(1)
BPM:
Adjust for different heart rates. The value is from 10 BPM to 300
BPM.
(2)
Output Waveform Parameter:
Adjust voltage and time parameters of
standard waveforms and pulse waveforms.
(3)
Output Waveform Selection:
Select to output different waveform
types (ex. PPG, Sine,
Triangle, Square…)
.
(4)
Noise Simulation:
To simulate noise with different frequency and
amplitude.
(5)
PPG Config:
Refer to 4.1 General (1) PPG Config.
(6)
Setting:
Refer to 4.1 General (2) Setting.
(7)
AC Offset:
Shift the signal upwards by the value of AC offset.
(8)
Respiration:
Add respiration modulation to the PPG function. Baseline
Modulation (BM), Pulse Amplitude Modulation (AM), and Frequency
Modulation (FM) are the available signals for breath modulation.
i.
Baseline Modulation (BM)
: Change in intrathoracic pressure when
breathing causes changes in venous blood return, which changes the
baseline of PPG
[1]
. Also called DC modulation.
ii.
Pulse Amplitude Modulation (AM)
: The heart axis deviates when
