產(chǎn)品概述

USRP N310是一種網(wǎng)絡(luò)軟件定義無(wú)線電(SDR)，為大規(guī)模和分布式無(wú)線系統(tǒng)的部署提供可靠性和容錯(cuò)能力。USRP N310設(shè)備通過(guò)引入的功能來(lái)遠(yuǎn)程執(zhí)行任務(wù)，如更新軟件、重新啟動(dòng)、工廠重置、自我測(cè)試、主機(jī)PC/ARM調(diào)試和監(jiān)視系統(tǒng)健康狀況，從而簡(jiǎn)化了無(wú)線電網(wǎng)絡(luò)的控制和管理。

USRP N310是SDR市場(chǎng)中通道密度的設(shè)備之一，提供4個(gè)RX和4個(gè)TX通道，具有半寬RU尺寸。RF前端使用兩個(gè)AD9371收發(fā)器，這是來(lái)自Analog Device的RFIC技術(shù)。每個(gè)頻道提供高達(dá)100MHz的瞬時(shí)頻寬，頻率范圍涵蓋10MHz～6GHz。

開源的USRP硬件驅(qū)動(dòng)程序(UHD) API和射頻片上網(wǎng)絡(luò)(RFNoC) FPGA開發(fā)框架減少了軟件開發(fā)工作，并與GNU Radio等多種行業(yè)標(biāo)準(zhǔn)工具集成。用戶可以快速原型化和可靠地部署各種SDR應(yīng)用程序的設(shè)計(jì)，如無(wú)線試驗(yàn)臺(tái)、遠(yuǎn)程無(wú)線電頭、頻譜監(jiān)控等。請(qǐng)注意，USRP N310不是為快速調(diào)諧而設(shè)計(jì)，因而不適合跳頻應(yīng)用。

基帶處理器

基帶處理器使用Xilinx Zynq-7100 SoC來(lái)提供一個(gè)大容量用戶可編程FPGA，用于實(shí)時(shí)和低延遲處理，以及一個(gè)雙核ARM CPU用于獨(dú)立操作。用戶可以直接將應(yīng)用程序部署到預(yù)裝的嵌入式Linux操作系統(tǒng)上，或者通過(guò)兩個(gè)SFP+端口使用高速接口(如1GigE、10GigE和Aurora)將采樣數(shù)據(jù)注入到PC上。

同步

USRP N310具有靈活的同步體系結(jié)構(gòu)，支持傳統(tǒng)的SDR同步方法，如時(shí)鐘參考、PPS時(shí)間參考和GPSDO，從而實(shí)現(xiàn)了高通道數(shù)MIMO系統(tǒng)。此外，USRP N310采用開源的White Rabbit時(shí)序協(xié)議，具有的基于以太網(wǎng)的同步特性。在沒(méi)有g(shù)ps的環(huán)境中，White Rabiit可以實(shí)現(xiàn)長(zhǎng)距離的精確基帶同步。有關(guān)更多信息，請(qǐng)參考“Using Ethernet-Based Synchronization on the USRP N3xx Devices"。

可信平臺(tái)模塊(TPM)

USRP N310包括一個(gè)可信平臺(tái)模塊，以支持一些安全特性，如文件加密。由于產(chǎn)品在一些國(guó)家的適從性限制，USRP N310有兩種變體:

帶TPM標(biāo)準(zhǔn)型(PN 785067-01)

非TPM型(PN 786465-01)

在中國(guó)大陸和香港只有USRP N310的非TPM提供。USRP N310帶TPM型在法國(guó)、以色列或俄羅斯不可用，直到在這些國(guó)家注冊(cè)。

[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.
