Ahhh, I missed the “full rate” definition, thanks so much for clarifying ☹

Hi Bob, This is expected with the CG_400 because it does not have the DDC/DUC blocks due to the high resource requirements for handling 500 Msps. If you want 500 Msps, use CG_400. If you want 250 Msps or lower, use X4_200 (or another _200 variant). Take a look at the FPGA image flavors in the X410 manual for an overview. https://files.ettus.com/manual/page_usrp_x4xx.html#x4xx_updating_fpga_types Wade On Wed, Jun 8, 2022 at 3:08 PM Marcus D.

If not, something seems to be amiss, any suggestions?
