ADRF6720 Built-In-Test

I have a question about how I can perform a BIT test on the DAC to IQ modulator hardware.  I would like to verify that the DAC is outputting something to show that it is somewhat functioning.  In the past, we have commanded the output of the DAC from 0 to high and saw that the PLL would unlock.  Is there some sort of register or test I could perform that gives me confidence that the DAC is outputting something?

    Hello,

    It sounds that you want to confirm and verify the functionality of DAC through a BIT Test tone. Some DACs have the functionality to generate a test tone as a BIT test tone. If it is the case, please post your question at the "Dataconverter-High Speed DAC" section.  

    Thanks

    Hello,

    Is there still an issue? If there is, I suggest posting a different question for a BIT test in a specific DAC you are using.  Then when there are DAC outputs in quadrature signals to drive ADRF6720 inputs in quadrature I and Q, we can move to a next step. There is no Built-In-Test functionality in ADRF6720. 

    Thanks
