Function Features
Standard 24 channels(19 channels of EEG + 5 channels of multi-parameter). Method of 10/20 electrodes placement under international standard system, montages can be changed during collecting or replaying(such as monopolar, bipolar or user-defined montages). Support different inactive electrode during collecting(such as A1, A2, AA, AV, Bn, Cz).
Adopt bioelectricity amplifier for distilling brainwave, continuous record time can be up to 24 hours, integrated full-automatic calibration system.
Powerful playback function: Two playback modes(continuous and rolling) are optional, 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.
Multifunctional digital filter system provide different filter methods and window types, and user can freely set low-pass, high-pass, band pass and band stop filter.
EEG signal clipping function, analyze and store any section of EEG wave, and select several segments waveforms for automatically analyzing and distilling to different parameters.
Electronic frequency ruler, convenient to measure the basic information of any appointed EEG waveforms. With partial enlarging window, to accurately measure EEG period, amplitude and frequency, and which can be adjusted according to personnel judgment.
Mark EEG wave under the events of opening eyes, closing eyes and flashing with different colors, and user-defined events can be added, waveform color for evoked event can also be set freely, ensures that the waveform in corresponding time can be rapidly found by event name during case playback.
Powerful automatic analysis function, can carry through the power spectrum analysis and pathologic wave detection for appointed waveform. Many graphs can be displayed in the same screen, including kinds of BEAM, numerical BEAM, compressed spectrum graph, trend graph, and so on.
Professional isolation transformer, dual power supply isolation system and optoelectronic data transmission to ensure security. Use USB interface to transmit data which just need to be inserted.
Multifunctional flash stimulator of USB interface, and frequency can be controlled manually or automatically. A flash stimulation scheme can be set and performed in the process of collection.
Perfect case management function, provides many means for research and quick statistic information; Convenient case export and import function, and stores with CD-RW disk, which is easy for data research.
Integrative image and character report, report can be edited in mode and switched to Word document.
Case files can be transformed into EDF and BDF data format, convenient for data exchange, academic exchange and further analysis.
System parameters and display modes can be set as required, which meets different user's requirements.
Add marks and annotations to the waveform designated, which can rapidly find the waveform in that time by marks.
Optional: Video function & SpO2 function.
