In the world of vibration calibration there are some major components of the measurement system that require accurate, annual, traceable calibration. These include major components like the data acquisition system (either DSA in modern systems or meter based in older systems), the reference and sensor-under-test (SUT) signal conditioning, and the vibration reference transducer itself. The units are the backbone of the integrity of a vibration calibration system and typically undergo daily system validation with a known vibration sensor in addition to receiving rigorous environmental (both handling and environment) control, as well as annual component recalibration.
