6、TS COEDRI 73 & DRI 78及其产生机理及其产生机理 DRI 78 发射天线驻波比过高：DUP内置电路检测7/16”射频头处的发射/反射功率，没有信号发射时不检测，接收天线不检测。过高的VSWR将导致小区覆盖半径缩小、掉话率过高。 DRI 73 反射功率过高：发射通路发生严重故障将导致此告警。过长时间的高反射将不可避免地损坏CTU，所以它的检测周期比DRI 78短。告警产生几秒钟后CTU 将自动复位，所以处理故障时需要适当降低输出功率。BTSCOE CHINA 15 November 2004MOTOROLA CONFIDENTIAL PROPRIETARY, , Rev Num
