Don't recall where I read this but IIRC:
There are several other options for the 53230A which can be added lateron
by the user ("kits") but the OCXO can only be installed lateron by sending
the device to service.
Thanks to the list for the answers - but:
It seems like everybody is telling me "go for the cheaper, add the OCXO
lateron if you need it" - but that's not what I'm after. What I'd really
like to do is to make up my mind based on educated opinions on this list
whether the built-in OXCO option offers any advantage at all compared
to standard clock + good external reference.
