If you have two daughterboards you can send two independent signals.
If you start fresh from USRP power-up you can control the phase
between the transmitted signals (this also depends on the
daugherboards that you are using and how they are configured.) The
power-up requirement is because from software we have no way to
control the phase accumulator in the AD9862 digital upconverter,
however at power-up it has a constant value.
