Hello,
I’m using the evaluation board EV-ADF4159EB1Z to understand how the ADF4159component works and how to program it. I use software ADF4158-59 dated 28.01.2016.
Using the default parameters of this software and disabling all modulation I can to shift the carrier signal from 10.6GHz to 13GHz.If I set 12GHz carrier, I have the VTUNE output fixed continuous voltage of 5V . If I set 13GHz carrier, I have the VTUNE output fixed continuous voltage of 13,66 Vdc. I noticed that setting the MUXOUT to have in output DIGITAL LOCK DETECT the led D1 is on .

 

 Question1:by using this evaluation board EV-ADF4159EB1Z with software ADF4158-59 dated 28.01.2016 I would like to know if in addition to write all  registers,  using this evaluation board, can I also read all registers ,using this evaluation board?.

Can I write and read the ADF4159 registers using this evaluation board EV-ADF4159EB1Z and  using the software ADF4158-59 dated 28.01.2016?.

Question2: if I set  MUXOUT to have in output DGND , using this evaluation board EV-ADF4159EB1Z and  using the software ADF4158-59 dated 28.01.2016  , why the led D1 is on ?.

Can anyone to answer to my questions?
