I'm changing the topic from best rubidium frequency standard for this post.
Most repairs I make to the 5065A run well below $250.00, sometimes as low as $100.00. A "crazy bad" repair might run $400.00 or so but out of over 50 repairs only two needed that level of help. As far a tempco goes, unless your lab swings tens of degrees will you really see it? Short term stability scales with cell size and is also proportional to the design temperature. Also separate filter and resonance cells perform better than an "integrated" cell. The 5065A cell is the largest available today and the 66 degree C is the lowest temp around these days. The 5065A cell also has a temperature regulated stem to stabilize the Rubidium level. These combine to give a typical STS of 1.5X10-13 at a Tau of 100 Seconds. Unfortunately as others have noted, it is easily the most expensive Rubidium standard out there. A few members are looking into improving the tempco and I hope testing the barometric pressure performance.
