USRP1 reclocking

hi

I’ve found some OCXO clocks on ebay:


Maybe someone with enough knowledge can tell if this clock will work
with USRP1?
(I am researching on my own too)

I’ve just bought the board fairly recent, so believe it is rev.4
Does the information on this page still apply:
http://gnuradio.org/redmine/projects/gnuradio/wiki/OpenBTSClockModifications

One more question:
If I replace the clock on USRP1, will all the software (or hardware)
(or some combination) mistake frequencies? (or some parameter)
How does the hardware know itself is powered by some frequency of
clock and not another clock?
Is there a central place to communicate this info to hardware and
software?

Thanks

If you are using UHD, these are the instructions to inform the software
of the new clock rate:
