I am trying to figure out why I cannot initialize an N310 from my host (UHD
4.6, Ubuntu 20.04). I get the following when I try to run uhd_usrp probe:
$ uhd_usrp_probe
[INFO] [UHD] linux; GNU C++ version 11.4.0; Boost_107400;
UHD_4.6.0.0-0ubuntu1~jammy1
[INFO] [MPMD] Initializing 1 device(s) in
I am trying to understand the OTW formats available on the X310. Does it
support signed complex 8-bit sampling (sc8 wire format) for a receive stream? I
am reading forum/listserv posts from ~2018 saying X310 does not support it on
account of the 10Gig link being enough to stream at 200Msps @ 16
I figured out the issue. I had forgot to set_time_source to the external PPS.
Although, I guess I should have figured that when I unplugged the ext PPS to
check its frequency and the PPS LED kept blinking...
Now it works :)

random times. For example, looking at
the received samples, the transmitted pulse that I know for certain is starting
with the PPS is being received at 0.1, 0.2, 0.3 seconds, etc.
How can I be sure that the USRP knows to sample directly on the PPS edge?
Has anyone had success with a 10GbE NIC other than the recommended Intel X520
card for the USRP-2944/X310?
And, does the USRP require 2xSFP+ for 200Ms/s RX capture, or is 1x SFP+
sufficient? I only need to rx on one mboard (UBX160) but at the max sample rate.
Thanks,
