Abstract

Relying on the data acquisition,computer conducts signal analysis and processing.While the existing data acquisition card is high cost,interface complex,and hard to expand.Using a hardware platform which regards USB controller and FPGA design as the core of the system,combining the user application program designed by LabVIEW and USB driver by NI-VISA,the design of high speed data acquisition system is realized at last.According to the test result,the system with high integration,flexible structure which is easily expanding,reaches a reliable transmission speed of 30 Mbit/s.
