Hi Hans,
how many, what options, and what price? Are they NOS? Tested?
thanks,

Hi Hans --
I'd be interested in one. What's the specific model number, and the price?
Thanks,
John

Yep!!!
I'm also interested in one of those oscillators... A
quartz that rivals Rb is surely a good shot!
So, price and availibility please...

Is anyone else surprised that they're using an AT cut rock rather than an SC?

Hans,
I am also interested in one or more of these. The response seems like
it will overwhelm the number of units you may have available.

Yes, I was surprised. They also use a double

The PDF says that nothing contacts the crystal, which implies capacitive

Oscilloquartz is part of the Swatch group. It has been in the business of
time synchronization for more than 20 years. All that I could learn from
their web site is that they are proud of their BVA
From what I have read, BVA technology is about as good as it gets for the best
close-in phase noise in a quartz crystal. It was once desribed to me as
having the lowest quartz-to-crud-ratio since the elctrodes are not plated on
to the quartz. A limiting factor can be that less RF power can be
BVAs certainly are the crème de la crème of OCXOs. I have seen examples that
have been running for several years that exhibit aging down to a few parts
in E-12 per day!!
The Father of the BVA was Raymond Besson, who now works for Laboratoire
de Chronométrie Electronique Piézoélectricité,

If you look closely you will find that the BVAs exists in both AT and SC cut

Yes, but isn't the SC cut rock only in the 8607?

Dear Gentlemen
Many thanks for your great interest and the many bids on the OSA 8600 BVA
oscillators. Few minutes ago I made the decision and sold the three units.
It seems that some of you are aware of the BVA resonator

compute Allan deviation. There are quite a few that

By the way -- it builds just fine under Linux without any changes.
gcc -lm -o adev1 adev1.c
will yield an executable, with one warning because main() doesn't return
an int.
