OVERVIEW

Designed for the latest EEG standard IEC 60601-2-26:2012 and GB 9706.226-2021

Sophisticated electrical and shielding design enables the test system to output 1μV signal

9 channels with auto-select switches for user to test performance individually

Built-in test circuits as defined in EEG standards with selection of 620kΩ/4.7nF for input impedance test

Able to load and replay files in PhysioNet's EDF format, binary format and text format

IEC 60601-2-26 and GB 9706.226 helper simplifies the medical standard with test sequences, options, parameters and pass criterions

Software Development Kit (SDK) assists user to develop customized or automated test software with less efforts
