Hi Irene, "U"nderflows occur when your application doesn't supply samples fast enough to the USRP. This is well-reflected by the fact that with the lowest sampling rate things work. Now, there might be different reasons, and the most prominent one is that your data source ultimately doesn't provide any faster. Also, if your processing is very complex, your computer might become a bottleneck. Often, people get confused and use the "throttle" block in a flow graph that actually contains hardware. Never ever do that! Best regards, Marcus On 06/04/2015 10:31 AM, irene menicagli
