摘　　要：HFC（hybrid fiber coaxial）双向网络逐渐成为我国有线电视系统的主导。文中设计了一种基于DSP处理器的HFC网络信号监测系统,在不改变网络运行状态的情况下,对HFC网络多路用户的5~65M反向通道进行实时频谱分析并通过网关将数据结果传送到机房端。管理人员最终可以从内部联网的任一计算机上得到所有回传通道信号的特性参数和相应的波形数据,无需跑到远程站点即可实时检测HFC网络信号。HFC network has been gradually become the dominant of cable television system in China. This paper designs a DSP-based processor of the HFC network signal monitor system, without changing the network running the circumstances,the HFC network multi-user 5-65 M reverse channel spectrum analysis and real-time data through the gateway send the results to the engine room side. Management staff can eventually get the parameters and corresponding waveform data of all the back-channel signals from any computer in the internal network. So they can detect the HFC network signal real-time without going to the remote site.
