AFE4420EVM: How to obtain maximum SNR using GUI

Part Number: AFE4420EVM
Other Parts Discussed in Thread: AFE4420

My question:

If I want to record from LED 1, 2, 3 all from PD2. (Ideally I want PD1 too)

I want to put the device on a wrist and optimize for the BEST SNR for the PPG from all LEDs. How do I do that?

What I want:

Can you send me a set of 2 configuration files to achieve my goal of getting highest quality data from the LEDs and each PD?

1.) LED 1,2,3, ambient on PD1

2.) LED 1,2,3, ambient on PD2

(all LEDs fired at separate times)

Config files that define all of the state machine parameters correctly and give me a starting point for using GUI knobs to get the rest of the way with the parameter tuning.

(But obviously that is just a starting point.)

Can you let me know the manual procedure to do the AGC using the knobs available to me on the GUI of the EVM? 

 

Issues I ran into:

It looks like the phases I can output from the GUI are fixed? I wasn't able to output the IR correctly when I set up the state machine to use LED 1, 2, 3. Do you see that same issue?
