模数混传有线传输系统的通道调试

Channel Debugging of Analog-to-digital Hybrid Cable Transmission System

在分析模拟电视和数字电视信号各自特点的基础上,提出一种采用常规的测试仪器进行模数混传有线传输系统的通道调试方法,并且在实际网络中进行了测试,对测试结果和数据进行分析总结。

Based on the analyzing of the features of analog TV＇s and digital TV＇s signal, this paper presents a debugging method with common testing instrument in the analog-to-digital hybrid cable transmission system. It gives a test in the real network, and then summarizes the result and data.
