Dear all, I have a usrp x310 with two UBXs installed. And I want to use it as a MIMO transmitter (two outgoing channels streaming at the same frequency).
When we need to build a MIMO system by connecting different usrps, I know that we need to have either MIMO cable or external time and frequency reference. In the one usrp x310 case, since two daughterboards seems to be independent, do we need to synchronize them? or they are already synchronized by default (for example, two local oscillators are synchronized, and will be tuned to exactly same frequency?)? Thanks, Yang
