ADRF6720 Built-In-Test

aclee1 on Dec 6, 2019

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,

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
