Marcus is correct, you need to upload an FPGA image that has DUC/DDC
enabled to get arbitrary sample rates in/out. Try using uhd_image_loader to
put the X4_200 image on, which I believe does support DUC/DDC. Then try the
5 MHz rate

Thanks. I don't have
I'm working on the same thing, so yes this would be super useful.
Does Ettus Research have any update on that GitHub issue #666?
