Not sure I fully understand what you're trying to do. Generally speaking we downconvert to complex basebase. In this case you'd just tune the usrp front end to the desired center frequency. It would will end up at zero. u.tune(...) See for example, usrp_wfm_rcv_nogui.py > Other question: Is it possible to set the A/D frequency conversion? No. It's determined by the oscillator on the usrp motherboard.
