Huang Zhen-xian

Abstract

In order to meet the current status of the widely used USB interface,the data acquisition card USB-6008 made by NI company was studied,its hardware architecture was analyzed,the design process and block diagram of the virtual oscilloscope based on USB interface was given,and the actual measurement was applied.At the premise of technical parameters of the data acquisition card,virtual oscilloscope can achieve the same accuracy as ordinary oscilloscope.In the fields such as file storage and data calculation,virtual oscilloscope has more obvious advantages.
