摘要
检波器测试仪是一种用于检波器直流电阻、自然频率、阻尼系数、灵敏度、失真度、极性等关键指标检测的物探专用计量仪器,其性能优劣直接影响地震采集数据的准确性。本文主要介绍了SNT-200这一新型检波器测试仪的设计原理、硬件组成、系统菜单;并通过与国内外多种型号检波器测试仪的技术指标、物理参数及测试性能进行对比,表明SNT-200检波器测试仪是检波器生产制造及野外检波器串参数测试的有效仪器。
Geophone tester is a kind of special measuring instrument used for the detection of DC resistance,natural frequency,damping coefficient,sensitivity,distortion,polarity and other key indicators.Its performance directly affects the accuracy of seismic data acquisition.This paper introduces the design principle,hardware composition and system menu of SNT-200,and comparing the technical indexes,physical parameters and test performance of domestic and abroad,SNT-200 is an effective instrument for detector manufacturing and field detector parameters.
