Abstract
Methods and apparatus for rapidly and automatically syntonizing the frequency of a passive atomic resonator of an atomic clock with a reference frequency which corresponds to the frequency of an external reference signal. Any difference between the hyperfine transition frequency of the resonator and the reference frequency generates an error signal which is used as a basis for automatically determining the magnitude of a quantity which adjusts the actual hyperfine transition frequency of the resonator.
