Users +may select non-default clock rates to acheive integer decimations or +interpolations in the DSP chains. The default master clock rate defaults +to 32 MHz, but can be set to any rate between 5 MHz and 61.44 MHz. + +The user can set the master clock rate through the usrp API call +uhd::usrp::multi_usrp::set_master_clock_rate(), or the clock rate can be set through the +device arguments, which many applications take: : + + uhd_usrp_probe --args="master_clock_rate=52e6" + +\section b200_fe RF Frontend Notes + +The B200 features an integrated RF frontend. + +\subsection b200_fe_tuning Frontend tuning + +The RF frontend has individually tunable receive and transmit chains. On +the B200, there is one transmit and one receive RF frontend. On the +B210, both transmit and receive can be used in a MIMO configuration. For +the MIMO case, both receive frontends share the RX LO, and both transmit +frontends share the TX LO. Each LO is tunable between 50 MHz and 6 GHz. + +\subsection b200_fe_gain Frontend gain + +All frontends have individual analog gain controls. The receive +frontends have 73 dB of available gain; and the transmit frontends have +89.5 dB of available gain. Gain settings are application specific, but +it is recommended that users consider using at least half of the +available gain to get reasonable dynamic range. + +*/ +// vim:ft=doxygen: |
