PXI示波器模块的软件设计

内容简介：本文结合虚拟仪器的发展现状及市场对高性能模块化仪器的需求,研制了PXI示波器模块。简单介绍了模块的硬件工作原理,详细描述了利用VC＋＋6.0和LabWindows/CVI开发底层驱动和应用程序界面的过程及实现。经测试表明,该示波器模块在实现传统示波器功能的基础上,大大提高了数据处理和显示的性能。底层驱动实现了对PXI模块的控制和操作,完成了数据采集、参数测量、波形分析、波形显示等功能,满足了用户对示波器基本功能和对信号高速采集及处理的要求。

Abstract：In this paper, combining with the development situation of virtual oscilloscope instrument and the market demand for high-performance modular instruments, the PXI oscilloscope module is developed. It simply introduces the working principle of hardware, and then detailed description of the development and the realization of hardware driver and API using VC＋＋ 6.0 and LabWindows/CVI. The test results indicate that the oscilloscope module not only implemented the traditional oscilloscope functions but also improved the performance of data processing and display, and that the driver implements the equipment control and operation and completed the data acquisition, parameter measurement, waveform analysis, waveform display and other functions. So it can meet the user’s oscilloscope basic functions and high-speed signal acquisition and processing requirments.
