摘要
A geophone testing apparatus includes a plurality of force detectors upon each of which is mounted a corresponding geophone. An electrical step function is applied to the active elements of the geophones to generate mechanical output transients. The mechanical output transients are detected by the force detectors which generate corresponding electrical signals. The signals are analyzed to determine the sensitivity, damping and natural frequency of each of the geophones under test. A multiplexer is provided so that all of the geophones may be tested at the same time.
