Description

Product highlights

• 4 versatile, low-noise channels enabling measurements of voltage, conductance, resistance, current and temperature signals.
• functions of individual channels are specified by a user (for example 4 x EEG, HEG + 2 x EEG or HRV + RESP + EMG + GSR etc.)
• additional channel for digital sensors, e.g. to mark events with a button,
• extension port for BVP (PPG), nIR HEG and pIR HEG sensors, also enabling new digital sensors to be added in the future,
• an EEG cap interface, with configurable connections between measurement channels and a 10-20 system cap, facilitating quick QEEG assessments and multi-site EEG training (Neurobit Optima+ 4 models),
• built-in test of electrode-skin impedances and input circuit continuity,
• independent reference inputs for each channel,
• connections of inputs to reference electrode(s) configured in software,
• 16-bit resolution of measurements,
• 1% accuracy of voltage measurements,
• output sample rate up to 2000 sps,
• oversampling (primary sampling rate up to 8000 sps),
• selectable frequency characteristics enable the signal delay to be minimized or the frequency bandwidth to be maximized,
• high immunity to electrical interferences,
• option of active shielding of sensor cables to reduce movement artifacts,
• configurable filter of mains power interferences (50/60 Hz or off),
• full galvanic isolation of the subject’s body,
• real-time transmission of data to a computer,
• interoperation with many biofeedback applications making possible flexible signal processing and visualization (also in real time), as well as storage in a computer,
• application programming interface (API),
• 2 AA battery powered (BLE version),
• power, data link and signal state lights,
• small size and weight,
• belt clip enables the device in BLE version to be worn (USB version has got legs),
• remote updates of program in the device (firmware),
• standard Touch Protected 1.5mm measurement connectors (DIN 42802),
• compatibility with most types of routinely used electrodes (AgAgCl, Ag, Au, Sn etc.) having TP connectors, as well as variuous electrode montage solutions,
• made in the European Union,
• CE mark.

Neurobit Optima+ works with several software applications enabling flexible data processing and storage, audio and visual presentation of feedback signals (graphs, animations, DVD films, games etc.), for example:

• BT2 – Brain-Trainer’s Training and Assessment software
• BioExplorer – popular, feature-rich biofeedback software with visual designs of data processing and presentation.
• Mind-Body Training Tools – multimodal biofeedback package for peak performance training
• BioEra – advanced application for bio-signal processing
  Quick start with BioEra
• BrainBay – free biofeedback software for personal use
• Neurobit Recorder – freeware for physiological signal recording in EDF (European Data Format) and text files, which can be imported in many applications, such as EEGLAB for Matlab or Excel

Warranty

Neurobit Optima+ is sold with:

• 2-year warranty as a standard. Extension is also possible.
