Model g.HIamp - Biosignal Amplifier With 256 Channels for Invasive and Non-Invasive Measurements
g.HIamp is a high-performance biosignal amplifier with 256 channels for invasive and non-invasive measurements of the brain that is FDA cleared and CE approved. g.HIamp provides excellent signal resolution and a wide input sensitivity to record EEG, ECoG, ECG, EMG, and EOG without any saturation. External body sensors can also be connected. Internally, signal processing is performed with the fastest floating-point DSP and a sophisticated real-time Kernel. The amplifier relies on a very high oversampling to reduce the noise as much as possible by averaging samples.
256 channels can be analyzed in real-time with g.HIsys Highspeed Processing for Simulink software. This provides faster and more accurate control of BCI systems that use Common Spatial Patterns (CSP). g.HIamp is equipped with 16 digital trigger channels and a HOLD input for artifact suppression (e.g. during electrical or magnetic stimulation).
g.HIamp EEG amplifier has 80, 144 or 256 channels and can be used with passive or active EEG, ECoG, ECG, EMG and EOG electrodes. The difference between these options is just the electrode connector box. Each block of 64 channels is connected via a multi-pole medical safety connector to the electrode box. For ECoG grids and strips, special interface connectors are available too.
