simply transmit a tone. I tried creating my own simple example

connecting that to the usrp.sink_c, and then connect the basictx
daughterbaord to an oscilloscope, but I couldn’t get it to work.
Any help would be appreciated.
I’ve removed the incorrect dbs_tx.py code so that it’ll never confuse
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,
