产品概述

USRP N321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 ResearchRF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*无线研究课题提供了一个途径。同时N321提供TX/RX的LOs导出，提供给星型配置中多个其他的N320和N321。

USRP N321利用UHD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)的功能。

Trusted Platform Module (TPM)

可信平台模块

USRP N321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 N321有两种变体:

带TPM标准型(PN 786504-01)

非TPM型(PN 786919-01)

在中国大陆和香港只有USRP N321的非TPM型提供。N321带TPM型在法国、以色列或俄罗斯不可用，直到N321在这些国家被注册。
