Design and Implementation of Virtual Oscilloscope Based on PCI Bus

Weijun Zhao

Abstract

A virtual oscilloscope is made up of data acquisition,data analysis/processing and data display modules.This paper firstly represented the constitute,the principle and the accomplishment of the high rate acquisition card based on PCI bus,then the driver design,data analysis/processing,and data output/display in the software development were introduced.Finally,the virtual oscilloscope effect figure was depicted.
