本文介绍了一种基于PXI 总线的高速信号发生器的设计理论和实现方法，从硬件和软件
两个方面详细介绍了系统的设计方法。该平台基于高速数模转换器MAX5887 和高性能可编程逻辑器件VIRTEX-4 SX35，可以实现500Msps 的转换率和14 位的分辨率；接口上采用PXI总线技术，采用PCI9054 作为接口芯片；软件开发上采用DLL+API 的模式，方便不同用户的定制。

Abstract This article introduced a design principles and implementation method of a
high-speed signal generator based on PXI bus technology. It described the system
composition from hardware and software. This platform is based on high-speed DAC
MAX5887 and high performance FPGA—VIRTEX-4 SX35, and it realized 500Mhz update rate
and 14 bit resolutions; PCI9054 are used as interface IC for PXI bus; DLL+API mode
are used in software development, convenient for different user’s customization.
