摘要
为更快的进行AR放大器的维修,对维修方法进行了梳理。把故障分为3大类：1）放大器报错,2）放大器不工作,3）放大器达不到额定功率。放大器报错,可以根据报错指示灯来快速定位故障位置;放大器不工作,如果不能进入STANDBY状态,重点检查电源A,如果能进入STANDBY状态,检查电源B或者放大模块;放大器达不到额定功率,主要检查各放大电路,在检查放大模块时,为了节约时间,给出了用网络分析仪测驻波的方法。熟悉了这3种类型的故障,就能在AR放大器出现故障时迅速进行维修。
For AR amplifier faster maintenance,the maintenance methods are combed.Divide the faults into three broad categories.The first is amplifier reports a fault,and the second is the amplifier does not work,and third is the amplifier not up to the rated power.Amplifier reports a fault,according to the error indicator light to quickly locate the fault location.The amplifier does not work,if you can＇t enter the STANDBY state,focus on checking the power A;if you can enter the STANDBY state,check the power B or AMP module.The amplifier not up to the rated power,mainly check the amplification circuit.In order to save time when checking the AMP module,this paper presents a method of measuring the VSWR with a network analyzer.Familiar with these three types of faults,you can quickly repair the AR amplifier in the event of a failure.
