Neel: But what does Ettus mean by "Dual 1 Gigabit Ethernet" on those links? (Not "Dual 10 Gigabit Ethernet".) See attached screen shots from the Ettus.com links I sent previously. I am currently using the UHD Source block with the SBX and a UHD Sink block with the WBX in the working flowgraph. What I want to do is occasionally obtain complex samples from the SBX and process them outside of GRC. I can think of two ways to get data from the SBX to a file. The first is through uhd_rx_cfile and the second is through the use of a File Sink in the flowgraph. But while the flowgraph is running, I can't successfully call uhd_rx_cfile. If I use the File Sink, I'll have to be able to grab samples at irregular intervals outside of GRC, and I'm not sure if that will cause a problem for the function that is continuously writing to the file. I'll try. Plan B could be to just use a second USRP.
