摘　　要：该文以典型USRP设备X310为例,先对USRP零中频采样架构在射频测试中可能带来的问题进行了理论分析,并通过实际测试对理论分析结果进行了验证。结合RSU信道分配及视频传输的需求,证实了USRP对RSU进行功能测试和仿真的有效性,并对实际测试中可能产生的问题进行了分析,并给出建议,能够为USRP在相关领域中的应用提供借鉴。Taking the typical USRP equipment x310 as an example,this paper makes a theoretical analysis on the possible problems of USRP's zero IF sampling architecture in RF test.And related tests are performed to verify the analytic results.Based on the test requirements of RSU's channel allocation and video transmission,this paper confirms the effectiveness of USRP's functional test and simulation on RSU,analyzes the possible causes of defects and gives some suggestions,which can benefit to the application of USRP in related fields.
