AI Article Synopsis
- The study characterizes three cryogenic sapphire oscillators (CSOs) using a straightforward method called the three-cornered-hat method, which is accessible with common tools.
- This method is effective in analyzing the fractional frequency stability limits of these advanced oscillators.
- The top-performing oscillator achieved a fractional frequency stability of better than 5 ×10^(-16) at 1 second and under 2 ×10^(-16) for longer durations.
Article Abstract
We present the characterization of three cryogenic sapphire oscillators (CSOs) using the three-cornered-hat method. Easily implemented with commercial components and instruments, this method reveals itself very useful to analyze the fractional frequency stability limitations of these state-of-the-art ultrastable oscillators. The best unit presents a fractional frequency stability better than 5 ×10(-16) at 1 s and below 2 ×10(-16) for [Formula: see text].
