I am transmitting a RF signal from one TX output to the 4 RX. The measures are right with the 2 RX which are in the same ad9361 chip that he transmitted signal, but in the others 2, I measure some noises which prevent me to have accurate measures. The problem is happening whatever the ad9361 chip which the signal is coming from, the signal measured by the 2 opposed RX will be noisy. This could be a problem of synchronization when I change the OL frequencies of the two ad9361 chips? Do you have any others ideas for solving this problem? I am using the last example design in my HDL and C code.
Thanks and best regards.
