The S2-FFT software (Software Solution for Fast Fourier Transform) has been developed for field analysis of the collected signals in the time as well as frequency domain.
In particular, the user can inspect the collected time series, apply a window, filter the signals, compute the Fast Fourier Transform and plot its amplitude and phase, pick the dominant frequency components, and check the signal for stationarity. It is a simple but effective tool for a preliminary analysis of signals collected in the field, including vibration measurements and monitoring of the dynamic response of structures. Different file formats can be used (*.tdms, *.lvm, *.uff, *.unv, *.csv, *.txt).
