The XO unit is different from the one in your message title (RB has an
LPRO rubidium inside). I don't have an XO unit but I think it is the one
that has a GPS receiver inside. I don't think I ever heard of anyone
getting either the RFG or RFTG to work in their original configurations,
(interconnected with the other units.)
I think the output they make is 15 MHz derived from the internal 10 MHz.
Maybe some of them have 10 MHz output too.
There was lots of discussion about these a while back. You might try
going here:

and do some searches. (Say RFG, RFTG and maybe LPRO if you have the RB.)
For my RFG-RB unit, I decided that most of the internals weren't that
helpful but the LPRO rubidium could be used with some other circuitry
driving it.
