Well,
The signals are just voltage readings from phototransistors, measuring specific ranges of radiation.
The sample rate can be slow, maybe every 10ms? even every 100ms would be OK I would think.
The number of channels should be at least 5, but up to 10 if possible.
We want to store this data to compare with other measurements taken during the experiment(for now). So just storing these values in an array on a computer, ideally in Excel would be great.
