摘要
青台—南阳段微波通信电路传输电平较低,造成误码告警,严重时通信传输中断。为此,采用微波电测仪进行了现场测试分析,确认青台和南阳微波天线增益严重不足、青台馈线衰耗偏大是造成传输电平低的主要原因。青台和南阳的天馈线更换以后,传输电平恢复正常。
Because of low signal transmission level,error alarms and even breakdowns of transmission often occur at Qingtai—Nanyang microwave communication link.Analysis on the test results done by XPT-5/XPS-5 microwave electrical tester shows that the lack of antenna gain at both Qingtai and Nanyang,and bigger feeder lose in Qingtai are the main reasons.After the replacement of antenna and feeder at both sites,the transmission level returns to normal.
