在PC机上实现基于PCI-9812的高速连续采集

Implement High-speed and Continuous Acquisition Using PCI-9812 in PC

介绍了PCI-9812高速数据采集卡的硬件特征及性能,特别是对该卡的数据流进行了详细分析,给出了在PC机上高速连续采集的方法,并以C++类实现了对该卡采集功能的封装,解决了在PC机上以高采样率采集出现掉点的问题。

This paper introduces the hardware feature and performance of the PCI-9812 high speed simultaneous-sampling analog input card,emphasizes the analysis of the data flow in detail,gives a solution to implement continuous,high-speed and reliable acquisition in PC,details a C＋＋ class which encapsulates the acquisition function,solves a problem of losing samples when using high sample rate in PC.
