FRF Acquisitions
With its dedicated structural mode, the FFT plug-in offers a comprehensive tool panel for FRF (Frequency Response Function) acquisition. Whatever the method used, impact testing with hammer or shaker excitation, FRFs are confidently acquired.

Main Features

Check the validity of the acquisition thanks to different displays and their preview:

Frequency Response Function
Trigger blocks
Averaged results

Excel based acquisition route and settings (Sequencer)
Accept/reject after averaging FRFs & Coherence
True Zoom on X-function up to 128 times
25 601 lines real-time results
Time domain averaged X-functions
Multi-mode generators: Sine, Swept, Step, Random, Multi-sine, Chirp, Wav
Smooth change generators: Phase & amplitude ramps, emergency shut-down
High resolution generators: 10 µHz from 100 µHz to 40 kHz
Up to 1000+ channels real-time acquisition (analysis + recording)
Impact testing
Adjust the settings using an appropriate weighted window if necessary: uniform, force/response, hanning…
Accept /reject the impact hammer measurement after validity checking
Hammer impact auto-range
Define the measurement sets in advance and use the node path sequencer to track all measurement points
The synchronous time domain averaging of impact signals allows acquiring the natural modes (FRFs, Coherence) of machinery without interrupting its operation (or any forced vibrations). This unique feature simplifies the natural resonance evaluation on diagnostic operations.
