I've removed the incorrect dbs_tx.py code so that it'll never confuse another person ;) The simplest tx example (which is much more complicated than you are looking for) if fm_tx4.py. It generates N FM modulated signals. It also has a dependency on some audio files which aren't supplied (yes, this is bad). However, it does handle all the daughterboard and mux correctly. sig_source_c to usrp.sink_c should work fine. Just be sure to copy the setup code correctly. You could also take a look at usrp_siggen.py. Note too that the output from the Basic Tx daughteboard is very low, about 50mV.
