PPG-2TF-660 Transmittance SpO2 Module
PPG-2TF-660 Transmittance SpO2 Module

Transmittance SpO2 Module

Works with the AECG100 main console and software as the first transmittance 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 and is suitable for the development of transmittance PPG products such as finger clip oximeters and patient monitors to test performance.

User ManualUser Manual


  • 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 in 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 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

*Note: This mode is mainly for developers to quickly test for reference, not for after-sales calibration and testing on oximeters. If users require development tests on SpO2 parameters and specifications, please use the SpO2 Mode.

§Data Collection Method: To connect the spectrometer with a 2-inch integrating sphere, and fix the integrating sphere on the DUT to measure the absolute irradiance of the LED of the DUT.

1. The AECG100 test system adjusts AC/DC output according to the linearity of LED electro-optical conversion.
2. The PI value may vary according to the different calculation methods of each manufacturer.
3. PD response time varies with the light intensity of the DUT.
4. The SpO2 parameter specifications apply to SpO2 Test Mode.
