Community,

I've read all the faq and a lot of code (some codes i couldn't
understand, I learning c++ and verilog yet...) about  USRP2, but I
also have doubts.
They are,

1 - Is the DUC fully implemented in FPGA?
2 - Is the "complex modulation function"[page 38, AD9777 datasheet]
used?
3-  The function "set_tx_center_freq()" sets the carrier frequency as
tune() function does on usrp1, right?

Thanks for all,

Yes.

You can enable it if you want it, but it is disabled in the firmware
right now.

Yes.
