軟件無線電USRP N320產(chǎn)品概述

USRP N320是一個(gè)網(wǎng)絡(luò)型SDR設(shè)備，為大規(guī)模和分布式無線系統(tǒng)的部署提供可靠性和容錯(cuò)能力。這是一款高性能SDR，采用Ettus Research獨(dú)特RF設(shè)計(jì)，半寬RU大小，提供2個(gè)TX/RX通道。每個(gè)通道提供高達(dá)200Mhz的瞬時(shí)頻寬，頻率覆蓋3MHz~6GHz。基帶處理使用Xilinx Zynq-7100 SoC來提供大容量用戶可編程FPGA，用于實(shí)時(shí)、低延遲處理；以及一個(gè)雙核ARM CPU用于獨(dú)立運(yùn)行。支持1GigE、10GigE和Aurora接口，支持2個(gè)SPF+端口和1個(gè)QSFP+端口，支持主機(jī)PC或FPGA協(xié)處理器的高吞吐量IQ流。

靈活的同步架構(gòu)，支持10MHz、1PPS參考，外部TX/RX LO輸入，和GPSDO實(shí)現(xiàn)相位一致MIMO試驗(yàn)平。通過引入任何超過450 MHz的TX/RX LOs, USRP N320為建立大型、相位一致的MIMO測(cè)試平臺(tái)等一系列先進(jìn)無線研究課題提供了一個(gè)途徑。

USRP N320利用UHD最新的軟件開發(fā)，簡(jiǎn)化了對(duì)網(wǎng)絡(luò)上多個(gè)設(shè)備的控制和管理，具有遠(yuǎn)程管理任務(wù)(如調(diào)試、更新軟件、重新啟動(dòng)、重新設(shè)置到工廠狀態(tài)和監(jiān)視系統(tǒng)健康狀況)的獨(dú)特功能。

可信平臺(tái)模塊Trusted Platform Module (TPM)

USRP N320包括一個(gè)可信平臺(tái)模塊，以支持一些安全特性，比如文件加密。由于產(chǎn)品在一些國家的產(chǎn)品適用性限制，對(duì)帶有TPM(可信平臺(tái)模塊)組件的產(chǎn)品，USRP N320有兩種變體:

         帶TPM標(biāo)準(zhǔn)型(PN786503-01)

         非TPM型(PN786918-01)

在中國大陸和香港只有USRP N320的非TPM型提供。N320 帶TPM型在法國、以色列或俄羅斯不可用，直到N320在這些國家被注冊(cè)。
