WHALETEQ Reflectance SpO2 Module

Support PPG-2R-880 / PPG-2R-940

The PPG-2R-880/PPG-2R-940 is designed for R&D use in manufacturers and is compatible with the AECG100 main console and software. This dual-channel optical module outputs R and IR analog signals to test blood oxygen saturation (SpO2) and heart rate functions. It also allows users to individually adjust the R/IR’s rate of change of respiratory signals in PPG, as well as set up add-on noise. It is suitable for the development and verification of reflectance PPG products such as wearable devices to test performance.


  • Works with the AECG100 main console and software to test heart rate, ECG, PPG, PWTT, and SpO2 functions
  • Outputs R and IR analog signals to simulate SpOsignals
  • Adjustable SpO2 parameters, such as AC, DC, and PI values ​​of R/IR, to confirm the accuracy of the SpO2 function
  • Adjustable PPG waveform parameters (R/IR amplitude, time, and heart rate) in a wide range and precise values for flexible test settings
  • ECG function with adjustable PWTT parameters to verify the accuracy of blood pressure measurement algorithms
  • Built-in 7 types of noise and respiratory variation simulation - add-on signals for more authentic testing
  • Equipped with Auto Sequence function - sorts the parameters of different test items into a designated order for automated testing while eliminating the need to develop automated testing programs
  • Raw data playback - plays recorded raw data or customized waveforms for repeated verification to facilitate the development process
  • Provides SDK supporting multiplatform for users to flexibly develop automated testing programs
  • Equipped with an RCA to BNC port to connect to an oscilloscope - outputs amplified and stable signals for viewing the voltage of AC analog signals of R/IR, optical signals received by the PPG-2R-880/PPG-2R-940, and the switch status of R/IR LED of DUT
