Hi everyone, I already posted this to stackoverflow, but maybe somebody here can help me as well.
I’m working with a USRP B210/X310 and I’m trying to send a frame with containing some payload, with synchronization sequences before and after the payload. For interesting measurements bit error rate measurements, I want to get a low SNR for the payload. Since I need a much better SNR for more synchronization, I’m trying to send the synchronization sequence with a high gain, while sending the payload with a much lower gain. Trying to implement this I encountered some unexpected behavior while using the tagged stream commands for the GNURadio block. So I went back and made the most simple setup, I could imagine. The results and the actual problem can be seen in the screenshots in my stackoverflow post: https://stackoverflow.com/questions/75869595/gnuradio-usrp-stream-tag-execution-not-as-expected Any ideas, where to look for/how to remove the error? Thanks in advance, Nicolas Buhr
