Hello Chad: By "dual 10 Gigabit Ethernet", we mean that both Port 0 and Port 1 are being used with 10 Gigabit Ethernet links simultaneously. Both links must connect to the same host computer; you cannot have one link connected to system A, and the other link connected to system B.
In GNU Radio, you can receive from your SBX by using a USRP UHD Source block, and you can transmit with your WBX by using a USRP UHD Sink block. --Neel Pandeya On 17 November 2017 at 08:33, Chad Spooner <cmspoo...@nwra.com> wrote: > Neel: > > Thanks very much for the helpful reply. > > MY x310 has both a SBX and a WBX installed.
