摘　　要：采用标准化的总线技术和软件技术开发的自动测试系统功能强大、通用性强,便于系统的集成化设计。基于PXI总线技术,提出了在VC++6.0环境下调用LabWindows/CVI生成的动态链接库对NI的PXI-5152示波器模块进行控制的方法。通过此方法实现了虚拟数字示波器的设计,经测试证实该虚拟数字示波器测量精度高、功能完善,达到了设计要求。采用上述方法还可开发三用表、频谱仪等虚拟仪器并已应用在某集成化测试系统中。Automated test system developed by Standard bus and software technique is powerful, unified and good for system＇ s integrated design. Based on PXI bus technology, a method is put forward in order to control NI＇s PXI-5152 Oscilloscope module in VC ＋ ＋6.0 environment calls a dynamic link library which LabWindows/CVI generated. By using this method we complete designing a virtual digital oscilloscope which is confirmed with high measuring accuracy, fully functional through test, meet the design requirements. We also can develop other virtual instruments such as multimeter, spectrum analyzer, these instruments have been applied in a integrated test system.
