I am trying to test the mm wave transmitter and receiver HMC6300/6301. I followed the simple instructions in the user guide (ug-1031), but when I try to write the registers in the GUI by clicking on "Transfer" an error appears saying "WritewReadback : readback mismatch - I/O error." and the system does not lock (i.e. the "Locked?" light remains red).
This happens with both the receiver and transmitter (distinct motherboards too) and on three different Windows 10 machines. Does anyone have any idea what I am doing wrong?
