摘　　要：针对现有的信号发生系统在波形产生、通道数及工业现场使用等方面的局限性,设计了一种基于PCI总线、TMS320VC5409A、CPLD及光纤模块的多通道任意信号发生系统;系统利用PC机作为主控,通过PCI总线和板卡进行数据交换,再由光纤模块将数据发送到DAC阵列完成数模转换,同时产生用户自定义的逻辑信号,达到生成多通道任意信号的目的;经过在目标模拟器等实践中的成功应用,证明了系统的设计达到了预期的要求,也验证了设计思想的正确性。Aimed at the limitation in application of the existing signal generating system, a multi-- channel any--waveform signal generator based on PCI bus, TMS320VC5409A, CPLD and optical module was designed. The system uses the PC as the main control center, does data exchange with card through PCI bus, and sends data to the DAC array by optical module, then completes the conversion and generates the user define logic. The successful application in target simulation proves that the design has reached the expected requirement, and the ideal of design is correct.
