We subjected super high-performance quartz oscillators (Super DOCXO) and rubidium atomic clocks to the exact same temperature conditions. Both devices were connected to the same GPS simulator using a GNSS splitter and both were powered at the same time, having been locked to GPS for 72 hours before holdover initiation.

Global Rubidium Atomic Clock Industry Trends and

Rubidium atomic clock or rubidium standard, is a high accuracy frequency and time standard. Rubidium atomic clocks, the simplest and most compact of other atomic clocks, use a glass cell of rubidium gas that changes its absorption of light at the optical rubidium frequency when the surrounding microwave frequency is just right.
