电视发射机是全固态单通道电视发射机,采用专业级电视激励器,可单双激励器配置,自动切换。他本身具有多种线性、非线性预校正功能、载频偏置、精密偏置(配合外高精度基准源)功能,可预制和可控制半功率输出,并具有遥控遥测接口。功放采用进口LDMOS场效应管,模数兼容,并采用优质的开关电源并联供电。笔者针对电视发射机的维护和管理进行分析和阐述。
TV transmitter is an all-solid-state single-channel TV transmitter, a professional-level TV actuator, single and double exciter configuration, automatic switching. He has a variety of linear, non-linear pre-correction function, carrier frequency offset, precision offset (with high precision reference source) function, prefabricated and controllable half power output, and with remote telemetry interface. Power amplifier imported LDMOS FET, modulus compatible, and the use of high-quality switching power supply in parallel. The author analyzes and expounds the maintenance and management of TV transmitters.
