【摘要】 本文在研究PXI总线，虚拟仪器技术的基础上，将此技术应用于学科建设项目，开发了基于PXI总线的测试系统实验平台。本文首先阐述了PXI总线技术及图形化编程语言LabVIEW的特点以及整个测试系统实验平台的结构及功能。接着着重论述了利用LabVIEW和基于PXI总线的各种模块化仪器，开发诸如虚拟示波器、任意信号发生器、数字万用表，频谱分析仪等虚拟仪器的方法及实现过程。文中还列举出了这些虚拟仪器设备的应用实例。在此基础上，应用这些虚拟仪器设备，设计开发了信号处理课程的相关实验。学生通过在实验平台上进行实验，可以加深对课本理论知识的理解，提高动手能力。最后介绍了NI的DateSocket技术，阐述了实验平台网络化的实现方法和远程实验平台的功能。远程实验平台的建立为实验室建设节省了大量资金，提高了实验水平。更多还原

【Abstract】 Based on the research of PXI bus and virtual instrument, the thesis applies the technology in the project of subject constructing and develops the experiment platform of testing system on PXI. This thesis expatiates on the technology of PXI, the characteristics of the Lab VIEW, a development environment based on graphical programming, and the structure, functions of the experiment platform. And then this thesis mainly discusses the methods of developing virtual instrument such as digital scope, arbitrary waveform generator, digital multimeters, spectrum analyzer, with LabVIEW and modularization instruments based on PXI. Many applications and examples of using these virtual instruments are illustrated. Based on these virtual instruments, many experiments about the course of signal processing are designed. Trough making these experiments, students can understand theory on the courses more deeply, and develop the practice ability. At last, the technology of DataSocket, developed by National Instrument, is introduced. This paper also discusses the realization and function of the remote experiment platform, which not only saved the cost of establishment of the laboratory, but also improved the experiment teaching.更多还原
