Both use UHD, and both have access to the functionality necessary to synchronize the LO frontends in all four SBXes: First, you will need to sync the N210's reference clocks – for that, you will need an external clock divider (e. Comparemos los 50 MW de gasto con el gasto en energía eléctrica de Centroamérica. I had assumed from my previous experience using these devices with the Ettus FPGA that I would select some option indicating that I wanted to synchronize to the external PPS signal. You can use the uhd::usrp::multi_usrp::set_time_next_pps() function to either initialize the sample time to 0 or an absolute time, such as GPS time or UTC time. Ettus has an "Octoclock" which can provide synchronization for 8 B210s which would drive 16 antennas (8 eNBs assuming 2 antennas per eNB).
