Dear Users
I am facing problem of phase offset when i change center frequency
dynamically for TwinRX with X310 setup. Here is my C++ code,
Please advise
usrp_source1->set_rx_lo_source("internal",uhd::usrp::multi_usrp::ALL_LOS,0);
usrp_source1->set_rx_lo_source("companion",uhd::usrp::multi_usrp::ALL_LOS,1);
usrp_sourceDOA1->set_command_time(usrp_sourceDOA1->get_time_now() +
uhd::time_spec_t(0.01));
usrp_sourceDOA1->set_center_freq(m_CenterFrequency,0);
usrp_sourceDOA1->set_center_freq(m_CenterFrequency,1);
usrp_sourceDOA1->clear_command_time();
I feel set_command_time is not working properly. When i start the X310
my phase difference is almost zero but as i change my frequency pjhase
difference is random in nature.

COuld you explain your setup a bit more here.
I now see that you have both usrp_source1 and usrp_sourceDOA1, but I
think you said that you have a single X310, so I'm confused about
why you apparently have two USRP sources here.
