A transducer to be tested is mounted on a shaking table which is energized by a desired driving test signal. The table's motion is precisely measured with reference to an inertial system, for example, a freely falling body. The precise measurement of the shaking table's movements is correlated with the electric output signal from the transducer, and the result of this correlation allows an accurate measurement of the characteristics of the transducer subjected to vibrations by the shaking table.
