It seems to be sample-rate agnostic. I ran a few tests using GNURadio companion at 50M, 1M and 100K sample rates, they all had the same errors when stopping the flowgraph. For my application I need to run it at 50M.
After a few runs here I now have a new error too: RuntimeError: RuntimeError: BIST failed!(code: 1) The usrp flowgraph would not run until power cycling the usrp. Side note: the errors do not appear if I kill the flowgraph using the stop button, as opposed to closing it cleanly. ----------------------------- Jacob Knoles On Mon, Jul 9, 2018 at 10:02 AM Marcus D.
