摘　　要：针对传统的地面测控测试设备结构复杂、可移植性差、难以满足当前测试要求的现状,提出了基于CPCI总线设计的卫星PCM测控测试设备。设备采用"通用前板+专用背板"板卡设计方法,提高通用性,降低成本;使用FPGA代替传统分立元件,提高设计效率和可靠性。为便于调试,硬件功能尽量简化,只完成数据发送接收操作,遥测帧同步、遥控指令解析等工作由软件实现。Traditional ground test equipment with problems of complex structure and difficult to transplant, can not suitable for current test requirements. To solve such problem, a new kind of PCM instrumentation channel test equipment based on CPCI bus was referred. The equipment adopted ＂universal front card ＋ special back card＂ design to enhance general and reduce cost, and used FPGA to replace separate components to enhance efficiency and reliability. Hardware charged for data transmitting and receiving, and software charged for telemeter frame synchronization and telecontrol.
