“711”雷达接收机包括信号放大部分和频率调整部分。从线路上看,基本上是五十年代军用雷达接收机的典型线路,因此,性能比较稳定。如果正确使用,此部分基本上很少出现故障。但是出现故障时,较难排除,调整也比较复杂。 本文对接收机常出现的故障加以分析,对如何调整的问题谈点看法。 一、接收机信号放大部分 The “711” radar receiver includes a signal amplification section and a frequency adjustment section. From the point of view of the line, it is basically a typical line of a military radar receiver in the fifties. Therefore, the performance is relatively stable. If used correctly, there are few problems with this section. However, when a fault occurs, it is difficult to eliminate and adjust more complicated. This article analyzes the frequently occurring faults in the receiver and talks about how to adjust the problem. First, the receiver signal amplification part
