LMS Test.Lab MIMO FRF TESTING
Multi-excitation testing made easy – from time history replay to multi-sine
The new LMS Test.Lab MIMO FRF Testing extends the modal testing techniques already available in LMS Test.Lab Spectral Testing and Source Control. With this new solution, users can specify their specific excitation signals, define a shaped amplitude spectrum and extend the application to multi-sine excitation.
Periodic random excitation can be used to obtain the best linear fit for a non-linear system. When real-life excitations are preferred, users can simply record the time data and import it into LMS Test.Lab MIMO FRF Testing for replay. Before data replay, the time data and corresponding power spectral density can be visualized. Scaling and fading functionalities are fully integrated as well.
- Define excitation spectra with shaped amplitude for random and multi-sine excitation
- Use periodic random excitation for best linear fit for non-linear systems
-
Arbitrary source replay of several excitations in open
- Support of multiple sampling rate for acoustic signal and vibration signals
