Yes I am using the command: uhd::usrp::multi_usrp::make(args) passing the IP addresses of the three N200 boards. Moreover I check the boards synch using usrp->get_time_synchronized () which returns true but still the sinusoids are not temporally alligned. A colleague raised an arguement the even

Got it! The problem I sent before is now solved by exeplicity defining gain, frequncy and rate for the three cheannles as follows: usrp->set_rx_gain(gain,std::string(),0); usrp->set_rx_gain(gain,std::string(),1); usrp->set_rx_gain(gain,std::string(),2); and similar lines f
