    Hi Linh,

    What is the input signal that you are applying? Can you describe the configuration of your signal generator and the connections that you've made to the EVM?

    Best Regards,

    Hi Ryan,

    I mean in data analysis tool, results are shown in graph in time domain tab is what I want to collect, but  in tab data inspector shows results like you see in the picture.

    Data inspector tab shows:

    Graph in time domain shows:

    I want to know how can I convert results in data inspector tab to the results in time domain tab.

    For example, at Count 0 ADC0 shows 910609. What does 910609 mean? I expect 0.xx V or something like that.

    Thanks you!

    Hi Linh,

    What you're seeing are the output data codes. Multiply 910609 by the size of the LSB and it will yield a voltage value like you are expecting.
