A Digital Servo System for Rubidium Frequency Standards
铷原子频标数字伺服系统

Principles of synchronous phase detecting and digital servo for rubidium atomic frequency standards(RAFS) were discussed.A digital servo system for rubidium frequency standards was designed with microcontroller unit,ADC and DAC.Frequency locking of a RAFS using the servo system was realized.The resulting frequency stability reached the level of common commercial RAFS.
