1.Standard 24 leads of EEG. Method of 10/20 electrodes placement under the international standard system, can change leads ways while real-time playing or replaying. Supporting sorts of lead mode, such as Al, A2, A1+A2, A1←→A2, BN, CZ, user-defined, and so on.

2. Using bioelectricity amplifier brainwave, consecutive record time can be up to 24 hours, integrated automatic calibration system.

3.Powerful playback function: It is adjustable for the amplitude and replaying rate. The special subdividing timeline divides the waveform in one second into 5 parts and easy for the doctors to look over the waveform

4.Multifunctional digital filter system can be set freely and provides many filtering methods.

5.EEG signal clipping function, clipping any section of EEG wave to analyze and store, clipping multisection waves to perform multiparameter analysis and pick up automatically.

6.Electronic frequency ruler, convenient to measure the basic information of any appointed EEG waves. Sectional enlarging window, which can be adjusted by yourself, is provided to increase the accuracy of EEG period /amplitude /frequency measurement.

7.Mark event (opening eyes, closing eyes, and flashing) EEG with different colors, and name the user-defined event. The color of background and waveform occurred by the different events is adjustable. It is able to depend on the event's name to locate speedily the waveform of the corresponding time.

8.Powerful automatic analysis function can carry through the power spectrum analysis and pathologic wave detection for the appointed waveform. Sorts of the graph can be displayed on 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 a USB interface to transmit data that 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

10.Multifunctional flashlight of USB interface and frequency can be controlled manually or automatically. A flashlight stimulus scheme can be set and performed in the process of collection.

11.Perfect case management, multimethod 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.

12.The report of picture and character integration, can be edited in mode and changed into Word.

13.The case can be transformed into the EDF data format, which is convenient for data interchange, academic exchanges, and further analysis.

14.System setup function, multifunction, such as display mode, system parameters, etc., can be set to meet the users' special need.

15.Mark positioning function: add the mark and note for the waveform of the appointed time, and locate speedily the waveform at the mark time.

16.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.

17.SpO2 function is optional.
