The NPL has developed a miniaturised Atomic Fountain Clock that promises to make accurate timekeeping technology smaller.

The XLi Grandmaster Clock with GPS reference is the first test and measurement solution to help users verify the performance of IEEE 1588 products in their networks, according to Symmetricom Inc. The ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference ...

This video is part of Microwaves & RF's IMS 2023 coverage. The video transcript below has been edited for clarity. Today, we have a nice demo of the world's lowest-power atomic clock, the chip-scale ...

"This book provides a introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic frequency standards, ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...

Jitter remains one of the most important specifications when measuring the goodness of a device. Compliance packages specify random jitter, deterministic jitter, time interval error, and total jitter.

To measure time, you need a constant rhythm. For eons, the regular movements of the sun and moon have set the pace for all of life on Earth. But over millennia, humans have sought and found more ...
