I am trying to write a python script which will
allow me to take some 16 bit IQ samples
from a file and write them out to my USRP2/WBX.
The background is that I am trying to implement
what has been done on here
but instead taking the output of gbDVB piping it through
an app I am writing (to do the raised cosine filtering) then
piping that to the USRP2
Unfortunately GnuRadio is a bit daunting at the moment
especially finding what various things are especially as some usrp
blocks don’t seem to exist for the usrp2 or their input formats are
What I need to do is set the tx frequency to 1249 MHz
select the correct antenna output then pipe samples from
the input file to the usrp2 sink.
Any pointers would be most useful.
