宽带有线电视网输出口电平前端测量的实现

The Measurementof Output Level in Broadband Transmission CATV Networks at Headend

本文描述了在双向有线电视宽带传输网络中实现在前端进行输出口电平检测的方法。设计中采用先进的 PIC单片机作为测试终端主控制器 ,并利用其特点 ,在保证测量精度需要的前提下 。

This paper briefly describes the method to measure the output level of broadband transmission CATV networks;and in the design,the advanced PIC microcontroller is used as the master controller of the ter- minal measure unit.Under the promise of adequate measure precision,we try to reduce the cost of hardware.
