摘要
在CATV系统中 ,同轴电缆仍然在提供用户的传送声音、图象和数据服务中充当重要的中介 ,为了提高整个系统的高效传输 ,电缆的测量是非常重要的 .汕头市有线电视台采用了HP871 1C代替老网络分析仪进行有线电视网络电缆的传输特性 ,反射特性等指标的测试 ,经过多次使用HP871 1C的测量 ,分析总结了测试中经常遇到的问题 ,介绍了电缆指标的测试技术 .
In the CATV system, cables still are the important linkman to provide the service of carrying sound, image and data. To improve the efficiency of the whole system, it is important for us to test cables accurately. Shantou CATV Station adopt HP 8711C instead of old network analyser to test the transmission and reflection character of cables. With analyses of the problems which have happened when we test cables, the author introduce the technique of testing cables.
