GM338电台在VE432可控震源上的应用

摘要

VE432可控震源控制系统原配电台为GM300，因使用环境恶劣、使用年限长，电台性能下降，故障率上升。因此，决定用性能稳定、抗振动、耐高温的同系列的新型电台GM338代替GM300。但GM338电台直接代替GM300电台与VE432可控震源控制系统匹配使用，必须进行相应的改进。本文详细地分析了GM338电台的电路特点，介绍了具体的改进方法。%The original radio type for VE432 control system is GM300. The poor conditions and long service life resulted in increasing failure rates. Another new type radio, GM338 with stable performance and anti-vibration function as well as high working temperature, is often adopted to replace GM300. To match with VE432 well, some transfor- mation should be done to GM338 and GM300. This paper analyzes the circuit characteristics of GM338 radio and in- troduces the detailed method for transformation.
