4G耦合工具使用说明

1、MTK耦合工具使用说明本工具是基于MTK产线工具ATE针对NSFT （非信令综测）功能进行优化和简洁而 来的，手机与仪器的连接由传导改为耦合的方式，MTK内部叫作 Wireless NSFT.一、准备工作1.1用天线厂确认过性能的金机测试耦合环境的线损；手机通过耦合板连接仪器，在耦合板上找到最佳的位置，并记录各频段的线损。2.2将线损导入到配置文件（CFG）中;LTE频段的线损统一在LTE Cable Atte nuatio n目录下进行设置:LTE Cable AttenuationPort number = 2Portecablelossnumber = 13PortElcableloss
