[USRP-users] Changing phase with TX->RX loopback

2018-07-16 Thread Andreas Leuenberger via USRP-users
Hello all, I am using a USRP X310 with a UBX-160 daughterboard. The transmit signal on port TX/RX is attenuated and looped back to the receiver on port RX2. Every millisecond I am sending a short rectangular pulse (about 10 us long) using the 'time_spec' attribute of the transmit meta-data ('st
