Abstract
Systems and methods for automated MIMO force-response characterization of a device/structure-under-test. A SIMO exciter router is operated to selectively couple an excitation signal input to an exciter device while the sensor data indicative of a sensed response to the imparted excitation force is collected from a plurality of response sensors. The SIMO exciter router operates to collect sensor data for each of a plurality of different exciter-sensor combinations (i.e., sensor data is collected from each individual response sensor while the excitation force is applied by each individual exciter device). The sensor data is collected by a data acquisition system with a plurality of signal input channels each coupled to a different response sensor or a sensor router is used to selectively couple each individual sensor output to a shared signal input channel of the data acquisition system.
