Hi Michael; So what I did with one of my 8607's was placed it in a cast aluminum box with 1/2 of soft silicon foam (it will never break down over time and heat) on all sides to provide not only mechanical isolation but thermal isolation as well. I actually did a bit more then that and would be glad to send you photos directly if interested. With an oscillator like the 8607 I think it is worth the effort. Stay Safe;

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.
