Re: [USRP-users] No output from OOT RFNOC Module

Hi, If your block is sending small amounts of bursty data the timeout being printed is irrelevant as it just indicates no data has been sent for a given time lapse not that no data has been received at all. Dario Pennisi On Wed, Oct 11, 2017 at 10:10 PM +0200, "John Medrano via

[USRP-users] Removing DC offset on USRP B200

Hello, I've implemented a DDS signal on the USRP device. In radio_legacy.v, I input get_tx_I and get_tx_Q as my I and Q channels. always @(posedge radio_clk) begin tx[31:16] <= (run_tx) ? get_tx_I[31:16] : tx_idle[31:16]; // I channel tx[15:0] <= (run_tx) ? get_tx_Q[31:16] : tx_idle[15:0]; //

Re: [USRP-users] Frequency offset between two USRPs B210 synchronized with use of Octoclock-G

Hi all, After discussion on IRC and few questions (by Brian Padalino and Marcus D. Leech), that made me not so sure about how I made the measurement, I found the reason for frequency offset. It wasn't fault of USRP B210 or broken cable providing 10MHz reference signal. The issue was a bit more

[USRP-users] RFNoC Block with 2 inputs and 1 output

Hi all, I am trying to create a custom RFNoC block with 2 inputs and 1 output. I have attached my block code as well as the XML files for the UHD and GNU radio integration. The block behaves as expected when I run the testbench. However, when synthesised and used within the GNU radio flowgraph

Re: [USRP-users] Help to configure/install PCI-Express Connectivity Kit for X310

Hello Daniele Disco: Unfortunately, at this time, the kernel driver for the PCIe Kit only supports up to kernel 4.2, and you are using kernel 4.10. Would you be able to downgrade you kernel, perhaps by using Ubuntu 14.04? We are working to add support for newer kernels to the PCIe driver, but I

Hi! With the X310 we have also taken the PCI-Express Connectivity Kit. Following the instruction reported here (http://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_hw) And going in the section : PCI Express (Desktop) that send to http://files.ettus.com/manual/page_ni_rio_kernel.html

[USRP-users] IQ samples being lost when using SOB/EOB

Dear All, I'm sending OFDM frames in a bursty manner, i.e., a have slots of 1 ms with 14 OFDM symbols. These 1 ms slots are transmitted from time to time and I'm using SOB and EOB to make it a busrty transmission. What I have noticed is that some samples at the beginning of the slot are being

Re: [USRP-users] RFNOC complex_multiplier not found

Hello Kau-Uwe, You have to point your Makefile where the IP is located so that it can build it for simulation. You can base this on the Makefile for the FIR filter, for example [1], where the IP specific settings are introduced. In your specific use case, it should be something like:

Re: [USRP-users] additional Verilog file in OOT RFNoC block

Hello Dixon, Daniel's suggestion works, but that would mean adding a hard-coded path into the fpga build system. It does the trick, but it is not recommended. The OOT module has its own Makefile.srcs that intends to contain all the HDL code that is required for the module. The procedure is the

Hi Jim, try to add the file multTest.v (with the complete absolute path) in the Makefile.srcs located at .../uhd/fpga-src/usrp3/top/x300/. At least this worked for me. Best regards, Daniel On 11.10.2017 03:45, Dixon, James L via USRP-users wrote: Hi, I am trying to figure out how to add
