由于抗干扰的需要,广电总局给全国的卫星地球站配备了GIN Ⅳ新一代速调管功率放大器。GEN Ⅳ速调管高功放采用了多收集极速调管(MSDC)作为末级功率放大,采用分布式的微处理系统,CAN内部总线,便于远程监控。在各站投入工作以来,工作稳定,全国各站遇到的故障常见有软件设置或者通讯监控方面的,而对于高功放硬件故障的检修记录还不多见。 Due to the need of anti-jamming, SARFT has equipped the satellite earth stations in the country with a new generation of GIN IV klystron power amplifiers. GEN IV klystron high-power amplifier uses a multi-collection speed tube (MSDC) as the last power amplifier, using a distributed microprocessor system, CAN internal bus for easy remote monitoring. Since the station was put into work, the work has been stable. The faults encountered in all stations across the country are often related to software settings or communications monitoring. Records of overhauling of high-power hardware failures are rare yet.
