Hello, Do you have multiple USRP's hooked up? If so, try only having one plugged in for this initial test.
You can provide a device hint in the arguments of the UHD source block. Try: "type=b200" As another test, make sure you can use the built in utilities of UHD to detect your USRP. uhd_usrp_probe uhd_find_devices You can also give a device hint like: uhd_usrp_probe --args="type=b200" -Trip On Tue, Jan 19, 2016 at 9:33 AM, Henning Bredenberg < [email protected]> wrote: > Hi all, > > i just started to work with GNU-Radio-Companion (v3.7.2).
