The FFT analysis test acquires sampled amplitude data from a single probe in the time domain and converts the data into the frequency domain. A graph of amplitude vs. frequency is produced. The graph is updated once per second, showing the FFT results on the most recent data set. FFT data is used in identifying bearing frequency, adjacent machinery frequencies and the like.
