PPG-2TF-660 Transmission SpO2 Module
The PPG-2TF-660 works with the AECG100 main console and software, as the first transmission SpO2 performance tester designed for R&D in oximeter manufacturers. This dual-channel optical module outputs R and IR analog signals to test heart rate and blood oxygen saturation (SpO2) functions; provides transmission rates that simulate 5 finger types varying on color brightness and thickness, and neonatal foot test mode for measuring newborns; simulates 14 types of indoor and outdoor ambient light signals. It’s suitable for the development of transmission PPG products such as finger clip oximeters and patient monitors to test performance.


  • Works with the AECG100 main console and software to test heart rate, PPG, PWTT, and SpO2 functions
  • Adjustable SpO2 parameters, such as AC, DC, and PI values ​​of R/IR, to confirm the accuracy of oximeters
  • Exclusive Auto Test SpO2 Mode - automatically calculates the DUT’s DC value of R/IR and fills in the SpO2 table to rapidly build the R curve, bringing convenience for testing the consistency of quality on oximeters
  • Built-in 6 transmission rates - simulates 5 finger types varying on color brightness and thickness, and neonatal foot test mode for measuring newborns to optimize algorithms
  • Built-in 7 types of noise, 14 types of ambient light signals, and respiratory variation simulation - add-on signals for a more authentic testing
  • Adjustable PPG waveform parameters (R/IR amplitude, time, and heart rate) in a wide range and precise values for flexible test settings
  • 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 MCX to BNC ports 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-2TF-660, and the switch status of R/IR LED of oximeter
