  • 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)
  • Raw data playback function assists to validate heart rate monitoring system and improve 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 user to develop customized or automated test software with less efforts

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 3 of them as preset parameters.
2. Lumen accuracy would be ±10Lux when the light source is lower than 400Lux.
3. We suggest user to observe PD’s analog signals via connecting HRS200’s BNC port to the oscilloscope. Under High Resolution Mode, user requires to check “LED Off” option to switch off HRS’s LED and no optical signals will be sent then.
