线缆仿真器的校准方法研究

Research on wireline simulator calibration

由于国内还没有针对线缆仿真器的相关校准规范和检定规程,对线缆仿真器的校准就成为迫切需要解决的问题。利用阻抗转换器解决了线缆仿真器和网络分析仪的阻抗不匹配和连接端口不同的问题,使用网络分析仪测试线缆仿真器的插入损耗,通过实验确定了线缆仿真器的插入损耗的校准方法。对数据进行不确定度的评定分析证明了上述校准方法能达到校准线缆仿真器插入损耗的要求,为编制线缆仿真器的校准规范或检定规程解决了技术上的难题。

There is no calibration or verification procedure for wireline simulator in our country,so it becomes an urgent problem to establish a set of calibration procedures for wireline simulators.The impedance converter was used to solve the problems of impedance and connector mismatching between network analyzer and the cable simulator,and the network analyzer was used to test the insertion loss of the cable simulator.Then the calibration method of insertion loss was established for the wireline simulator on the ...
