Dedicated acquisition interface Define the test setup in few clicks whatever the excitation: sequence, transducer definition, measurement and trigger parameters, interactive display, control panel. Geometry Building Interactive interface to create, modify, assemble standard elements or complex structure with global and local coordinate systems. Import from external software in universal file format. Direct acquisition and Signal processing Dedicated interface for modal with impact hammer acquisition, shakers or under operational conditions to obtain: FRF H1, FRF H2 for EMA Power Spectral Density, Half Power Spectral Density for OMA Broadband method for EMA & OMA With a clear stability diagram identify all the modes in the full frequency band at one time with high accuracy. Experimental Modal Analysis (EMA) Using an impact hammer or shaker(s), several identification methods allow one to determine modal parameters: frequency, damping and mode shape. Users can perform Single Input/Multiple Output (SIMO) method for a first approach and Multiple Input/Multiple Output (MIMO) techniques to make a more thorough analysis. Operational Modal Analysis (OMA) OMA is a very interesting technique for large structures or test items that are not easily excitable (e.g., civil infrastructures). With this method, modal parameters can be estimated without a known, controllable excitation signal.
