Open publisher page 1 citations

Abstract

A set of high-sampling rate,long-term data acquisition and analysis system based on the virtual instrument LabVIEW and the high-speed digitizer NI PCI-5124 is designed in this paper.The system has 20MHz sampling rate or even higher,it realizes the multiple function of real-time signal acquisition lasted minutes,real-time storage,playback,signal analysis,report form printing,etc.The experiments show that:this design proposal takes some advantages of easy programming,high versatility,good transplantation,simple interface design,easy operation,and so on.
