3.3 Spectral Analysis
In the spectral analysis page, the fast Fourier transform (FFT) of the data capture is displayed. Because of the nature of an FFT, the minimum number of samples for accurate measurements is 32768. As shown in Figure 3-3, select any sample number count of 32768 or larger in the drop down for Samples.
