摘　　要：设计了一种适用于地面站微波测试系统中的信号传输开关网络。基于开关网络的拓扑结构设计,不仅可实现测量仪表对被测系统多测试点和多路径的接入,还可通过测试电缆分组环接测量再用方程组求解的方法,实现测试电缆方便而精确的标校。另外,开关网络可通过局域网远程控制,并能方便地集成在整个测量系统中。实际测试结果表明,该开关网络的设计具有很强的灵活性和可靠性。A switch network for signal transmission test is designed which is suitable for microwave test system in ground station. Based on the design of switch network topologic structure, not only multi - access connection is implemented between instrument and tested system but also test cable calibration is implemented easily and accurately by measuring looped cables group by group before solving equations. The switch network controlled remotely by Local Aera Network（LAN） can be integrated in the test system easily. The test results show that the design has strong agility and reliability.
