| 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. |
