Fts 4060 Cesium Frequency Standard Leapsecond

Description. The FTS 4010 was designed to be a portable Cesium frequency standard and clock. True, it is battery operated, it has a handle on one side, rubber feet on the other, and even a 1970s style wooden enclosure complete with ventilation holes, but at 55 lbs I wouldnt want to carry it very far.

The cesium clocks are considered primary because of their degree of radiation hardness, their

Fts 4060 Cesium Frequency Standard

The measure of how the frequency changes with running time is called aging. The specification on the HP Agilent 5071A Cesium standard 50k is less than 1E-14 per day.. Thats to say that if it was set with a zero offset at noon today, by tomorrow noon it might by off frequency by 1E-14.

Hp 5060a Cesium Beam Frequency Standard

Cesium frequency standards work by squirting Cesium atoms from a reservoir thats heated to boil off some atoms from a small piece of cesium liquid metal. These atoms are processed is such a way that they become an atomic frequency standard.
