The Fourier Spectrum option in the Spectral menu or the Spectral toolbar offers a basic Fast-Fourier Transform (FFT) spectrum of the current data table. This option is the simplest of the Fourier spectral procedures. No data window tapering is available, there is no averaging of segments, and the data stream should be uniformly sampled (constant sample increment).
