Fourier Analysis of Spectra

Command: Tools > FFT of Spectra

The command Tools > FFT of Spectra allows analyse the spectral components by applying a Fast Fourier Transform (FFT) on the signal. Moving the mouse cursor in the image selects the corresponding pixel and analyses its spectrum. The results of the FFT are displayed as spectrum and available in tabular form as well.

How to:
  1. Select the spectral resolution.
  2. Select the type of the spectrum to be displayed. Please note that the tabular form always lists all types of spectra, independent of the selection.
  3. Select a weighting window.
  4. If the signal is shorter than the selected spectral resolution select the type of padding.
  5. If the dataset contains more than one spectrum, select the desired part of the data.
