Hey,_______________________________________________I created a test branch for the AGC a few years ago. It should still work. You can find it here:Cheers,JulianJulian Arnold, M.ScInstitute for Networked SystemsRWTH-Aachen UniversityKackertstrasse 9

You cannot. We don't SWIG the multi_usrp object.but then the returned object (dev) has no interesting functions(only 'acquire', 'append', 'disown', 'next', 'own').Is there a way to control the USRP B2xx's AGC (AD936x's AGC) throughPython? If not, what should I change in the source code to make it happen?
You can extend usrp_source and usrp_sink to include AGC-controlling
methods. Mostly, they're simple forwards to the underlying multi_usrp call.
Cheers,
Martin
