 112 The USRP2 sink inputs 100 Megasamples per second / interpolation.
 113
 114 Input amplitude should be between 0.0 and 1.0.
 115
 116 To use the default ethernet device, leave interface blank. \
 117 For systems with only 1 USRP2, you may leave the mac address blank. \
 118 For multi-USRP2 systems, specify the mac address in the form 00:50:C2:85:3x:xx.
