产品概述

USRP N310是一种网络软件定义无线电(SDR)，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。USRP N310设备通过引入的功能来远程执行任务，如更新软件、重新启动、工厂重置、自我测试、主机PC/ARM调试和监视系统健康状况，从而简化了无线电网络的控制和管理。

USRP N310是SDR市场中通道密度的设备之一，提供4个RX和4个TX通道，具有半宽RU尺寸。RF前端使用两个AD9371收发器，这是来自Analog Device的RFIC技术。每个频道提供高达100MHz的瞬时频宽，频率范围涵盖10MHz～6GHz。

开源的USRP硬件驱动程序(UHD) API和射频片上网络(RFNoC) FPGA开发框架减少了软件开发工作，并与GNU Radio等多种行业标准工具集成。用户可以快速原型化和可靠地部署各种SDR应用程序的设计，如无线试验台、远程无线电头、频谱监控等。请注意，USRP N310不是为快速调谐而设计，因而不适合跳频应用。

基带处理器

基带处理器使用Xilinx Zynq-7100 SoC来提供一个大容量用户可编程FPGA，用于实时和低延迟处理，以及一个双核ARM CPU用于独立操作。用户可以直接将应用程序部署到预装的嵌入式Linux操作系统上，或者通过两个SFP+端口使用高速接口(如1GigE、10GigE和Aurora)将采样数据注入到PC上。

同步

USRP N310具有灵活的同步体系结构，支持传统的SDR同步方法，如时钟参考、PPS时间参考和GPSDO，从而实现了高通道数MIMO系统。此外，USRP N310采用开源的White Rabbit时序协议，具有的基于以太网的同步特性。在没有gps的环境中，White Rabiit可以实现长距离的精确基带同步。有关更多信息，请参考“Using Ethernet-Based Synchronization on the USRP N3xx Devices"。

可信平台模块(TPM)

USRP N310包括一个可信平台模块，以支持一些安全特性，如文件加密。由于产品在一些国家的适从性限制，USRP N310有两种变体:

带TPM标准型(PN 785067-01)

非TPM型(PN 786465-01)

在中国大陆和香港只有USRP N310的非TPM提供。USRP N310带TPM型在法国、以色列或俄罗斯不可用，直到在这些国家注册。

[1] The RF front-end uses two AD9371 transceivers that are independently tunable. Each transceiver is capable of 2X2 MIMO operation with LO sharing between each channel.

[2] The RJ45 port is used for remote management of the device and does not support IQ streaming.

[3] The external LO frequency must be twice the center frequency, with center frequency limited to the range from 300 MHz to 4 GHz. Phase coherency is not repeatable after retune or reinitialization of the RF front-end. Phase recalibration is required after these operations.
