PPG testing equipment includes both physiological simulators for medical sensors and pulse pattern generators for optical communication modules.

Medical and Physiological PPG Testing

PPG (Photoplethysmography) is a non-invasive optical method to measure blood volume changes in tissue, commonly used for heart rate, SpO2, and vascular diagnostics . Testing equipment for medical PPG modules includes:

• AECG100 Wearable ECG & PPG Simulator: Simulates ECG and PPG signals simultaneously, including single green light or dual red/infrared light SpO2 signals. It allows adjustable parameters for Pulse Wave Transit Time (PWTT) and supports R&D, production, and compliance testing according to international standards (IEC 60601-2-47, IEC 63203-402-3:2024, YY 0885, YY 9706.247), .
• ADPD144RI PPG Optical Sensor Module: Optimized for SpO2 detection using synchronous red and infrared light measurement, minimizing ambient light interference and reducing power consumption .
• Viasonix PPG Systems: Finger-clip or other sensors detect reflected infrared signals to generate pulsatile waveforms for vascular assessments, including Toe Brachial Index, Venous Reflux, and Raynaud's evaluations . These devices are essential for validating sensor accuracy, signal fidelity, and device performance in wearable health devices.

Optical Communication PPG Testing

In optical communications, PPG (Pulse Pattern Generator) equipment is used to test optical transceivers and optoelectronic components:

• Quantifi Photonics BERT-1102: An 8-channel PPG and error detector for optical transceivers up to 28 GBaud in NRZ and PAM4 formats. Features include programmable 7-tap PPG Tx de-emphasis, continuous-time linear equalizer (CTLE), integrated clock synthesizer, and simultaneous lock-and-data recovery for each channel .
• LASER COMPONENTS MATRIQ BERT 1001/1005 Series: Dual- or four-channel PPG and bit error testers for development, characterization, and production of optical transceivers up to 30 Gb/s. Supports scalable multi-channel testing with high signal fidelity and graphical user interface control . These instruments allow engineers to characterize signal integrity, compensate for link losses, and perform high-speed optical testing efficiently.

Summary

PPG testing equipment spans two main domains:

1. Medical/Physiological PPG: Simulators and sensor modules for heart rate, SpO2, and vascular diagnostics, focusing on signal accuracy and compliance with medical standards.
2. Optical Communication PPG: Pulse pattern generators and bit error testers for high-speed optical transceivers, focusing on signal fidelity, error detection, and system characterization. Choosing the right equipment depends on whether the application is healthcare device development or optical communication system testing.
