摘要
基于PCI接口的CompuScope82G型高速数据采集卡和VisualC++编程工具,设计了一种快速虚拟示波器试验系统,为了保证数据采集和波形显示的实时性,设计中采用了多线程技术。该系统集波形采集、数据分析、输出、显示为一体,实现了高速数据的采集和动态波形的显示,并且在此基础上实现了传统示波器无法实现的频谱分析和数字滤波功能。
A new fast virtual oscilloscope system was designed by using Visual C ＋＋ programming tool and the ultra-fast PCI oscilloscope card CompuScope 82G.The multi-line technique was used for speeding the data acquisition and data processing.The software modules for data capturing, analyzing, processing and displaying are designed with integration.The system realized the functions of capturing fast data and displaying the real-time waveform. Further more, it is able to realize the functions of FFT and digital filter which the traditional oscilloscope couldn＇t accomplish.
