[time-nuts] Question for the cesium nuts.

Much more common. We're talking tens of thousands of these manufactured
against a few hundred Caesium (Cesium) standards, and a handful of MASERS in
a year, so priced accordingly.

Just looked at the item on EBay. This is the "physics package" from a Rb
standard including the Rb cell. It would need the electronics, oscillator
and PSU wrapping round it to become a Rb standard.

Try Item Number 290093161408 for a complete unit.

Kind Regards

What about rubidium standards? Are they more common due to lower price?

Speaking of which, Ebay has several "Rubidium atomic clock smallest cell
frequency standard" listed for US$20. What are these modules?
