I have no problem on the Lime (with int12 instead of int16, but with 2
channels instead of 1).
Is it possible to stream at 56MS/s on a single channel on the B210

Hi,
I am getting some unexpected behavior from my N310 using the example
'tx_waveforms' utility and stock FPGA image using 'rfnoc-devel'. If I
simply switch to 'maint', things behave as expected. Here are the issues...
1. With 'rfnoc-devel', it is necessary for me to specify a subdev spec
Hello all
When a multi-usrp object is first created, what purpose do the created
threads serve? I'm just curious on their role, what kind of cpu utilization
they need, and what level of cpu priority they need if the computer is
under heavy load. Thanks.

Hi,
I am doing RFNoC development for the N310 and it is not clear to me why I
would want to use rfnoc-devel as opposed to master. I know that the RFNoC
getting started guide talks about using rfnoc-devel, but I would still like
to understand better why I should be using that instead of master and
Ian,
We are using multiple B210 radios. We are monitoring two PPS signal (one
per radio) reclocked in the radio/sample clk domain on the scope. So
essentially, we are indirectly monitoring the radio clk/sample clk from two
different B210s, which always seem phase aligned over multiple reboots.

Dear USRP folks,
I've just unpackaged an OctoClock-G CDA-2990. I googled instructions in the
Ettus web page: https://kb.ettus.com/OctoClock_CDA-2990
However, the part I was most interested in does not have any links:
- *Where can I find user manuals for the OctoClock and USRP*

Hi Marcus,
Thank you for your comments, although this scares me a bit.
Obviously storing samples at 1.6 GB/s will not be easy to achieve, or at least
it is not straightforward.
I will wait a bit with further responses, I hope that someone else tried to do
same.
Is it possible to use Dual 10Gb
Hi Tarik,
I didn't try to continously stream to storage of dual-channel full-rate
X3x0 recordings myself, but I do have some experience to share;
hopefully it helps more than it scares.

make sure your write rate is *reliably*
Hi Kirthana,
yes, Ettus just announced that API! For much more info, see:

You will need to build UHD yourself with the mentioned flags to get it.
However, it'll be a little bit harder than necessary to get it to
Hi All,
I did further research on issues related to streaming and storing IQ samples
from USRP X310 (with UBX-160) sampling at 200Msps to PC.
The connection between USRP X310 and PC would be over two (2) 10 Gigabit
Ethernet interface.
Based on my calculations writing speed to the memory of PCs
