Neurocare-D EEG system integrated with function of real-time EEG signal collection in fiber optical transmission, 12 channels Polysomngraphy for sleep study and external acoustic&visual stimulator for Event Eelated Potential (ERP) examination and data analyse. It's a completed EEG system for EEG data acquisition, record, replay and analyse, ERP data acquisition, averaging and analysis, sleep data acquisition, replay and analysis

Features
1. Superb signal quality with fiber optical isolation. It transmit optical signal only and power line interference can be shielded. Meanwhile, data transmission bandwidth of fiber optical is better than ordinary cable, therefor, it can deliver high-speed, stable and safe data.
2. 24 bits A/D conversion rate, and it's sampling rate can reach to 8kHz.
3. Head-box design to access single shielded cup/clip electrodes with touch proof connector (1.5mm).
4. Build-in impedance testing function and automatic calibration (both sine wave and square wave);
5. Fully battery power Operated. Offering the highest signal quality. This EEG/ERP/PSG System is designed to eliminate virtually all noise from the mains power by running 100% on batteries.
6. It have different configuration for choice:
24/48 channels unipolar EEG;
Additional 12 channels Bipolar EEG;
Additional 12Channel PSG: EOG, EMG, ECG, SpO2, air flow, thoracic and abdominal respiration, Snore.
Additional ERP examination with Acoustic&Visual stimulator. It has three stimulation functions: Sound, light and electricity, and it configure with special earphone and VEP monitor.
Synchronized video monitoring which is software control zoom/tilt and infra-red lamp to support night monitoring
