I’m receiving a wide bandwidth signal (\~250 MHz sample rate using DPDK) on X410 using GNURadio and I notice that the green LED light turns ON and quickly turns back off whenever I have signal processing blocks (e.g. filter block) connected to the UHD source block. You have 1-2 overflows at the beginning but the GUI seems to work fine showing the signal with the time/freq sink plots. Whenever I just have the time/freq sink blocks only connected to the uhd_source, the green light stays on.
My question is would the green light turning quickly off be still an issue? If so, any ideas how to resolve that one? I’m wondering because I will need to re-transmit the signal again using UHD sink block and am experiencing underflows (not been able to resolve this yet and the red transmit light doesn’t turn on). I’m wondering if that’s partly due to the green light turning back off.
