1. Standard 32 channels of EEG. 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).
2. Adopt bioelectricity amplifier for distilling brainwave, continuous record time can be up
to 24 hours, integrated full-automatic calibration system.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. Integrative image and character report, report can be edited in mode and switched to
Word document.
13. Case files can be transformed into EDF and BDF data format, convenient for data
exchange, academic exchange and further analysis.
14. System parameters and display modes can be set as required, which meets different user’s
requirements.
15. Add marks and annotations to the waveform designated, which can rapidly find the
waveform in that time by marks.
16. Optional video function: USB camera is easy to install, convenient to use and exact to
record. With flexible playback function, which can browse the waveform of any time
along with the corresponding isochronous collected image.
17. SpO2 function which can view SpO2 value, pulse rate and SpO2 trend graph is optional. Accessories
