1.nction Features
2.Standard 16 leads of EEG, compatible with 16 leads and 8 leads function.
Method of 10/20 electrodes placement under international standard system,
can change leads ways while replaying, and set electrode connection mode
at will.
3.Using bioelectricity amplifier brainwave, consecutive record time can be up
to 24 hours, integrated automatic calibration system.
4.Powerful playback function: It is adjustable for the amplitude and replaying
rate. The special subdividing time line divides the waveform in one second
into 5 parts and easy for the doctors to look over the waveform
5.Multifunctional digital filter system can be set freely and provides many
filtering methods.
6.EEG signal clipping function,clipping any a section of EEG wave to analyse
and store, clipping multi-section waves to perform multi-parameter analyse
and pick-up automatically.
Analyze and distill manifold parameters automatically. Choose and analyze
many segments of wave at the same time
7.Electronic frequency ruler, convenient to measure the basic information of
any appointed EEG waves. Sectional enlargine window, which can be
adjusted by yourself, is provided to increase the accuracy of EEG
period /amplitude /frequency measurement
8.Mark event (openning eyes, closing eyes and flashing) EEG with different
colors, and name the user-defined event. Color of background and
waveform occurred by different event is adjustable. It is able to depend on
the event's name to locate speedily the waveform of the corresponding time.
9.Powerful automatic analyse function, can carry through the power spectrum
analyse and pathologic wave detection for appointed waveform. Sorts of
graph can be displayed in the same screen, including kinds of BEAM,
numerical BEAM, compressed spectrum graph, trend graph, and so on.
10.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. Distance of digital signal
transmission is up to a maximum of 30 meters. Patients and doctors can be
operated in different rooms.
11. Multifunctional flashlight of USB interface, and frequency can be controled
manually or automatically. A flashlight stimulus scheme can be set and
12.performed in the process of collection.
Perfect case management, multi-method of information query and quick
statistics means, convenient case input and output function, supporting MO
or CD-RW store, which is easy for data research.
13.The report of picture and character integration, can be edited in mode and
changed into Word.
14.The case can be transfromed into the EDF data format, which is convenient
for the data interchange, academic exchanges and further analyse.
15.System setup function, multi-function, such as display mode, system
parameters, etc., can be set to meet the users' special need.
16.Mark positioning function: add the mark and note for the waveform of
appointed time, and locate speedily the waveform at the mark time.
17.Optional video function: USB CCD camera is easy to install, convenient to
use and exact to record. With agile playback function, it can be used to
replay the waveform of any time along with the corresponding isochronous
collected image.
