Abstract: High-precision Frequency Standard Comparator is a kind of instrument to measure frequency stability. It adopts the means of time interval difference and multiple frequency difference. Test results show that its actual frequency stability can be as high as 5.0E-14/1s.

Key words: Atom frequency standard, Compare, Frequency stability
