Hi Christopher-
One additional suggestion is to please be sure that you are using the default Visual Analog 'canvas' as the starting point for your data analysis of AD9625. This can be found by selecting (from the menu bar at the top of Visual Analog) File -> New -> Categories: Single: AD9625 -> Template: FFT.
This will ensure that the input formatting is correct at the onset and a solid basis for testing the evaluation setup.
Once you are sure that this canvas is working for you, then you can alter the data routing for any particular analysis that you need to take.
Thanks,
Ian Beavers
