I have started using EV-ADF4360-9EB1Z through GUI provided with the evaluation board. As default the "RF Output Frequency" is set as 360 MHz. As per datasheet, primary output range is 64 to 400MHz. When i enter 200 as "RF Output Frequency" in GUI to generate 200 MHz frequency then output shows 297.7 MHz. It seems if i specify any value below 298MHz, RF output will fix at 297.7 MHz. Between 298MHz to 400MHz, I can specify any value and it is correctly generated at RF output. Same behavior can be seen in "frequency sweep" and "frequency hop" function provided in GUI.I am observing RF output using R&S spectrum analyzer. How can i generate output frequency from 65 MHz to 250 MHz using this evaluation board?
