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 Coherence Trigger blocks Averaged results Features 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.
