Michael,
These are really good oscillators so in addition to guessing what sounds
like a good solution verify with actual vibration / acceleration
experiments.
Last year I tested some Oscilloquartz BVA's for axis sensitivity to
acceleration. It's quite easy. Some plots here:
http://leapsecond.com/pages/bva-rotate/
At the end of that page are two videos showing the Arduino-driven
stepper motor rotating platform that I used. If anyone can't view the
videos let me know off-list (my email is [email protected]).
If you end up doing something similar I would very much like to see how
your results compare.
Thanks,

I have three Oscilloquartz 8607-Bs that I'm rehousing.
In their former life they were part of the frequency synthesis chains
for H-masers and they hung vertically from a rubber suspension that was
presumably intended to provide vibration isolation. Unfortunately, the
person responsible for this has long since retired so is no longer
around to ask questions of.
In the experiment I will be averaging over 100 s, which suggests to
me that very low frequencies are what I need to filter out (if at
all), and I am skeptical that the rubber will do this. Space is tight
so I am wondering
whether I should simply ditch the isolation.
What do other people do with their quartzes ? I thought I should ask
for some advice before attempting measurements.
Cheers
Michael
