Hi, We've achieved synchronized receving with two USRP2s with independent ethernet port. I'll report in another thread. Here we are beginning to build a MIMO transmitter. The question comes again regarding how to get the samples to two USRP2 aligned. I tried to set the timestamp of metadata in tx_sample.cc in order to schedule the transmit occasion. But it seems doesn't work. Still we are using external common 10MHz ref and 1PPS.
Thanks in advance. Bests, Hanwen
