AFE4404: Questions related to the AFE4404 EVM GUI

Part Number: AFE4404

Hi Engineer

 I have a question while using AFE4404 EVM.

 There is a mode with heart rate like the picture attached to the AFE4404 EVM GUI.

I can not find that mode.

How do I get a waveform like a picture?

If you can not get into that mode, let me know how to check your heart rate.

thanks,

Taemin

    Hello Taemin,

    There is no specific mode to get this type of PPG waveform.

    Are you getting PPG signal from the finger? Also did you try on some other people?
    You could begin with the default register settings from the GUI and then adjust the LED currents or reduce the TIA gain (i.e. RF) or both to improve the signal quality.

    Sometimes you might also pick 50/60 Hz noise from the AC mains that affects the signal quality.
    In those cases, you can try using battery operated Laptop. Also you can enable notch filter in the GUI for reject 50/60 Hz.
