摘　　要：为提高训练效果,仿真训练系统中需进行信号波形测试。在介绍PCI1721板卡基本功能及主要特点的基础上,介绍了VB编程结合PCI1721总线扩展实现信号产生的方法,给出了信号产生软件实现的基本方法、PCI1721实现多通道输出的方法以及VRML和VB交互的实现方法,便于以后功能扩展。为保证输出波形满足要求,实现脉冲信号、视频信号、检波信号等模拟信号的选择输出,设计了整形电路。这样既可以实现虚拟测试又可以实现真正测试。In order to advance training effect it is required to test signal. The performance and characters of PCI1721 are introduced. The method of signal test bases on VB program combined with PCI1721.The basic method of software design is given. The method of multicenter output and alternating between VRML and VB are carried out .In order to ensure the real need and the out choice of analog signals, the plastic circuit is designed. Not only virtual test is implemented but also real test.
