摘要 随着现代电子技术的快速发展,数据采集被应用于各行各业,并且在雷达测控以及医疗成像等领域需要采样率达到Gsps级别.为了提高实时信号采集的速度与准确性,在考虑到实时性与通用性情况下,设计一种具有FMC接口、5 Gsps采样率、10位分辨率的数据采集系统.该系统利用Kintex-7系列芯片作为核心芯片,控制E2V公司的高速ADC芯片EV10AQ190,采集的数据经过多相滤波算法,通过PCIe总线传输至上位机.文中对数据采集系统的方案设计进行了阐述,对数据采集系统进行验证,并与Matlab仿真进行对比,结果显示该系统可以达到数据采集系统的设计要求. With the rapid development of modern electronic technology,data acquisition is applied in all walks of life,and in radar measurement and control,medical imaging and other fields,the sampling rate is up to Gsps.In order to improve the speed and accuracy of real-time signal acquisition,a data acquisition system with FMC interface,5 Gsps sampling rate and 10 bit resolution was designed in consideration of real-time and generality.The system used the kintex-7 series chip as the core chip and controls the high-speed ADC chip EV10AQ190 of E2V company.The collected data was transmitted to the upper computer through the PCIe bus through the polyphase filtering algorithm.In this paper,the scheme design of the data acquisition system was described,the data acquisition system was verified and compared with the Matlab simulation.The results show that the system can meet the design requirements of the data acquisition system.
