Hi Ali, I'm a bit confused about the disconnect between your subject line and your question.
The BasicTX is really just a transformer; see its schematic on https://files.ettus.com/schematics ; the schematic is so simple that we never cared to do a block diagram. The USRP1 (or: any device in this world) can indeed only generate signals within the Nyquist band of their DAC. You need to filter out the first nyquist zone and use the spectral images at multiples of the master clock rate. Band-pass undersampling for the win!
