The principle of operation for the active hydrogen maser is based upon a 5 MHz quartz crystal oscillator, phase locked to the hyperfine transition of the hydrogen atom. The atomic hydrogen signal generated within the physics package is then picked up by an antenna in the cavity and coupled to the synchronization unit, which synchronizes the 5 MHz crystal oscillator signal phase to the hydrogen signal phase producing the 5 MHz and 100 MHz spectrally pure sine-wave signal output. 2, record 4, English, - active%20hydrogen%20maser
