Abstract
A transducer test system for testing accelerometers or velocity transducers includes a signal conditioner and a shaker that can be used in a field environment, for example by an avionics technician at an aircraft. A test transducer and a reference transducer, which is a known-good version of the test transducer, are mounted onto the shaker and electrically connected to the signal conditioner. The technician shakes the two transducers simultaneously by manually shaking the shaker. The signal conditioner receives and compares the signals output from the test and reference transducer in order to determine the operating condition of the test transducer.
