Most of the vibration phenomena have to be analyzed in the spectral domain in order to get conclusive analyses. The FFT Plug-in provides spectral analysis associated with some time domain parameters. This software option offers a large set of results (up to 42) featured by the multiple available modes. FFT plug-in allows fast and accurate analysis for general purpose vibrations plus some dedicated modes.

FRFs : Impact hammering or shaker excitation, the FFT plug-in acquires and computes cross functions between any and all channels. On-line displays let you evaluate averaged coherences and accept or reject the acquisition.
Synchronous time averaging reveals faults buried into noisy signals coming from rotating machinery. STA can also automatically synchronize its phase from spectral information with the FDSA averaging
FFT Zoom and envelope offers a unique multispan spectrum analysis by simultaneously providing wide band spectra, zoomed spectra and demodulated envelope signals.

Customize your display with the comprehensive set of complex spectra representations. You can swap from polar to phase/module in one click.
