Features
Integrate collection magnification, filters and A/D transformation of EEG signal into this product which adopts SMD technology, adjust amplitude automatically, and with good anti-jamming ability.
24-hour carrying for recording, and user can move normally, which is convenient for monitoring, capturing the concealed and moment EEG pathological waveform.
Bluetooth sync collection, real-time data uploading and waveform monitoring.(optional).
Waveform playback function, amplitude and playback speed are adjustable, montages can be set freely(such as monopolar, bipolar or user-defined montages).
Function of case contrasting, which can simultaneously view and contrast the waveforms of the two different cases or the same case waveform in different time.
System parameters can be set as required, which meets different user's requirements.
Clipping of the EEG waveform's segments, select any section of EEG waveform for analyzing and storing, and select several segments waveforms for automatically analyzing and distilling to different parameters.
Select any one or several times for power spectrum analysis, provide Compressed Spectral Array, and with many analysis charts, including kinds of BEAM, compressed spectrum graph and so on.
Spike-sharp wave auto-analysis system provides data statistics for spike wave, sharp wave, slow-wave, spike-sharp wave and spike-slow wave, etc. And trend chart for full pathologic wave, click trend chart to synchronously browse EEG.
Perfect case management function, provides many means for search and quick statistic information; convenient case export and import function, which is easy to store or communicate data.
Case files can be transformed into standard data format (EDF) in Europe, convenient for data exchange, academic exchange and further analysis.
Multifunctional digital filter systems provide different filter methods and window types, and user can freely set low-pass, high-pass, band pass and band stop filter.
Conveniently measure basic information of any EEG waveform designated; with partial enlarging window, to accurately measure EEG period, amplitude and frequency, and which can be adjusted according to personnel judgment.
Add marks and annotations to the waveform designated, and rapidly find the waveform in that time by marks.
Integrative image and character report, report mode can be edited, and several report templates are provided.
USB interface ensures fast and stable transmission speed.
