Overview
The PPG-1R-525 works with the AECG100 main console or SECG 5.0 AIO Multi Vital Sign Simulator as the reflectance heart rate performance tester designed for R&D in manufacturers. This single-channel optical module outputs green light analog signals to test the heart rate function. It allows users to adjust the green light's rate of change of respiratory signals in PPG and set up add-on noise. It is suitable for the development and verification of reflectance PPG products such as wearable heart rate monitoring devices to test performance.

Key capabilities

• Flexible PPG waveform settings for detailed adjustment of characteristic points.
• ECG sync output to simultaneously send ECG and PPG signals and adjust Pulse Wave Transit Time (PWTT) parameters to verify blood pressure algorithm accuracy.
• Raw data playback to reproduce clinically recorded or customized waveforms for repeated verification.
• Respiration simulation function to superimpose respiratory changes on PPG waveform tests.
• Software Development Kit (SDK) provided to enable automated testing and development of custom test software.

Features

• Basic Waveform Output: includes ECG Waveform, Sine, Triangle, Square, Exponential, Rectangle Pulse and Triangle Pulse, adjustable parameters, and DC offset signal testing.
• PPG Signal Generation: simulates Sine, Triangle, and PPG analog signals; provides simulated signals of green, red and infrared light for reflective PPG heart rate and SpO2 measurement.
• Adjustable PWTT (Pulse Wave Transit Time): simultaneously outputs ECG and PPG signals, adjust time difference (PTTp, PTTf) between signals to verify blood pressure algorithm accuracy.
• Saving Test Parameters: save parameters of different test items for integrated testing to reduce human errors.
• Raw Data Playback: plays back raw data waveforms and reproduces clinically recorded or customized waveforms with high repeatability and reproducibility.
• Simple Automated Test: supports automated testing using software to control the testing process and manual editing of auto-sequences.

Highlights

• Simulations that are closer to time and real situations by providing respiration-change simulation and superposition to PPG signals.
• Raw data playback with high repeatability and reproducibility to reproduce arrhythmia and other pathological waveforms.
• SDK for flexible development of automated testing programs, reducing repetitive operations and human errors.
