Functional Description

This setup requires the following components:

  • #:
  • #:


is a clinical monitoring system capable of acquiring EEG or ECoG signals from up to 256 channels. Paired with the QI-123A LAN converter box, this system can provide a research data stream in addition to the clinical data stream. The research data stream can be sampled at up to 2kHz for 256 channels, 5kHz for 128 channels or 10kHz for 64 channels. [edit]

  • Input range: ±3.2 mV or ±12.8 mV (selectable)
  • Effective resolution: 16 bit (97.65 nV/LSB) or 16 bit (390.62 nV/LSB) (selectable)
  • Input impedance: 200 MΩ
  • Sampling Rates: 100Hz, 200Hz, 500Hz, 1000Hz, 2000Hz, 5000Hz, 10000Hz

Parameters

  • SourceCh total number of channels to be acquired from the source module or auto for all channels (256 channels)
  • SampleBlockSize number of samples acquired in each block or auto for default setting (1/10th of sampling rate)
  • SampleRate determines the rate at which the device samples data.
  • ChannelNames is a convenience parameter. Name channels here and they can be referenced by these names later.
  • SourceChOffset auto for default settings (0 for each channel).
  • SourceChGain auto for default settings (1 for each channel).
  • SourceChList list of channels that should be acquired or auto for all channels
  • SourceBufferSize
