Quest HD EEG & ERP System
a Portable, wireless full featured EEG/ERP and EMG Lab
Research can take you many places. The 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 of up to 256 EEG/ERP channels and simultaneous EMG recording, with 24-bit resolution and a 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. 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.
Weighing a mere 700 grams, the Quest HD maximizes mobility by utilizing wireless data transmission and internal data storage, as well as an internal battery to eliminate being tethered to an outlet as well as the possibility of grounding issues. 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.
