摘　　要：在某些雷达对抗试验中,为了精确地评估试验效果,设计了一个高速信号采集系统,该系统具有最高为500 MS/s的采样率,板上缓存为1 GB,同时提供与高速存储系统的数据传输接口以供外扩存储容量。该系统提供了示波器工作模式和连续采集工作模式两种工作模式,用户可根据需求使用不同的工作模式对采集到的数据进行处理,同时该系统具有完善的触发功能,以方便用户对数据进行分析。In some radar countermeasure tests,a high-speed signal acquisition system was designed to assess the test results accurately. This system has the maximum sampling rate of 500 MS/s,in which the cache in the card is 1 GB,and can provide data transmission interface of high-speed storage system to expand the storage capacity. Two operation modes of the scope operating mode and the continuous acquisition mode are offered in this system,and users can use the different operating modes according to the requirements to process the collected data. This system has perfect trigger function,and is convenience for the users to analyze the data.
