Overview
- Designed for the latest EEG standard IEC 80601-2-26:2019.
- 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 80601-2-26 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.
