Tender description

This requirement is for the supply of caesium beam tube atomic clocks, quantity 4. the items must be units that are recognised as international precision frequency standards, suitable for Universal Coordinate Time (UTC) generation and matching the majority of clocks contributing to the BIPM database. Four cesium beam tube atomic clocks with including the following characteristics: — meantime between failure of 160 000 hours or more, — full traceability to NIST for accuracy measurements, — +/- 5x10^-13 full-environment fractional frequency accuracy, — flicker floor of 1,0 x 10^ — 14 or better, — fractional frequency stability of 5 x 10^ — 12 or better at 1 second, — output signals of 10 MHz, 5MHz and 1 PPS.
