Research, Experimental Platform Based On Pxi Bus Test System

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.
