The laboratory is equipped with two Cs Clocks of HP/Agilent 5071A Primary Frequency Standard.  The clocks are configured as an ensemble, installed in fully conditioned room. A back-up dc supply is provided to ensure their continuous running.



Cs Clock is the phisycal realization of SI second definition as accepted by CGPM since 1967






In the future, the laboratory propose to increase the number of Atomic Clocks, including Passive Hydrogen Maser Clock to increase the stability of the time scale realization in short term as well as in long term.
