USRP E312

内置电池的USRP E312提供了一个便携式自主运行的软件定义的无线电平台，设计用于现场部署。来自Analog Devices的灵活的2×2 MIMO AD9361收发器提供高达56MHz的瞬时带宽，频率范围覆盖70MHz～6GHz，覆盖多个感兴趣的波段。发射机和接收机前端的射频滤波器组都提高了选择性。

基带处理器使用Xilinx Zynq 7020 SoC来提供FPGA加速计算，并结合双核ARM CPU支持的独立操作。USRP E312包括一套丰富的外围设备，如用于位置感知和时间同步的集成GPS接收器，以及用于扩展存储、I/O和与现有设备通信的两个主机USB端口。用户可以快速原型化和部署具有紧凑的大小、重量和功率需求的移动和嵌入式应用程序的设计。

USRP嵌入式系列平台使用OpenEmbedded框架创建定制的Linux发行版，以满足应用程序的特定需求。默认的操作系统预先安装了UHD软件API和各种第三方开发工具，如GNU Radio。对RFNoC FPGA开发框架的支持使实时和宽带信号处理的确定性计算成为可能。
