摘　　要：通信、雷达和高速数传等类似系统需要高稳定性、高质量的基准信号源作为日常信息的载波所传输信号的载体,载波信号的干净程度(频谱纯度)对通信质量有着直接的影响。数字频率合成技术是全固态中波发射机的核心技术之一,振荡器在中波发射台站有广泛的应用。基于此,介绍振荡器的原理和常见故障排除方法,以提升业务水平,实现安全优质播出。Communication, radar, high-speed data transmission and other similar systems need a reference signal source with high stability and quality as the carrier of the signal transmitted by the carrier of daily information. The cleanliness(spectral purity) of the carrier signal has a direct impact on the communication quality. Digital frequency synthesis technology is one of the core technologies of all solid state MW transmitter. Oscillators are widely used in MW transmitter stations. Based on this, this paper introduces the principle of the oscillator and common troubleshooting to improve the business level and achieve safe and high-quality broadcasting.
