PPG waveform signals

HRS100+

PPG Heart Rate Simulator designed for wearable with heart rate measurement function. Applicable for production line testing.

Standard Coverage: IEC 63203-402-3:2024

OVERVIEW

Built-in LED outputs adjustable PPG waveform signals as the reflected optical signal of different human skin tones

Built-in photodiode can detect and display DUT LED brightness

Adjustable parameters includes heart rate (BPM), reflected skin brightness (DC), arterial blood volume change (AC) and Perfusion Index ((AC/DC) x 100%)

Command mode function allows to conduct test quickly and repeatedly

Software Development Kit (SDK) assists users in developing customized or automated test software with less efforts

SPECIFICATION

Note:

(1) Heart rate test range is different in standalone mode and PC mode. In PC software mode, heart rate range is 

from 30 to 300BPM; in standalone mode, heart rate value can be set to 30, 60, 70, 80, 90, 120, 150, 180, 210, 240BPM

, plus user can manually select other 3 values from 30 to 300BPM as preset parameters.

(2) Lumen accuracy would be ±10Lux when the light source is lower than 400Lux.

(3) We suggest users to observe PD's analog signals via connecting HRS100+'s BNC port to an oscilloscope. Under 

High Resolution Mode, users need to check “LED Off” option to switch off HRS100+'s LED and no optical signals 

will be sent then.
