Design And Realization Of Virtual Program Control Software Of DSO Based On VB

In this paper, the contents which reseach are through the computer main board and PCIexpansion of 54810A Digital Storage Oscilloscope, inserting the PCT-GPIB interface and into computer broad expansion, and through GPIB link computers and Digital Storage Oscilloscope. Using GPIB programmable commands and Visual Basic Programming software program control of it.Firstly, the paper introduces the research purpose and significance. Secondly, introducing the automatic test system develpoment process and the automatic test system construction, then introduced the GPIB bus interface and standard, hardware and driver installation and programmed some of the basic order, thirdly, with regard to the control object Agilent54810A Digital Storage Oscilloscope local operating and programming instructons made a simple introduction. then the ways and means of programming are introduced, and highlighting the introduction about the four programmed modules of Visual Basic software programming control: the system initialization module, the measuring function module, the continuous measuring module, and the saving and loading waveform function module. The ultimate platform is for building the entire system. Finally the papper introduces the application of sofeware and prove its practicality.The main point in the paper is that achieving 54810A Digital Storage Oscilloscope waveform automatic measurement parameters. Due to consider the two existential ways of waveform and non-waveform, separate procedures for the programming in the design, and then through many procedures to improve, we can achieve automatic waveform measurements and measurement data preservation. It gives convenience to analyse and conclude the data.The second and the forth chapters in this paper give the answers to the important questions which raised in the process of finishing this paper, which is mainly directed against the ifficulies n GPIB card installation(configuing GIPB) and programming, and then do the analysis and synthesis Currently, high-end experimental facilities were imported, most are equipped with a variety of interfaces for data communication. However, because of these devices use less, and most of them are used for local measurements, the development of remote communication sorely lacking, so that these furnishings have not been developed with staff are fully Deli Yong up. In addition, you can form a computer-control center, to connect multiple test instruments that can automatically complete the multi-point, multi-parameter, mass data storage and data post-processing features such as automated measurement system.In this context, the proposed research topic programmable apparatus is manually operated equipment to solve a protracted, inefficient, inaccurate. By Agilent54810A (100M) digital storage oscilloscope local operations, program-controlled equipment to master the basic concepts, basic principles; used widely used international standard GPIB interface to the hardware base, using the easy to learn and understand software as a programmable platform, Visual BASIC, and then by computer using IEEE488 interface card, GPIB cable, digital storage oscilloscope to complete Agilent54810A program control, computer and digital storage oscilloscope to achieve communication.
