Analysis The result of FFT (Fast Fourier Transform) calculations is the frequency spectrum of the source signal. The horizontal axis of the FFT display is labeled using frequency (Hz) units instead of time (seconds).
Page 192 SDS3000X HD Series Digital Oscilloscope User Manual  When N is greater than 2 Mpts, FFT first decimates N by D and then takes the first 2 Mpts for the calculation. In this case, FFT sample rate = sample rate in time domain/D.
Page 193 SDS3000X HD Series Digital Oscilloscope User Manual For example, for a two-tone signal with a very close frequency interval, it is suitable to use a Rectangle window with the best frequency resolution. For the case where the accuracy of amplitude measurement is critical, it is recommended to select the Flattop window with the best amplitude resolution.
