[USRP-users] B 200mini RX2 SMA

Hello group this is my first time posting has anyone seen the RX 2 SMA bad or out of spec? I can wiggle the cable and my NF drops 15db. It does not do this on the TRX sma. It also seems strange they didnt put a nut on the SMA to hold it to the case. Thanks __

[USRP-users] X310 calibration with WBX

Hi all, I haven't looked at daughterboard calibration in a long time, and picking it up, it sure looks broken to me. I'm using X310 + WBX on rfnoc-devel as of March. Let's assume for the moment I'm running a stock FPGA image -- I'm not, but for testing I replicated the same results on the stock im

Re: [USRP-users] RFNoC On B210

There is no conceptual reason why you can’t build an RFNoC design on B210, it uses the same USRP3 base architecture and FPGA source files….*HOWEVER*…. B210 is implemented with a Spartan6 FPGA and all the implementation work for RFNoC is done using Xilinx’s Vivado design tools which support only

[USRP-users] RFNoC On B210

Hi All, Is it possible to generate RFNoC blocks for the B210? I can't find a lot of information about it. Can some one show me the URL if there is a website talking about it? Cheers ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ett

[USRP-users] RFNoC FPGA clear_tx_seqnum behavior

I know this is an older thread, but I too am struggling to bring a block that someone else designed for us in 2015.4 to work in 2017.4. I dug around but I don't see any of our custom blocks using clear_tx_seqnum in their sub-modules or their config registers. They do use the config registers qu

[USRP-users] error to use the same RFnoc block twice in the same flowgreph

Hi All, I use RFnoc block and i run it with gnuradio on the X310. I have two different cases that I try to use the same RFnoc block in the flow graph and i get the same error. The cases are : 1. I want to create chain of fir block to minimize signal from 250M to 4M. in order to do it i want to cr

[USRP-users] X310 out of sync by 2 cycles

Hi everyone, I am still working on the synchronization of my two USRP X310. Both get the same 10 MHz, 1 PPS and LO signals. I made a small piece of code to toggle one of the GPIOs at the Aux I/O of each USRP in a timed manner: #define GPIOMASK (1 << 4) usrpDevice->set_gpio_attr("FP0", "CTRL

Re: [USRP-users] Synchronized frequency hopping

Hi Derek, I did what you suggested, but I have some synchroniziation issue between the two USRP. The four channels within each USRP are synchronized, but I get one out of three random phases between the two USRP at every start. Once initialized, the phases are constant. My code for setting th
