[time-nuts] Cheap Rubidiums

[Corby Dawson]

Bob,

Sounds like a good thing to try.

It just depends how many DOXCOs you have to go thru to find one that
gives you a decent short term stability in the 1 to 100 second range.

I have found that even if the published spec is 1X10-12th at 1 thru 100
seconds actually finding units that perform that well is problematic!

The venerable HP 10811 series usually exceeds its spec. by a good amount!


I use a "cherry picked" 10811-60111 that runs at 5X10-13th from 1 to 100
seconds!

Had to test a whole pile to find such a overachiever!

See my post jan 2009 "More quartz short term stabilities"

You might also consider using temperature measuring system tied to the
baseplate and drive the C-field to cancel frequency changes due to
temperature.

Could be simpler than designing and operating some sort of oven system.
