摘　　要：随着测试技术的发展,对信号的要求越来越高,高采样率任意波形发生器被广泛应用于各种测试系统中。文章重点介绍了在PXI3U板卡上实现采样率高达200MS/S的任意波形发生器模块的设计。设计中采用QDRII代替了SRAM,解决了由于存储器带宽过小而阻碍任意波形采样率提高的问题。With the development of measurement technology, the requirement for signal is more and more higher. Arbitrary Waveforrn Generator which has higher sample Js widely used in various of measurement system, Jn this article, the design of Arbitrary Waveform Generator on PXI 3U board was introduced, Which samples achieved 200MS/S. In the designment, the SRAM has been replaced by QDRⅡ. resolving the problem which induced by the bandwidth of memory, because of it is too narrow to heighten the sample Of Arbitrary Waveform Generator.
