PPG-2R-880 / PPG-2R-940 Reflectance SpO2 Module
The PPG-2R-880/PPG-2R-940 works with the AECG100 main console and software, as the first reflectance SpO2 performance tester designed for R&D in manufacturers. This dual-channel optical module outputs R and IR analog signals to test blood oxygen saturation (SpO2) and heart rate functions. Besides, it also allows users to individually adjust the R/IR’s rate of change of respiratory signals in PPG and set up add-on noise. It’s 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 SpO2 signals
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
