I have a PC with two PCIe express cards each of which has four Ethernet connections. I connect 6 USRP N210 to them. For shorter transmissions, like 80000 samples, I can do 25Msamp/sec on all simultaneously. But I have issues with latencies. I am using UHD driver version 3.3.2 still. I spent two weeks trying to upgrade a year ago - but it became insanely slow. I can't say for sure that I didn't do a mistake. I have a feeling that it has something to with long turn around times in my system (going from TX to RX ...). BR/ Per

Would you need eight separate ethernet ports? That seems like more than what a typical motherboard would be able to handle. Or can the USRPs all be connected to a server, which can be individually accessed through the host computer Understanding how to do this will be extremely beneficial in order to gather some ideas for a project. Thank you very much in advance, Rob -- View this message in context: http://gnuradio.4.n7.nabble.com/Sampling-with-multiple-USRP-N210s-with-one-host-computer-tp44502.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
