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

Transmittance SpO2 Module

Works with the AECG100 main console or SECG 5.0 AIO Multi Vital Sign Simulator 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.

  • Works with the AECG100 main console or SECG 5.0 AIO Multi Vital Sign Simulator 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
  • Built-in 14 types of ambient light signals 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 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
  • Adjustable PPG waveform characteristic points, such as the Systolic Peak (SP), Dicrotic Notch (DN), and Diastolic Peak (DP), in a wide range and precise values for flexible test settings (1)
  • Exclusive Auto Test SpO2 Mode (2) – 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 (1)
  • 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 (1)

(1) Only available when paired with the AECG100.
(2) 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 and SECG 5.0 AIO test systems adjust 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) When used with the AECG100, it supports normal mode, standalone mode, and raw data mode; when used with the SECG 5.0 AIO, only the raw data mode is applicable.
(4) PD response time varies with the light intensity of the DUT.
(5) The SpO2 parameter specifications apply to SpO2 Test Mode.
