Oh fudgknockers.... I could have sworn I saw RB models with the GPS antenna inputs, but looking at the few pictures I can find, I think you are right. Please don't burn me at the stake, at least not until after Christmas.
I sincerely apologize, I honestly thought they had the antenna input, but I guess it was the RFTG XO that has it, and the RB ties into it. For the $130 BIN (before the raised the price), it seemed like a great deal even just for the Rb unit. It has a 1PPS label on the front, I do not know if it is an input or output. I'm going to cross my fingers and hope it is an input. The RB unit itself is a "special" FE-5680A and the life is 20 years. (That is what the FEI guy said.) I know these Lucent modules were made for mobile / temporary / emergency cell sites, so they probably have not had much use. http://www.freqelec.com/pdf/12pager.pdf http://www.gillam-fei.be/products/pdf/others/rubidium/FEI%20-%205680A.pdf I did also see this on eBay a while back, but I think the DDS is a special option. Still good info to have on hand just incase: eBay Item number: 160048938286 - $960 eBay Item number: 160062108623 - $515 Jason (Don't Kill Me) Rabel > I think you just steered me down a blind alley... > > I grabbed the last two of these at the newer higher price of > $185 BIN but more careful searching shows photos of a box without any > evident GPS antenna input. > > I think the part with the GPS is the RFTG-M-XO which contains a > disciplined OXCO with optional rubidium input from the RFTG-M-RB box. > > I suppose there must be a EFC voltage input or, much more > useful, a 1 PPS input that syncs the Rb.
