Hi,
We recently investigated a similar issue and have a clear understanding on what
this comes from.
Commands sent by PC to usrp device are responded with an acknowledge. Each
command has a sequence number and is sent asynchronously. On the receiving side
there is a check on acknowledge sequence

Hello Markus,
Thanks for suggestion. Yes, I have two channels.
I don’t know if I am doing this correct, here what I understood from
your suggestion:
1^st Channel : Vector source (1,0)
2^nd Channel : Vector source (0,1)
So when 1^st channel will t
Hello Will
This sounds eerily similar to issues I've had using N200s. I basically
found that working at high rates, using either
STREAM_MODE_NUM_SAMPS_AND_DONE or using starts and stops was completely
unusable. The system would go into an unrecoverable set of timeouts or
overflows. I had to switch
Hey all,
I have built the latest version of UHD and am trying to load up my X300 but
having major issues.
I have used the image downloader script to get the latest versions of the
FPGA image and the image loader to burn the image successfully. Then when I
run uhd_usrp_probe I get to the DDC initia

Hi Martin,
Regarding the API version "guarantee", I am wondering if there is any way
to distinguish between versions. Presently, it seems that branches 3.12
and master both have UHD_VERSION set to 3120099. I had previously been

While working to get coherent streams working, I ran into an issue using an
x310 with two TwinRX daughterboards.
The issue starts with a series of "ERROR_CODE_OVERFLOW (Out of sequence error)"
errors. In an attempt to recover from that, the rx streamer is thrown out and
recreated. The next strea
Hey Sebastian,
this has been fixed on master branch
(8f16f05b20efcc9e5371c89585b992b237b43eb3) but not on a current release.
We'll remedy as soon as possible.
In a nutshell, there were product IDs that we didn't know about (but
were still valid) when we wrote the code, so we added the new ones

No, Ettus never followed up with a response and we never got past the problem.

About a year ago, we embarked on developing a similar application.
The TLDR is we never got to 2x200, but we did get 3x100, which to me is
actually a bit better cuz 2x200 is really only 2x160 with the analog filtering,
yet you have all those extra samples you have to take in for no benefit.
