Strong signal at center frequence
Posted: Fri Sep 13, 2024 5:42 am
Dear BladeRF users,
I am currently trying to send a a video signal between the rx and tx of a bladeRF xa9 using a gnuradio3.8 programm. The signal has a bandwidth of 8 MHz, however around the center of the signal there appears a strong peak in the signal, which should not be there according to the produced signal of the software. Maybe there is an issue with the bladeRF? Maybe the bladeRF needs to be callibrated?
I am providing some more informations:
Gnuradio Programm:
Is there no method to upload files within this questions, so I need to post the content of the gnuradio file?
I would like to show you some pictures from the waterfall sink and I also would like to upload the needed example video file which shall be transmitted. How can I upload a file here?
Thanks a lot for helping me and all the best,
Jens

I would like to show you some pictures from the waterfall sink and I also would like to upload the needed example video file which shall be transmitted. How can I upload a file here?
Thanks a lot for helping me and all the best,
Jens
