Problem with capturing signal with zedboard + FMcomms3-ebz

ek123 on Feb 24, 2022

I`m trying to obtain a picture of signal like in a guide mentioned below,however i getting a picture like this.(Sending 115 Mhz signal from R&S generator ),tried different combinations of buffer size but it didn`t work.
Maybe someone will help to understand

Your signal generator and FMComms3 would need to share a clock to frequency lock them.

Are you expecting the signal to exactly start at +some level? What exactly is wrong with the signal you are receiving?

This likely comes from the fact that the FMComms3 and signal generator are not frequency locked. Therefore, your sinusoid will appear to be modulated. Can you zoom into your plot to better observe the transitions?
