摘　　要：动圈式检波器由于自身线圈结构的特点,在测试中不可避免会产生和引入各种脉冲振荡等干扰信号,本文通过对测试仪在测试直流电阻、阻尼系数、自然频率和灵敏度、失真度等过程时序信号的详尽分析,重点分析了其测试阻尼系数、自然频率和灵敏度等三项参数时阻尼衰减震荡信号的信号衰减特征,在此基础上给出了检波器测试和测试仪设计应用及校准中需要注意的问题。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 detailed 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 basis,the problems that need to be paid attention to in the design,application and calibration of geophone test and tester are given.
