摘要
从光纤和微波信号、切换器、分配器、复用器、调制器、垫播信号方面介绍了河北地球站高清系统结构,分析了信号源输出及切换原理.在出现切换失败或切换设备故障的情况下,应采取跳线方案.
This paper introduces the processing of signal sources in Hebei satellite earth station, and puts forward a feasible jumper wire scheme between the existing signals and equipment. This scheme can deal with different equipment and source failures, thus ensuring the normal broadcasting.
