Part Number: AFE4400 Hello，
Question 1:
Is there a detailed description of more than ten Count registers related to Timer in AFE4400 register? If yes, please help provide it;
Question 2:
Is there a reference algorithm for calculating blood oxygen saturation…
Part Number: AFE4400
At present, the problem we are encountering is that when EFT exists, there will be many glitches in the blood oxygen waveform. Put a magnetic ring on the blood oxygen probe, the quality of the waveform will be better, but the…
Hello Depeng,
Since I did not hear back from you, I believe you were able to resolve the issue.
I will close the post and if you have any pending questions, feel free to post them here.
