Hi Dario, There are other differences in the FPGA code as well, since X440 is designed for higher rates and channel counts. For example, the X440 doesn't have additional DDCs/DUCs in the FPGA fabric. I think the manual page does a pretty good job of summarizing the differences.
https://uhd.readthedocs.io/en/latest/page_usrp_x4xx.html https://uhd.readthedocs.io/en/latest/page_fbx.html https://uhd.readthedocs.io/en/latest/page_zbx.html Regarding the sample rates, the X440 supports configurable sample rates, down to 125 MSPS. So, you can do 200 MSPS without modifications, but 100 MSPS is lower than it supports. If 100 MSPS is the rate you need, then you might need to use 200 MSPS then add a DDC/DUC with a custom FPGA image. I think this is possible, but it's not supported by default.
