Due to the characteristics of its own moving-coil structure,the moving-coil geophone will inevitably produce and introduce various pulse oscillation and other jamming signals in the test,this paper through the de-tailed analysis of the tester's test DC resistance,damping coefficient,natural frequency,sensitivity,distortion and other process timing signals,focusing on the analysis of the signal attenuation characteristics of the damping attenuation oscillation signal when testing the damping coefficient,natural frequency and sensitivity.On this ba-sis,the problems that need to be paid attention to in the design,application and calibration of geophone test and tester are given.
