Structural Acquisition with NVGate (FFT)
Overview
With its dedicated structural mode, the FFT plug-in offers a comprehensive tool panel for FRF acquisition. Whatever the method used, impact hammer or shaker excitation, FRFs are confidently acquired.
Check the validity of the acquisition thanks to different displays and their preview:
- Frequency Response Function
- Coherence
- Trigger blocks
- Averaged results
Main Features
- Excel based acquisition route and settings (Sequencer)
- Accept/reject after averaging FRFs & Coherence
- True Zoom on X-function up to 128 times
- 6400 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 320+ channels real-time acquisition (analysis + recording)
Impact testing

 | Shaker excitation with generators For exciting a large structure, up to 6 shakers can receive signals from the generator outputs of the analyzer. In order to fi t the wide range of potential cases, a large series of excitation signal such as swept sine, chirp, random, etc. can be simultaneously generated. Any channel can be set as the reference which generates a multiple reference FRF and cross spectrum matrix. |
Large channel count: VibeMasterLarge structures require a high number of input channels. With VibeMaster, multiple OROS analyzers can be cascaded to increase the total channel count. This solution offers the same acquisition, recording and analysis capabilities as 3-Series analyzers on wider scale applications..
