摘要
全固态的PDM 1KW中波广播发射机对于系统电路在进行调制处理时,借助放大器件的固态组件予以实现,充分保证了发射中波信号的良好清晰程度。并且对于脉冲宽度在实施调整的过程中,运用全固态的广播发射装置有助于中波发射效率的提升以及发射信号时间的缩短,体现了全固态的PDM 1KW中波广播发射装置具备特殊的系统运行优势。在此前提下,技术人员针对全固态的中波广播发射机主要应当明确广播发射装置的基本运行特征,并且还要结合广播发射系统的常见运行故障情形来实施全面的系统维护与故障检测处理。
All-solid PDM 1KW medium wave broadcasting transmitter is realized by the solid components of amplifying devices when modulating the system circuit,which fully guarantees the good clarity of the transmitted medium wave signal.In addition,in the process of pulse width adjustment,the application of all-solid-state broadcast transmitter is helpful to improve the transmission efficiency of medium wave and shorten the time of transmitting signals,which shows that all-solid-state PDM 1KW medium wave broadcast transmitter has special advantages in system operation.On this premise,technicians should mainly clarify the basic operating characteristics of the broadcast transmitter for all-solid-state mediumwave broadcast transmitters,and implement comprehensive system maintenance and fault detection processing in combination with the common operating faults of the broadcast transmitter system.
