Microwave synthesis for the PTB caesium fountain clocks
IEEE Transactions on Instrumentation and Measurement(2020)
摘要
Microwave synthesizers that are used to generate microwave signals for the CSF1 and CSF2 fountain clocks at the Physikalisch-Technische Bundesanstalt (PTB) are described. The synthesizers are based on a divider chain and a digital frequency synthesis and have been designed for use with an optically stabilized microwave oscillator. They have been designed in a modular fashion to assure long-term op...
