摘　　要：目前移动通信领域中设备研发、网络建设、网络优化的测试装置大多只支持单一的网络制式,同时面临扫频速度不够高的问题,为运营商带来诸多不便。提出了一种新型多模高速扫频仪硬件架构,支持各种网络制式,同时采用多通道基带处理方式显著提高了扫频速度,增加打点数目,反映了网络覆盖细节,为网络性能测试、网络优化测试提供了可靠的分析数据。The fields of mobile communications equipment research and development, network construction, network optimization test devices mostly only support a single network standard, while facing the problems that the sweep speed is not high enough and it brings a lot of inconvenience to the oper- ators. This paper proposes a multi-mode,high-speed scanner hardware architecture which supports a variety of network standard and a multi-channel baseband processor which significantly increases the sweeping speed and increases dot numbers. And it reflects network coverage details, and provides a reliable analysis of data with the network performance and the network optimization test.
