EEG-1142 amplifier.


BRAINBOX® EEG-1142 Amplifier.
This “smallest of the world” EEG amplifier measures only 9 x 10 x 1 cm and weighs less than 100 gram. Indeed very small, but with excellent performance! The Digital FIR filters have a linear phase response and attenuate -40dB (!)at ½ Sample Rate for very low aliasing errors in your analysis results. The very small size of the amplifier is convenient for ambulatory recording. The EEG-1142 has full electrode impedance check circuits and in Calibration mode the Calibration Voltage is applied to the real input of the amplifiers for a real overall test of the amplifier. Active ground G1/G2 suppresses 50/60 Hz. in noisy environments and SpO2 and Event button are supported in this amplifier. Additionally to the 32 EEG channels, there are 8 DC channels for recording the output of special sensors. More EEG-1142 amplifiers could be used for multiple patient recording with one interface and one PC.
