电视发射机作为一种无线电设备,其经历了不同的发展阶段,目前电视发射机总的发展趋势是向全固态的方向发展。电视发射机利用电视激励器配置,可以自动进行切换,其本身具有预校正功能、载频偏置、精密偏置、控制半功率输出、遥控遥测接等功能,同时还具有优质的电源来进行并联发电。本文对电视发射机的使用、故障、维修和检测等进行了分析,并对电视发射机房的安全措施进行了说明,同时对我国数字电视发射机的发展趋势进行了具体的阐述。
As a kind of radio equipment, television transmitters have gone through different stages of development. At present, the general development trend of television transmitters is towards all-solid state. TV transmitter with TV actuator configuration, you can automatically switch, which itself has a pre-correction function, carrier frequency offset, precision bias, control half power output, remote telemetry and other functions, but also has high-quality power supply for parallel Power generation. This paper analyzes the use, fault, repair and detection of TV transmitters, and describes the security measures of TV transmitter room. At the same time, it also elaborates the development trend of digital TV transmitters in our country.
