I use AD9361 & AD9634, only for transmission.
With both components I encountered the following problem:
Determining tx bandwidth using the appropriate function - does not work.
I work at a transmission baud rate of 2MS, and I want to set bandwidth to 20M,
but I get a bandwidth of 2M.
with AD9634, I solve it by disabling the filters (Register 2) but this is of course not the desired solution.
with AD9631 its not work.
I would be happy to help.
