Hi,
I am trying to make an architecture in which I need to use one streaming
channel with 10g Ethernet and the other channel over Aurora. I want to know if
I can pass the configuration of both channels from one 10Gig link and is there
a modification/tweaks needs to be done on UHD to suppo
Hello all,
The 3.10.2.0 release of UHD has been posted. This is an update to the main
series of releases. There were four commit between the release candidate
and the final release. All were documentation updates except for an
improvement to the query_gpsdo_sensors utility.
The tag for this relea
I currently have an x310 with a ubx-40 in each of slots A and B. I have one
10Gig Ethernet connection hooked up, and would like to receive on both channels
A and B.
I tried using the “rx_multi_samples” function, but I didn’t get a good feeling
I was collecting on both channels. I tried using
Hello Mark,
rx_samples_to_file will only receive a single channel. It is a minimal
example.
Try:
rx_multi_samples --channels 0,1
This will receive two channels, a pair of UBXs only has one RX channel per
daughterboard so UHD can infer the sub device specification. The default
sample rate is 100
Thanks Derek.
I was setting up rx_multi_samples the following way:
./rx_samples –args=”addr=192.168.40.2” –nsamps=1000 –rate=100e6 –sync=now
–subdev=”A:0 B:0” –channels=”0,1”
I see a lot of verbose output, like:
Received Packet: 1996 samples, 1 full secs, 0.50 frac secs
But, I don’t
What happens to samples between the ADC and receiving them from UHD? Also,
is there any way to get the raw IQ off of the ADC itself? I feel like
there isn't only because the ADC (to the best of my knowledge) runs at 100
MSPS which is too high a rate to send over the 1 Gb/s link.
Thanks!
Hi,
I am a new user of USRP and UHD software. I have 2 X310 USRPs but the
connection is established with only one USRP (first USRP). When I ping the
other USRP (say second USRP) it gives ICMP destination host unreachable
message. I am uncertain on how to debug or if there is something wrong with
i
Hello Adhitha,
If you are connecting only one USRP at a time directly to the computer and
see one work and one not then my first guess would be that the IP address
has changed on the second one. Try running uhd_find_devices, this will work
if the IP address is different but still on the same subne
Hi Mark,
Unfortunately you're up against the limits of the included examples. There
are no UHD only examples which store multiple channels of samples to a
file. The rx_multi_samples shows the steps involved in setting up the
channels, but doesn't implement the functionality shown in
rx_samples_to_
Hi Adhitha,
I'm glad that's worked for you.
Best regards,
Derek

Hi Dave,
You're exactly right, there is a decimation operation between the raw ADC
IQ samples and the samples which can be streamed *continuously* across a 1
Gigabit link.
It is very similar to the X310 where the frontend passes the full rate
samples to a DDC chain.

Derek,
Thank you very much for the information!! I am looking to see if the
ADC is clipping (or getting close to it) so being able to see the samples
directly off of the ADC is a plus. I'll take a look at those files and see
if I can make sense of things. Thanks!

Hi,
I am getting following error while I run compile and run init_usrp on
a machine running fedora. I have usrp with a modified ip but when I run same
from a Ubuntu based machine it works fine.
Error: LookupError: Path not found in tree: /mboards/0/xbar/Radio_0/ports/in
Any clues?

Hi Nauman,
that's not supposed to happen. So, I guess this is an X3x0, right?
Best regards,

Yes this is an X310 configured in a megausrp for massive mimo. Same device
works fine on Ubuntu but always makes this issue on Fedora, UHD is installed
correctly, no specific issues in installation.

Hi,
Has anyone tried to use Matlab with B205mini-i on windows? Apparently
Matlab does'nt recognise the board when plugged to USB 3.0 port. It however
works when used with USB 2.0 ports. Ettus recommends to use USB 3.0
specially on B205mini i.
Request for help

This is like not a MatLab-specific issue. What does:
uhd_usrp_probe -a type=b200
Produce when plugged in to a USB-3.0 port?

To All,
I realize this is a rookie question, but I looked all over on the net to find
the answer.
First off, I realize that thGNU radio and UHD.
So, I realize I need to create a pythin file offline via GNU radio Companion on
my laptop. And of course, do not include any graphical functions.

Mark,
There is an Ettus UHD-only utility called kitchen_sink that can do multiple
channels to file (either one file interleaved or multiple individual files,
I believe). This is not in the examples folder but in
"uhd/tools/kitchen_sink". This does not automatically compile with the
overall build
Hello -
I am using 2 USRP E310 which I would like to frequency sync together. I am
using a frequency generator which is generating a 1 PPS (1Hz sine wave) signal
which I put through a power splitter to provide both USRPs with the same 1 PPS
signal. I configured the rx_samples_to_file and tx_s
20 matches
