Hi Sanjoy,
you're both setting the time for both the USRP with the GPSDO (which
will get it from GPSDO) and the one without. You don't have to do that,
remove these lines. There should be no set_time_** in your code if you
want to use the time as it comes from your GPSDO.
Then, although you
Hi Marcus,
I need help regarding the phase sync part that you mentioned in your
previous post here.
"There's one thing that could use improvement in the echotimer code: If
the set_?x_freq() were done after the time and clock sources had been
set as a timed command (i.e. after calling set_command_
Hi Marcus,
Thanks for the reply.
This worked today. Unfortunately set_command_time(),
clear_command_time() did not work well with my setup.
The Rx start point was varying with every initiation.
With the same code today I tried with set_start_time() and this worked
really well.
The time sync prop

Hi Marcus,
Thank you very much for the tips and suggestions. This is really
helpful.
You are right, I should not rely on Echotimer, rather I should try to
make one, based on my requirements.
First I tried the python code. This really worked for one X310 frontend
ports. I tried for 1Tx -2Rx and
This is just a wish, but it would be nice if the set_start_time sequence
shown below could be added to the UHD Sink and Source blocks in GRC.
Seems generic enough (with the delay as a variable).

That's absolutely possible! Two channels in the same X310 have the same
clock and time source.
For example, generate
Hi Marcus,
Thanks for the response. I did not get any notification in my inbox. So
I put it there.
I am trying to implement MIMO OFDM radar with X310.
With this, I am actually trying to achieve time sync for X310. With
separate UHD source and sink--I could not achieve time sync with

Sorry, Sanjoy,
we'll need some more information before we can give you better feedback.
It's not clear exactly what you're trying to achieve, and what exactly
is failing.
Perhaps this helps getting started:

Is there a particular reason you're creating your own block? Is there a

Hi all,
I am trying to make 2 TX 1Rx tagged stream block(OOT). For 1Tx 1Rx, it was
working fine. I am trying to extend it. Now the problem is, I am not being
able to configure the send() function.
If I try make test, it does not show any problem. However, when I check
after reception I find that
