A Cryogenic Sapphire Resonator Oscillator with 1e-16 mid-term fractional frequency stability
Christophe Fluhr, Benoit Dubois, Claudio E. Calosso +3
We report in this letter the outstanding frequency stability performances of an autonomous cryogenique sapphire oscillator presenting a flicker frequency noise floor below 2e-16 ne…
Reliability and Reproducibility of the Cryogenic Sapphire Oscillator Technology
Christophe Fluhr, Benoît Dubois, Guillaume Le Tetu +4
The cryogenic sapphire oscillator (CSO) is a highly specialized machine, which delivers a reference signal exhibiting the lowest frequency fluctuations. For the best units, the All…
Magnetic sensitivity of the Microwave Cryogenic Sapphire Oscillator
Vincent Giordano, Christophe Fluhr, Benoit Dubois
The Cryogenic Sapphire Oscillator is today recognized for its unprecedented frequency stability, mainly coming from the exceptional physical properties of its resonator made in a h…
KLTS: A rigorous method to compute the confidence intervals for the Three-Cornered Hat and for Groslambert Covariance
Éric Lantz, Claudio E. Calosso, Enrico Rubiola +4
The three-cornered hat / Groslambert Covariance methods are widely used to estimate the stability of each individual clock in a set of three, but no method gives reliable confidenc…
Frequency Stability Measurement of Cryogenic Sapphire Oscillators with a Multichannel Tracking DDS and the Two-Sample Covariance
Claudio E. Calosso, François Vernotte, Vincent Giordano +2
This article shows the first measurement of three 100 MHz signals exhibiting fluctuations from 2E-16 to parts in 1E-15 for integration time tau between 1 s and 1 day. Such stable s…
Cross-Spectrum PM Noise Measurements, Thermal Energy and Metamaterial Filters
Yannick Gruson, Vincent Giordano, Ulrich L. Rohde +2
Virtually all commercial instruments for the measurement of the oscillator PM noise make use of the Cross Spectrum method (arXiv:1004.5539 [physics.ins-det], 2010). High sensitivit…
