EMA Modal Analysis

Once measurements have been collected, all saved data will appear in the Signal candidates for modal calculation tab. The tab can be filtered by the coordinate system used to define the testing location as well as filtering out for specific locations. The saved signals can be selected to view the FRF and response location on the geometric display. If Display, select signal is not enabled then the signals will overlay on the FRF plot. All saved data with the calculate modal check box enabled will be used in calculation of data.
