[time-nuts] LPRO Pressure Sensitivity

[Bob Camp]

Hi

Yes indeed. 

There really isn't a lot of data out there on pressure on rubidiums. Of course we don't talk about it a lot on our data sheets either ...

If you accept that a normal day might have a 100 millibar change,  That changes the frequency 10 ppt, if the guess is right. At 10X that level it would be as significant as temperature on a good unit. If it was that big it should get a lot more attention ...
