6、TS COEDRI 73 & DRI 78及其產生機理及其產生機理 DRI 78 發(fā)射天線駐波比過高：DUP內置電路檢測7/16”射頻頭處的發(fā)射/反射功率，沒有信號發(fā)射時不檢測，接收天線不檢測。過高的VSWR將導致小區(qū)覆蓋半徑縮小、掉話率過高。 DRI 73 反射功率過高：發(fā)射通路發(fā)生嚴重故障將導致此告警。過長時間的高反射將不可避免地損壞CTU，所以它的檢測周期比DRI 78短。告警產生幾秒鐘后CTU 將自動復位，所以處理故障時需要適當降低輸出功率。BTSCOE CHINA 15 November 2004MOTOROLA CONFIDENTIAL PROPRIETARY, , Rev Num
