Transceiver board oscillators, external clocks

Hi,

When the master clock on a USRP2 is locked to a reference (external
source
or another USRP2), are the oscillators on the RFX or XCVR boards locked
as
well? Or do they generate their own clock? I have an application that is
very sensitive to clock mismatch (both sampling clock and
up/downconversion
clock) between transmitter and receiver, and I would like to synchronize
the
clocks on two USRP2s.

Thanks,
Jordan

All the daughterboards (other than the TVRX) generate their LOs from the
master oscillator, so everything is fully synchronous. You couldn’t do
MIMO if it wasn’t
