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 Rob Kimberley -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Keith E.

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? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ LtCol Keith E.
