Data Acquisition and Signal Analysis Based on LabVIEW and Homemade A/D Board
【摘要】 介绍通过调用动态连接库,在LabVIEW环境下,利用国产模入卡KPCI-814实现数据采集的方法.利用混有噪声的模拟信号,采用LabVIEW自带工具包实现了信号的数字滤波与频谱分析.系统将为超导量子干涉器(SQUID)在弱磁场测量中的应用提供良好的信号采集、处理与分析手段.
【Abstract】 <Abstrcat> On the platform of LabVIEW, using homemade KPCI-814 A/D board, the method by calling dynamic link libraries to carry out data acquisition is introduced. By using the tool packages in LabVIEW, the spectrum analysis and digital filtering for simulated signal with noise is realized easily. The system can provide good tools for data acquisition, processing and analysis for superconducting quantum interfere device (SQUID) used in weak magnetic field detection.
