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 …).

Subject: [Discuss-gnuradio] Sampling with multiple USRP N210s with one
I recently discovered that Ettus offer a way of synchronizing up the
USRPs with the following clock distribution system:
Out of curiosity, how would one be able to connect and sample with eight
separate USRPs with one host computer. Would you need eight separate
ethernet ports? That seems like more than what a typical motherboard
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
some ideas for a project.
Thank you very much in advance,
