An up-to-date compact high-tech device ensures high quality wireless data transfer (via Bluetooth), data recording (EEG and other electrophysiological signals) to the portable computer of the Electroencephalograph and long-term storage onto internal storage (Flashcard, MMS or SD).

The number of inputs and types of signals being recorded depend on modification of autonomous patient block and can be extended by using polygraphic channels compander.

22-bits "delta-sigma" analog-to-digital converter of signals is used. Digital processing of signals is performed by high-performance processor TMS (Texas Instruments).

Uninterrupted measuring and recording of under electrode impedance and interelectrode potentials guarantee constant quality control.

With the help of special miniature calibrator all necessary checkouts and tests executes effectively and quickly in order to estimate the quality of device's functioning.
