摘　　要：有线电视网作为宽带传输网,具有带宽高、性能价格比优、覆盖范围广等特点,是理想的综合业务网。为了对现有的上海有线电视网系统进行性能的评定,并给未来双向多功能有线电视网的进一步扩展提供依据,上海有线电视台和上海交通大学采用LANCity系列产品进行了一次满负载试验。该试验的结果分为两大类:数据流量信号的测试结果和RF信号的测试结果。文中详细讨论RF信号测试结果的分析。As the wide-hand transmission network, Cable TV Network has the advantage of wide band, high performance-to-price, wide cover area and so on. In order to test the performance of Shanghai Cable TV Network System, and also to get some basis for developing a high performance bi-directional RFC network, Shanghai Cable TV Station and Shanghai Jiaotong University used LANCity serial productions to afford an experiment. The experiment includes two parts.First one is the test of digital signal throughput, and the second is the test of RF signal.This paper provides an overview of the second part and gives some analysis about the data in the second part.
