ibaAnalyzer can carry out the spectral analysis in the form of the Fast Fourier Transformation (FFT). With the FFT operations available, a time or length based signal cannot only be displayed in FFT mode, but also made available as a calculated expression and used for further analyses.

For most of the functions described here, you can either display an amplitude or a power trend. This is indicated by the suffix "Ampl" or "Power" in the function names.
