Re: [USRP-users] N310 SFP+ ports not working (no green light)

I just followed the online KB guide exactly (I think). I have a successful serial connection and RJ45 connection. Here is the output from updating the HG (default) image (over RJ45 connection to host laptop). root@noiselab-10gig-1:/usr/local/share/uhd/images# uhd_image_loader --args type=n3xx,

Please follow the N310 Getting Started Guide on the Ettus Research Knowledge Base. Do not follow the printed Getting Started Guide that was included in the N310 box. The on-line guide should work for you. Please let us know if you're able to make any progress. --Neel Pandeya (sent from my Android

[USRP-users] N310 SFP+ ports not working (no green light)

Hello, I have an N310 running UHD 13.0.0 internally with an updated fpga image. My host machine has UHD 13.0.0 and GNUradio 3.7.12.0 compiled and installed from source. I can not get either SFP+ port to work. The light will not turn on when the adapter and Ethernet cable are plugged in. This

Re: [USRP-users] Time alignment failure for four channels coherent receiver in X310

Hey, have you tried starting the RX streamer a little bit in the future, i.e change the following lines: stream_cmd.stream_now = true; stream_cmd.time_spec = uhd::time_spec_t(); to something like (out of the top of my head): stream_cmd.stream_now = false; stream_cmd.time_spec =

Hi Marcus, Even I used 1Msps or less than this sampling rate, I still saw this time alignment issue. When I am using GNURadio system with python script instead of using UHD API, I can run 10Msps for my 4 channel phase array receiver without any problems. My final goal is to have 50Msps for my 4

Try an image from here: https://www.dropbox.com/sh/4w19l8ixwm2ke24/AAB3aGPAkjqe9SvG32TsyK5Ia?dl=0 pretty sure they include python-six. If not, I can easily add it. Philip On 07/29/2018 01:42 AM, shachar J. brown via USRP-users wrote: > Hi Everyone, > > I have noticed the previous discussion

Hi Everyone, I have noticed the previous discussion on the matter from February 2017, but seemingly there hasn't been any resolution. I have worked up till now on B210 and X310. I am now trying to set up a brand new E310. I carefully followed the instructions given at
