When analyzing the robustness of data transmission systems, jitter is a key indicator. It is recommended to use jitter measurement instruments for both the time and frequency domain in order to ...

Over the past 40 years, a number of discoveries in quantum physics have completely transformed our vision of fundamental metrology. This revolution starts with the frequency stabilization of lasers ...

In the past few years, optical atomic clocks have made spectacular progress, becoming 100 times more precise than the best caesium clocks. So far, their precision has been available only locally, ...
