<doc>
The USRP source outputs 64 Megasamples per second / decimation.
The "Receive Antenna Setting" selects one of the SMA connectors as the data source. \
Flex RF boards use the "TX/RX" and "RX2" settings. \
Basic RX and LFRX use the "RXA", "RXB", and "RXAB" settings. \
All other boards use the "RXA" setting.
With the format set to 8 bits and the halfband filters disabled, the USRP can acheive a decimation rate of 4. \
Disabling the halfband filters requires a special USRP firmware without halfband filters or TX paths. \
For this reason, the USRP cannot transmit with the halfband filters disabled.
