Open publisher page 1 citations

Abstract

An ultra-high speed data acquisition card which c an sample and transmit data continuously is studied.A 800MHz,14bits data acquisition system is carried out by using two 400MHz、14bits data acquisition modules.The PCIe in-terface based on the Xilinx FPGA IPCORE is introduced.The method of fast band switching is used for data transferring,then the ability of long time data sampling and transmitting is achieved.The data acquisition system based on the card can be used in many aspects such as radar counterwork.
