DESCRIPTION

The BioSemi ActiveTwo system is equipped with up to 280 channels, a DC amplifier and 24-bit resolution, setting world-leading standards for multi-channel, high resolution, biopotential measurement systems for research applications. The ActiveTwo system is a further development of the successful ActiveOne system, which was the first commercially available system with active electrodes. Advances in technology have allowed BioSemi to significantly increase the number of channels, digital resolution, input range, and sample rate, without any increase in size, power consumption or costs. The second-generation active electrodes are smaller in size with less cable weight, while offering even better specs in terms of low-frequency noise and input impedance. The BioSemi ActiveTwo system upholds superiority over competing designs.

System Features

Up to 256+8+2 channels in a single box.

Second generation active electrode: smaller size, less weight and strain-relief.

Flexible coloured electrode labelling system.

24-bit ADC per channel, unsurpassed S/N ratio and linearity.

Improved digital resolution, LSB value is 31nV.

Full DC operation, the largest input range in the industry (524mVpp).

User-selectable sample rate, high sampling available.

Full range of auxiliary sensor inputs available.

The BioSemi ActiveTwo system is fast to set up and does not require skin preparation for achieving reliable measurement. The ActiveTwo system is compatible with MEG/MCG and suitable for EEG, ECG as well as EMG measurements, allowing graphical programming (LabVIEW) on PC and Mac. The ActiveTwo is battery powered with high-speed fibre optic data transfer, which makes the subject fully optically and galvanically isolated from any mains. The BioSemi ActiveTwo system is specifically designed to be used in research applications only. The system benefits from freely configurable hardware and completely open-source software.
