BTS Master MT8220T 是安立公司的第三代高性能手持基站分析仪，此分析仪经过特别开发升级，现在不仅支持 2G、3G 和 WiMAX 网络，还支持 4G 无线网络。 MT8220T 为 LTE eNodeB 测试提供 20 MHz 解调带宽，并配备了高对比度的触屏显示屏和背光键盘，可在强自然光和阴暗的环境下使用。
资深无线技术员和射频工程师们借助 BTS Master MT8220T 基站分析仪，能够对基站的安装和运行情况执行精确、快速的验证，从而实现最佳无线网络性能并确保对其进行持续维护和故障排除，以便保持您的无线网络基础设施以最佳状态正常运转。标配的3年质保表明该仪表具有世界级的可靠性，并可使客户安心拥有并使用MT822OT BTS Master。
2G、3G 和 4G 网络信号分析仪能够测试无线信号的射频质量和调制品质，进而可对基站发射器中几乎所有子系统的性能进行验证。 每类信号分析选项均具有的下行空口(OTA)测试功能，可帮助现场工程师可测试难以访问的远程射频头端 (RRH) 等信号发射器的性能并解决解决覆盖问题，检查 LTE 和 TD-LTE 的 MIMO 调制是否正确运行。CPRI射频测试选件允许用户通过方便的接入光纤链路来检查上行干扰问题。
The new, patented PIM over CPRI option is a non-intrusive method of measuring passive intermodulation (PIM) using live traffic over the Common Public Radio Interface (CPRI) link. It is set to change the dynamics of PIM detection by enabling users to test at ground level, any time of the day – with no site turn down required. By tapping into the CPRI data on the downlink and uplink between the remote radio head and baseband unit, the BTS Master MT8220T can calculate the PIM desensitization of the LTE uplink. In addition, the PIM over CPRI measurement option will also determine if the PIM found is internal or external to the antenna system, which is useful in deciding whether a tower crew needs to be call on site.
BTS Master MT8220T 体积小、重量轻且用电池供电，这些优点帮助技术人员在任何基站测试现场均可轻松地展开工作。 该仪器开机预热时间不到 5 分钟，既能节省电池电量，又能使您快速地开始测量工作。 GPS接收机是该仪表的标准特色，与安立公司的干扰捕获方案想结合，可以很方便的对各类干扰信号进行地图显示和三角定位。
对于某些关键性能指标 (KPI) — 例如因单元基站故障或干扰引起的呼叫中断、呼叫拒绝或呼叫阻塞率 — 您可借助 BTS Master MT8220T 这种集多功能于一体的设备快速解决遇到的所有问题。 对于网络运营商、分包商和安装人员来说，这是唯一一款完全集成的、触摸屏的手持设备，该设备将传输线扫描、具备MIMO测试功能的总和信号分析、超灵敏的频谱分析和复杂干扰信号的跟踪等功能集成到一个紧凑且便于使用的设备当中。
