Matt, can you elaborate on the 20MHz bandwidth figure for the Flex400 and give some USRP application guidance? I have this "8MHz maximum supportable bandwidth" figure in my head which I think came from the sampling/decimation rates + USB2 throughput limitation discussed in the USRP documentation..? Some folks have seen the release below and are asking me if we can do XYZ in terms of bandwidth and I'm not sure what to say at this point.
Is there a way to move 20MHz-wide signals between the host machine and the Flex400?
