一种基于FPGA的1Gsps数据采集卡设计

摘要

针对现代电子侦查对抗技术要求能够对超宽频率范围的环境信号进行快速截获和分析,文章提出了一种以FPGA作为主控制器的超宽带1Gsps高速数据采集卡设计方案,详细地阐述了硬件平台的架构.并通过QUARTUS 8.0软件内部的嵌入式逻辑分析仪(SignalTap ii)来捕获采集到的数据.通过对测试结果的分析表明,该数据采集卡能准确还原被采样的模拟信号,满足设计要求.%Aiming at modem electronic investigation against technology require rapid intercept and analysis environmental signal in a super wide frequency range, this paper puts forward a design of lGsps data acquisition card that based on FPGA, expounds the hardware platform in detail. Using the Embedded logic analyzer(SignatTap ii)in QUARTUS 8. 0 software to capture the data. Through the analysis of test result, shows that the data acquisition card can accurately reduction the sampling analog signal and the circuit meets the design requirement
