基于DP105高速数据采集卡的虚拟示波器设计

本文基于Agilent公司的DP105型高速数据采集卡和PCI总线,采用LabVIEW图形化编程工具设计出一种快速虚拟示波器。实现了高速数据的采集和动态波形的显示以及传统示波器无法实现的频谱分析和数字滤波功能。同时,对设计实现过程中可能遇到的噪声和模拟信号的输出等问题,提出了相应的处理方法。

This paper Based on Agilent＇s DP105 high-speed data acquisition card and PCI bus,used LabVIEW graphical programming tools to design a fast virtual oscilloscope.Achieved function of the high-speed data collection and dynamic waveform display,and achieved spectrum analysis and digital filtering which the traditional oscilloscopes can not. At the same time,it supply corresponding manage method aiming at the problem of the noise and analog output and so on may be encountered, during the design and implementation.
