摘　　要：针对脉冲变换器特殊的测试任务,以FPGA为核心,详细介绍了脉冲变换器测试系统的设计方案。该系统通过USB实现与计算机的通信,能够产生7路28V脉冲信号,完成4路模拟信号的采集,并能以PCM码的格式发送和接收数据。测试系统完成了对脉冲变换器各项功能的测试,是脉冲变换器在生产、调试过程中的唯一评价手段。According to the special test assignments of the impulse converter, this paper, taking FPGA as the core, detailly introduces the design scheme of test system of impulse converter. The system which communicates with the computer through USB is able to produce seven-channel impulse signals of 28V, complete sampling four-channel analog signals, and send and receive data by format of PCM code. The test system has completed all the test assignments of the impulse converter. And it is the only evaluation means in the production and debugging process of impulse converter.
