My research group recently got an Ettus X410. We are wanting to connect to it through two MT27800 NICs on our server. We are able to set up the IP addresses on the server and running uhd_find_devices shows the USRP having the correct IP address that we are expecting. When we go to run the

I don't see any bypass logic in the FPGA code, but in any case, the N320 only supports three master clock rates, none of which is our desired sampling rate: https://kb.ettus.com/USRP_N300/N310/N320/N321_Getting_Started_Guide#Supported_Sample_Rates On Tue, May 30, 2023 at 11:44 AM Brian Padalino

Yes, bypassing the DUC was discussed among our team, but as far as I can tell, there is no way to configure the bypass via the UHD/USRP API - it would require an FPGA mod. On Tue, May 30, 2023 at 10:38 AM Brian Padalino wrote: > On Tue, May 30, 2023 at 11:15 AM Mena Ghebranious > wrote: > >>

Hi Marcus, I took a closer look at the end of my transmission; what originally appeared to be a lack of symmetry between the start and end delays is actually a cutoff of 31 samples at the end of the transmission - in other words, I'm missing the 31 samples at the end of the TX that I put into the
