 124 The USRP sink inputs 128 Megasamples per second / interpolation.
 125
 126 Input amplitude should be between 0 and 32767.
 127
 128 Flex RF boards only: The "Transmit Setting" must be configured. \
 129 When set to "Enable" the transmitter is always on. \
 130 When set to "Auto Transmit/Receive", the transmitter is disabled while receiving.
