Now that I have my Eval Board setup, I plan to do some basic checkout over the next day. One of those things is testing the voltage measurement accuracy. I intend on looking at 0 to 5V for the following frequencies: DC, 1KHz, 10KHz, 100KHz, and 1MHz.
- I decided to use the "Data Grid" box to display the samples in both Decimal and binary (attached is my very basic .vac file). Is this the best way to view the samples? I was planning on analyzing the data in excel.
- Starting at a DC, 1V signal (into CHA), I am not seeing anything above 0V. Am I possibly overlooking a signal requirement on CHA or is something going wrong? Any ideas on how I can go about characterizing the ADC in this way?
I think that's it. Thanks a lot for your help!
