Hi Dor, There are 2 arguments that can control the integer-N step size: the int_n_step tune arg and the dboard_clock_rate device arg. The int_n_step tune arg will explicitly change the step size by changing the R divider value, which will break phase coherency between channels. The 'dboard_cloc

Hi Maurizio, Compatibility number 33 indicates a fairly old version of the FPGA image, so it would be best to perform an update. To do this, run the command "/lib/bin/uhd_image_loader" --args="type=x300,addr=192.168.10.2" as per the error message, then cycle the power after updating the FPGA. Ch
