Design Features

  • Amplifier provides 45 leads (32 unipolar leads, 10 bipolar leads, 3 additional leads), integrated pulse oximeter and event button input
  • 24-bit A/D data conversion
  • DC Acquisition Records
  • Can be used in conjunction with Neuroscan STIM software system (or other stimulation software) to implement complex ERP experiments
  • Easy to install, simple and friendly
  • Grael connects to the computer via POE Ethernet
  • No special interface card or special power supply is required, it supplies power and transmits data via POE Ethernet
  • Integrated pulse oximeter and event button input

Working mode

Grael amplifiers can be optionally configured with a special wireless transmission module to enable wireless transmission between the amplifier and the computer. Special wireless transmission modules are also available to support multiple Grael amplifiers in parallel for higher lead count EEG acquisition devices.
