Yes, Somewhere in the Ettus documentation, it indicates that this is the case (I've forgotten where). > > Am I missing something? Have you gotten this to work? Yes, I have been using this in a 16x16 system with 8 N321 devices all connected by a single LO (arbitrarily chosen LO export channel distributed to both Tx and Rx LO inputs). I've also tested it on smaller systems as small as 4x4 (and possibly 2x2 like your case, but not positive on this). _______________________________________________ USRP-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
