Best price Used-good Parts of Masimo Radical 7 mainboard 31356 21035 pulse oximeter mother board

The Radical 7 motherboard performs key functions for the device's signal processing, parameter calculation, and system coordination. Through precise design, it achieves electromagnetic compatibility (EMC) performance, with a shielding effectiveness of ≥30dB within a specific frequency range, ensuring stable operation in high-electromagnetic interference environments such as ICUs and operating rooms.

The mainboard features:

• Optical signal processing module
• Digital signal processor
• Power management unit
• Communication interface circuitry

This mainboard is compatible with the entire Radical 7 series of pulse oximeters, including handheld models and desktop models with docking stations (RDS-1/RDS-3).

• The 31356 mainboard is compatible with standard models (SpO₂/pulse rate monitoring only)
• The 21035 motherboard is compatible with expanded models that support Rainbow technology upgrades

1. Multi-Parameter Signal Processing: Receives multi-wavelength optical signals from the sensor and digitizes them using an analog-to-digital converter, ensuring SpO₂ measurement accuracy of ±2%.
2. Real-Time Data Calculation: Performs over 1,000 complex algorithm calculations per second, with a latency of ≤200ms from signal acquisition to result display.
3. System Collaboration: Coordinates operation of various device modules including touchscreen display, key input response, battery management, and alarm systems.
4. Interface Expansion Support: Includes RS-232 serial communication ports and analog output channels for connection to monitoring systems.
