AFE4900EVM: GUI acquisition tab, channel 4 (ambient) not capable of showing a signal from LED4

Hello,

I am trying to use the EVM GUI to acquire a signal from a 4th LED on the ambient channel instead of an ambient. The LED is illuminating in at the correct time, but the display and saved output of the channel always seems to show an ambient signal around 0. When the photodiode is saturated if even shows a flat line at zero. When I switch one of the other channels to read in the same window, that channel measures the signal as normal. It seems that there is some processing being applied to that channel that removes any signal. Can you help me to have that channel display and save just like the other 4 channels?

Regards,

Alan
