Frontend Specifications
Tuning
The RF frontend has individually tunable receive and transmit chains. On the B200 and
B200 mini, 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.
Gains
All frontends have individual analog gain controls. The receive frontends have 76 dB of
available gain; and the transmit frontends have 89.8 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.
Bandwidths
The analog frontend has a seamlessly adjustable bandwidth of 200 kHz to 56 MHz.
Generally, when requesting any possible master clock rate, UHD will automatically
configure the analog filters to avoid any aliasing (RX) or out-of-band emissions whilst
letting through the cleanest possible signal.
If you, however, happen to have a very strong interferer within half the master clock rate of
your RX LO frequency, you might want to reduce this analog bandwidth. You can do so by
calling uhd::usrp::multi_usrp::set_rx_bandwidth(bw).
The property to control the analog RX bandwidth is bandwidth/value.
UHD will not allow you to set bandwidths larger than your current master clock rate.
