a Portable, wireless full featured EEG/ERP and EMG Lab
Research can take you many places. Quest HD ensures you are always prepared with a full featured multimodal EEG, ERP, and EMG solution that is just as capable inside the lab as it is on the road. The Quest HD allows for true high density recordings up to 512 channels, with 24-bit resolution and sampling rate of 7.5 ksps for the highest quality data. The Quest HD hardware is optimized for high quality data acquisition and real time streaming. Both EEG/ERP and EMG front ends are available to ensure maximum flexibility of the Quest HD. A fully featured Analog and Digital I/O ensures maximum flexibility for triggers and other devices.
Integrating with the Compass software allows for streamlined setup with automatic device and accessory recognition, and an array of useful features including real-time impedance measurement, integrated video tracking, and on-line ERP averaging. The Quest can also be controlled with well-established Matlab and Python APIs.
The Quest HD maximize mobility by utilizing wireless data transmission, and internal data storage as well as an integrated battery to eliminate being tethered to an outlet and remove the possibility of grounding issues. At merely 700 grams, Quest HD offers true mobility and untethered data acquisition with wireless data transmission, internal data storage, and an integrated battery for up to 512 channels. With on-board processing, and a bevy of trigger inputs and outputs, the Quest HD can be programmed for your unique paradigms with real-time syncing of external devices experimental control software.
