SEEG 100E
The EEG performance tester is compliant with the test requirements of IEC 80601-2-26:2019 and applicable for R&D, compliance and production line testing.
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 criteria
Software Development Kit (SDK) assists user to develop customized or automated test software with less efforts
