Zusammenfassung:This invention relates to an automatic method and apparatus for quick and convenient testing of one or more geophones of a geophysical data acquisition system through the generation and analysis of the impulse response characteristsic of such geophones. In particular, geophone response characteristics related to first and second adjacent absolute peak amplitudes associated with the damped equation of motion of the geophone coils are detected and digitally indicated in a surprisingly accurate manner, irrespective of whether or not the testing is carried out in a laboratory or field environment.
