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
