Features
Method of 10/20 electrodes placement under international standard system, leads can be changed during replaying. Support different types of combined leads during sampling.
Adopt bioelectricity amplifier for distilling brainwave, continuous recording time can be up to 24 hours, integrated full-automatic calibration system.
Powerful playback function: amplitude and display speed are adjustable. The special subdividing time line divides the waveform in one second into 5 parts, which is easy for doctors to look over the waveform.
Digital filter system can be set as required, providing different window types
EEG signal clipping function, analyze and store any section of EEG wave, and select several waveform segments for automatically analyzing and distilling to different parameters.
Electronic frequency ruler, convenient to measure the basic information of any appointed EEG waveform. With partial enlarging window, accurate measurement of EEG period, amplitude and frequency, which can be adjusted according to personnel judgment.
