[time-nuts] strange hp 5345A option C19

Dear all,

     I have bought an HP 5345A. It’s ok and I’m very glad. On the rear
panel it is wrote "OPTION C19" (a little bit strange!) and there are
two additional BNC installed on the little panel normally used to
place the HPIB connector when present.

These 2 BNCs are named REF OUT and REF IN and there is a jumper cable
that connects the output to the input.

It seems to be a modification made by some user (very strange: I can’t
understand why to place an extra auxiliary bypass for the 10 MHz
reference).

Do you have an idea about this strange modification and about the
strange option C19? Could it be a custom option? Could the option C19
and the 2 BNC for the reference be related?

Thanks

Bye
