Lowest flicker-frequency floor measured on BVA oscillators

In this paper we will present the results of the time-domain measurement of short-term frequency stability on 7 ultra-stable 5-MHz Boitier a Vieillissement Ameliore (BVA, improved aging case) oscillators. The measurements took place in the Institute of Photonics and Electronics (IPE) in July 2008 and was a continuation of the stability measurements of BVA oscillators reported in our previous work.
