AD9081 NCO Test Mode

Category: Hardware
Product Number: AD9081

I am trying to use the ACE GUI to simply use only the NCO to generate a CW tone. I select NCO Test Mode and direct clock at 12GHz. I also feed a 375MHz clock into the JESD clock input on the ADS9 to match the settings in the GUI. I don’t know if this is necessary considering we aren’t using JESD data in this instance. I have tried to play around with the Fine and Course DUC NCO Frequency settings, the power offsets, and even gone into the memory map and tried to manually set the bits. Nothing works.
