With its dedicated structural mode, the FFT plug-in offers a comprehensive tool panel for FRF acquisition. Whatever the method used, impact testing with hammer or shaker excitation, FRFs are conﬁdently acquired.
Check the validity of the acquisition thanks to different displays and their preview:
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 structures require a high number of input channels. Multiple OROS analyzers can be cascaded and distributed to increase the total channel count and measure up to 1000 channels. Thanks to the OROS Teamwork technology, instruments, conditioners and software licenses are exchangeable and flexible, as well as data which benefit from a native sharing technology.
