To record a pulse waveform using the PPG100C, follow these setup and calibration details:
Plug the transducer into the amplifier but do not connect it to the subject yet.

Hint: Using the 3.0 Hz LP setting and the 0.5 Hz HP setting in conjunction will make it easier to find the rate of the pulse waveform (these filters can be applied in software as well).
Gain: 10 (lowest Gain option) = top position
LP: 3.0 Hz = top positionHP (first bank) : 0.5 Hz HP = top positionHP (second bank): 0.05 Hz HP = top position
Recommended acquisition sample rate: 100 Hz.
The following graphs show results of motion artifact and varying tension levels:

Are you interested in getting started with fNIRS?
fNIRS is growing in popularity as a tool for studying human cognition including workload, memory, learning, attention and more. It is simpler than ever to incorporate into your experiments.
You will learn how to:
– Operate fNIRS equipment
– Record high quality data
– Perform an experiment
– Analyze data
– Synchronize with other physiological signals
– Synchronize with stimulus presentation
