ADS8900BEVM-PDK: Saturate the data to perform linearity analysis

Part Number: ADS8900BEVM-PDK

I am using ADS8900BEVM-PDK.

I tried to check the linearity analysis. I supplied 2kHz sinusoidal input signal from PSI injector. But I am unable to get the result (graph). It's showing "please saturate the data to perform linearity analysis".How to saturate the data ?

    Hi Aditya,

    To perform the linearity analysis, please saturate your inputs by providing an input slightly higher than the full scale range (35 mV above the upper limit and below the lower limit). If you are using the board in its default configuration (straight out of the box) when its full scale range is -5V to 5V, you should provide a -5.35 V to 5.35 V differential signal.
