广播电视卫星地球站的系统设备及测试监控探讨

随着全球广播电视全面向网络化、数字化进发,广播电视节目从制作、播控、发送到接收都将逐渐全面数字化,并可对各环节进行必要的网络实时监控,从而保证性能可靠性的提高和处理环节的智能化。卫星通信地球站主要构成设备有天线设备、高功率放大设备、低噪声接收设备、变频设备和相应的调制解调设备所构成。本文就典型的广播电视卫星地球站的系统设备及测试监控系统的基本要素进行了探讨。

Radio and Television Satellite Earth Station Equipment and Test the System of Monitoring

As to the overall global radio and television network, and towards digital, radio and television programs from the production, Studio, will be sent to gradually receive full digital, and all sectors of the necessary real- time monitoring network, thus ensuring the relia- bility of performance enhancing And intelligent handling of the link.Satellite communications earth station equipment is a major antenna equipment, high- power amplification equipment, low- noise receiver equipment, frequency conversion equipment and the corresponding modem posed by the equipment. In this paper, typical of radio and television satellite earth station equipment and test the system monitor- ing system the basic elements were discussed.
