【摘要】 使用网络测试仪能够方便地对地震数传电缆进行维修测试、检验等。其测试项目包括电阻测试、阻抗测试、接线图测试、长度测试,传输延迟、测试衰减、衰减串扰比测试,近端、等水平远端串扰测试,环路损耗测试等。本文简要介绍了一种网络测试仪LFLUKE DSP-4000的基本功能,使用该仪器测试几种常用数传电缆的技术指标以及在使用中的一些注意事项。更多还原

【Abstract】 Network tester can be used easily for seismic data transmission cable tests, such as resistance test, impedance test, wiring diagram test, the length of testing, transmission delay, testing attenuation, attenuation crosstalk ratio, level of proximal and distal cross-talk test, loop loss test.. Therefore, the network cable tester can be used for the maintenance testing. This paper introduces the basic functions of a network tester named LFLUKE DSP-4000′s and the method for testing several commonly used data specifications as well as some points needing attention in use.更多还原
