 121 The USRP source outputs 64 Megasamples per second / decimation.
 122
 123 The "Receive Antenna Setting" selects one of the SMA connectors as the data source. \
 124 Flex RF boards use the "TX/RX" and "RX2" settings. \
 125 Basic RX and LFRX use the "RXA" and "RXB" settings. \
 126 All other boards use the "RXA" setting.
 127
 128 Flex RF boards only: If enabled, "Auto Transmit/Receive Switching" handles the preference for transmit packets vs receive packets. \
 129 By default, "Auto TR" is disabled.
