[USRP-users] Using DDC/DUC frequency in RFNoC

2020-02-13 Thread Adria via USRP-users
Dear all, I'm trying to tune the output and input frequency of an X310 + UBX-160. I instantiate the radio block and the DDC and DUC blocks and connect them. The TX chain is like this: [Signal generator] -> [DUC] -> [Radio block]. My intention is to use the DUC only for frequency tuning, since

Hi Andrew, Are you able to run any of the in-tree RFNoC blocks on your E310 without this error? Does your block work if you make it 1 input / 1 output? Also, do you have access to an X310? If so, can you try running your block on there and see if it works? Jonathon On Thu, Feb 13, 2020 at 7:10 A

Hi, I am trying to solve what I think is a timing issue with my RFNOC design.  I have an E310 running UHD 3.15LTS/GNUradio 3.7/gr-ettus. I have created a custom RFNOC block for GNUradio without much custom logic, I've managed to just reuse code blocks from the uhd-fpga repo in lib/rfnoc.  In p
