What is an Atomic clock ?
Atomic resonance is intrinsically more stable than quartz local oscillator.
“Natural” atomic microwave resonance frequency is synthesized from RF LO.
Control Loop continuously steers LO frequency to atomic resonance.
RF output (10 MHz) embodies stability of atomic resonance.
