A clock containing a quartz oscillator stabilized by a rubidium standard.

A frequency standard in which a specified hyperfine transition of electrons in rubidium-87 atoms is used to control the output frequency.
Note: A rubidium standard consists of a gas cell, which has an inherent long-term instability. This instability relegates the rubidium standard to its status as a secondary standard.
