For synchronizing 4 channels(2 TX, 2 RX) in the USRP X310, I read the manual[1] and perform the following. set_time_unknown_pps() set_tx_rate(rate) set_rx_rate(rate) uhd::time_spec_t cmd_time = usrp->get_time_now() + uhd::time_spec_t(0.1); usrp->set_command_time(cmd_time); usrp->set_tx_freq(1820e6, 0); usrp->set_tx_freq(1820e6, 1); usrp->set_rx_freq(1725e6, 0); usrp->set_rx_freq(1725e6, 1); usrp->clear_command_time(); 1. I'm wondering that is this enough for synchronizing 4 channels in the USRP X310?? 2. Do I need to set sampling rate simultaneously? Like frequency? For example, uhd::time_spec_t cmd_time = usrp->get_time_now() + uhd::time_spec_t(0.1); usrp->set_command_time(cmd_time); set_tx_rate(rate) set_rx_rate(rate) usrp->clear_command_time(); Thanks.
