产品概述

USRP N320是一个网络型SDR设备,为大规模和分布式无线系统的部署提供可靠性和容错能力。这是一款高性能SDR,采用Ettus Research独特RF设计,半宽RU大小,提供2个TX/RX通道。每个通道提供高达200Mhz的瞬时频宽,频率覆盖3MHz~6GHz。基带处理使用Xilinx Zynq-7100 SoC来提供大容量用户可编程FPGA,用于实时、低延迟处理;以及一个双核ARM CPU用于独立运行。支持1GigE、10GigE和Aurora接口,支持2个SPF+端口和1个QSFP+端口,支持主机PC或FPGA协处理器的高吞吐量IQ流。


灵活的同步架构,支持10MHz、1PPS参考,外部TX/RX LO输入,和GPSDO实现相位一致MIMO试验平。通过引入任何超过450 MHz的TX/RX LOs, USRP N320为建立大型、相位一致的MIMO测试平台等一系列先进无线研究课题提供了一个途径。


USRP N320利用UHD最新的软件开发,简化了对网络上多个设备的控制和管理,具有远程管理任务(如调试、更新软件、重新启动、重新设置到工厂状态和监视系统健康状况)的独特功能。

可信平台模块Trusted Platform Module (TPM)

USRP N320包括一个可信平台模块,以支持一些安全特性,比如文件加密。由于产品在一些国家的产品适用性限制,对带有TPM(可信平台模块)组件的产品,USRP N320有两种变体:

         带TPM标准型(PN786503-01)

         非TPM型(PN786918-01)

在中国大陆和香港只有USRP N320的非TPM型提供。N320 带TPM型在法国、以色列或俄罗斯不可用,直到N320在这些国家被注册。
