Hi Marcus,
1.yes,we read it.But we could not find about a external devices.It is
possible that one of tx port of N310 as external LO when achieve 4 channels
sync receive?
2.From here:

we know that the SFP+ (sfp0,

Hi all,
We know that external LO is needed when we want to sync 4 channel of
N310.So Ettus supply the external LO or some advice?
Another quetion,if we want to directly connect via the SFPs and
operate N310 as X3xx from a host,how set that?

Thanks for the quick reply guys.
Marcus the Re-sampling option makes perfect sense, and I believe, in
theory, since I am writing data to a file for later use I could
interpolate it just before writing then read it out at the usrp sample
rate, right?

I noticed the following in the notes for release candidate 3.11.1

So, I tried out these functions. They seem to have been implemented with
the index meaning "daughterboard" rather than "channel" because they fail

Hi Martin,
Do you know whether the recently-announced release "3.11.1.0 Release
Candidate 1" addresses the bug discussed in this thread? Or should we keep
all our machines on 3.10.3 for now?
Thanks,

The release candidate of UHD version 3.11.1.0 has been tagged and is
available for testing. This is a maintenance release with many bug fixes,
mainly affecting N3xx, X3xx, and B2xx devices. This release is API
compatible with 3.11.x.x releases, but has a new ABI due to some
refactoring of the code
I did an experiment and the values match pretty much exactly what theory
would predict.
I don't have a splitter, so I used a 1m cable on the channel A of my B210
as my reference, and compared a 1m and a 2m RF cable on channel B.
The 1m cables have a velocity factor of 0.83 (enforcer SI-195), and
13 matches
