Re: [USRP-users] E312 Loopback Path Delay Changes when FPGA image is reloaded

Could you post your flowgraph or UHD program, or the relevant excerpts? Are the two RX channels being loaded simultaneously? Are you using timed commands to start the RX and TX streams? Nick On Tue, Mar 6, 2018 at 11:52 AM Prager, Samuel M (334E) via USRP-users < usrp-users@lists.ettus.com>

Re: [USRP-users] E312 Loopback Path Delay Changes when FPGA image is reloaded

Hi Nick, Thanks for the response. I am streaming from one channel at a time. I switch between channels by toggling: _radio_ctrl->set_rx_streamer(false, _radio_chan); _radio_ctrl->set_rx_streamer(true, _calib_chan); And then issue timed RX stream commands:

[USRP-users] OFDM TX/RX BER Calculator

Hi all, I am trying to use the ofdm_tx.grc and ofdm_rx.grc to transmit data from one N210 controlled by a host to another N210 controlled by a separate host. Eventually I want to build an 8x8 MIMO system using OFDMA. I want to verify that the correct data is being received so I sent all of the

Re: [USRP-users] OFDM TX/RX BER Calculator

Hi Sarah - A few things to note on using the default GR OFDM using real SDR devices that could be relevant here: * tx data amplification: This needs to be such that the data heading to UHD doesn't saturate on conversion. You can visually see this if you look at the raw Rx signal ... it will

[USRP-users] Synchronisation of 2 X310s with TwinRXs

Dear fellow users, I intend to put together a 8 channel data collection system using 2 X310s, each mounted with 2 TwinRXs. With the guidance from the past experience in this forum, I have installed the hardware and started data collection on a computer running on Ubuntu 16.04 LTS and UHD

[USRP-users] Hot Debug on E310

Hello, I'm trying to "HOT" debug on E310 with the JTAG, what I'm trying to say with HOT is burning the image but maintaining the OS functional for open the GnuRadio and test my RFNoc Module whit all the system running, is it possible ? because I'm experiencing some issues with it. To start whit
