I am testing AFE4490 EVM and with the results from the DeviceAnalysis : Vpp, Vrms and Mean(V) how can I calculate the Spo2? Or shouldn't I use these values to get the result?
My problem is to find the DC and AC values to calculate the ratio.

Sandra,
You don't need to use those values. The AC and DC component can be found from the PPG signal on the GUI. Also, I have included this link to another e2e post that discusses how to calculate SPO2.
