The present disclosure relates to a system for measuring a dynamic response of a machine. The system includes a vibration mechanism, an accelerometer, a controller and a casing. The vibration mechanism is operable to generate an excitation signal, and the accelerometer is operable to measure dynamic energy in response to the excitation signal and output a dynamic response signal indicative of the dynamic energy. The controller includes a communication interface and operates the vibration mechanism to output the excitation signal and transmit a vibration input signal based on the excitation signal by way of the communication interface. The casing houses the vibration mechanism and the controller.
