摘　　要：为解决战略预警雷达、舰载一体化等重点型号雷达中高速数字电路模块的维护能力,设计了基于VPX总线的高速数字电路自动测试系统,通过自研基于VPX总线的多功能测试模块、光纤测试模块,以及通用VPX背板,再结合通用的仪器设备构建测试系统,可兼顾多个型号雷达高速数字电路模块的测试;该系统可提供10路光纤通道,波特率最高为3.2Gbps;16路GPIO信号,中断响应时间<50μs;14路Rocket IO信号,传输速率2.5Gbps;4路*4Rapid IO信号,传输速率3.125Gbps;研究及实测结果表明该系统可解决基于VPX总线的高速数字电路模块的测试。An automatic test system of high speed digital circuit based on VPX bus is designed in this paper to resolve maintenance abilily of high speed digital circuit modules in the important strategic early warning radar and shipboard integrated radar. The system can test high speed digital circuit modules of multiple model radars. We establish the test system by researching muhiple function test module, fibre-- optical lest module and universal backboard based on VPX bus, universal instruments are also used in the system. The system can provide ten fibre--oplical channels which the highest transport frequency is 3.2 Gbps; sixteen GPIO signals which interrupt response time is less than 50 μs; fourteen Rocket IO signals which transport frequency is 2.5 Gbps; 4 ＊ 4Rapid 10 signals which transport frequency is 3. 125 Gbps. The research and test results show the system can resolve the test problem of high speed digital circuit modules based on VPX bus.
