Distributed amplified ultra-stable signal quartz oscillator based

International audienceThe aim of this communication is to present the performances of 5 MHz distributed ultra-stable system, based on ultra-stable Boitiers à Vieillissement Amélioré (BVA) oscillator. We demonstrated flicker frequency modulation (FFM) floor better than 4.5 × 10−14 ± 2.5 × 10−15 at 12 s with an intrinsic noise floor about 6 × 10−15 at 1 s with a τ−1/2 time integration dependence slope
