Dear all,
For quite some time I have been trying to transmit a single byte in a
loopback scenario. I have the following questions:
1) Could anyone help me with an example about this?
2) Right now I am sending the digital data directly to the USRP Sink block.
Is this fine, or a one should send a di

Hi Varban,
GNU Radio ships with examples; typically, these get installed to
/usr/[local/]share/gnuradio/examples on Linux and similar systems.

Marcus,
In this setup I have 6 UBX-160 v2 and 6 UBX-40 v2. The USRPs are all
X310 Rev 11, Rev_compat 7. I have tried 3.13.1 as well as 3.14-rc3.
Thanks!

Marcus,
Thanks for engaging in this. I will have frequency deltas for you first
thing this afternoon.

Hi,
it is indeed a typo here. I did ping 192.168.10.2 first, and then I
tried on 192.168.10.3 to see if the error message was the same. In any
case (even using ping broadcast on all the sub network my computer is
connected to) i have this message. It looks like there is a connection
between t
Thanks, Nicolas. I am interested to hear how you eventually clear the problem
as I also have an X310 and so far all works fine but someday I may face the
same issue as you are experiencing so please when you find a solution please
post it. I am not experienced enough yet with mine to be able t
Hello,
Do you have any suggestions as to how to measure the frequency delta
between the transmit channel and the receive channel?
As I sat down to do this, I realized I have no real way to do that.

Well, according to your description, you could transmit a carrier from TX
to RX (through an attenuator) with both sides set to the same frequency.
Your received signal should look like a sine wave at the frequency of the
offset.

I wrote a blog post a while back describing a RX->TX RFNoC loopback
application. It should still apply to the latest UHD:

I can tell you the answer to #3 off the top of my head: the two streams
will be sample-aligned, and if you use timed start commands, they will be
time-aligned.
The other two are probably best answered by trying it out. Maybe someone
from Ettus can chime in.

Marcus,
190Hz is what we calculated. I have attached a text file with the
data we used. This is a single UBX40 tuned to 155MHz sampling at 2MHz.

would be useful.
