A Scheme for Generating Discontinuous Microwave Inquiry Signal in Rubidium Atomic Frequency Standard
Publikováno v:
Chinese Journal of Magnetic Resonance, Vol 37, Iss 02, Pp 209-215 (2020)
The microwave probing signal of the rubidium atomic frequency standard (RAFS) is used to excite the transitions between the ground-state energy levels of rubidium atoms, and realize resonance detection. At present, the microwave generation schemes co
