Amplitude-frequency characteristic zz error is: +< br/> Power spectrum frequency: the error does not exceed
Power spectrum amplitude: the error does not exceed
Noise level: no more than r (peak-to-peak)
Common mode rejection ratio: each channel is not less than< br/> Polarization voltage resistance: the added DC polarization voltage deviation is not bad
EEG topography function
It has the function of simultaneously collecting conductive EEG signals and drawing EEG topography voltage and frequency measurements. Three-dimensional topographic map display function, case database classification management function, multiple event description functions, display function of compressed spectral array, histogram, curve chart, percentage chart and spike topography map, data storage and recall function, graphic data printing function.
