Several custom tools are included to demonstrate how different FFT calculations can be created and saved as custom tools.



FFT with averaging


This tools calculates FFT Magnitude with averaging option turned on, splitting signal in 10 segments with 25% overlap, calculating FFT, and averaging the results

Welch's periodogram


Basically the same as FFT with averaging, except Power Spectrum Density is calculated instead of Magnitude

FFT normalized and smoothed


This tools calculates FFT with some options turned on: removing linear trend and peaks from the input signal and smoothing FFT result with a 15 samples long moving average. filter, removing peaks outside

FFT smoothed


Similar as the previous one, but without operations on the input signal.

FFT with 3D and max marker


This tools calculates FFT by using default settings and creates two more windows: one instrument window displaying a dominant frequency from the FFT, and a second one for tracking all calculated FFTs in a 3D graphic.



FFT with max marker and max tracking


This tools calculates FFT by using default settings and creates two more windows: one instrument window displaying a dominant frequency from the FFT, and a second one tracking all max. frequency values in a signal.




FFT with max marker


Similar as a previous tool, but without tracking max. frequency values.
