PPG heart rate simulator

HRS200

Advanced PPG heart rate simulator to verify accuracy and algorithm of wearable with heart rate measurement function. Suitable for R&D and 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 behavior and brightness

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

Raw data playback function assists in validating heart rate monitoring system and improving algorithm effectively

Command mode function allows to conduct test quickly and repeatedly

Noise simulation with adjustable amplitude parameter

Playback capability of 40 clinical-recorded PPG databases. 25 PPG records are with arrhythmia symptoms as AF, APC, VPC and 1st AV block

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

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 users 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 HRS200's BNC port to an oscilloscope. Under High Resolution Mode, users need to check “LED Off” option to switch off HRS200's LED and no optical signals will be sent then.
