The upconversion from complex baseband to the specified RF frequency
takes place in the USRP (actually a combination of the FPGA, AD9862 and
RF daughterboard).
I suggest you start by hooking up an oscilloscope or spectrum analyzer
to the output of whatever daughterboard you're using, and take a look at
the RF output with that.
Try usrp_siggen.py with a variety of options to begin to understand
what's going on.
