[Paul] likes a precise oscillator. His recent video shows a crystal oscillator with a “watch crystal” and a CMOS counter, the CD4060. Using such a circuit can produce very stable frequencies ...

[W3AXL] picked up a rubidium reference oscillator on eBay at a low cost, and he shows us how it works in the video you can see below. He started with a GPS-disciplined oscillator he had built ...

In the early 1980s, researchers at NASA's Jet Propulsion Laboratory in California realized that stable reference signals ... the realization of a microwave oscillator based on RF photonics.

Oven-controlled crystal oscillators are used as a reference signal source in such applications because of their high stability. The crystal oscillator is enclosed in a temperature-controlled ...
