  • Record up to 16 EEG electrode locations (including reference)
    Up to 6 of the inputs can be used as differential pairs to monitor EEG or other physiological signals (e.g. ECG, EOG, respiration, etc.)
  • Continuous independent impedance checking to verify electrode connection integrity (can be disabled by user)
  • Electrode indicator LEDs assist with setup and troubleshooting

Physical Specifications

  • 10.4 cm x 12.1 cm x 4.4 cm (4.08" x 4.75" x 1.75") W x L x H
  • ~ 0.34 kg (0.75 lbs.)

Interface Cable

  • MDportTM - USB electrical interfacing using a medical grade keyed latching connector
  • Cable Length: 5 meters (16.4 feet)

Electrode Connections

  • 19 Touchproof (DIN 42-802) safety connections

Amplifier Inputs

  • Reference Input
  • Ground Input
  • 11 dedicated referential electrode inputs
  • 2 inputs configurable as separate referential inputs or 1 differential pair
  • 2 inputs configurable as referential inputs or 2 differential pairs (when used with the dedicated referential jack associated with each input)
  • Selectable continuous impedance testing when the EEG Amplifier is connected to the Monitoring System’s computer. Measurement is accurate to 1 kΩ or 20%, whichever is greater. (Note: The impedance test signal can be turned off by the user.)

  • Inter-channel Cross Talk: Less than 0.10% (-60db)
  • Gain: 33.5 ± 2.2 % before A/D converter
  • Bandwidth: 0.1 to 70 Hz to 70% response points (-3db)
  • Input Range: Up to 78 mV p-p full scale
  • A/D Conversion: 24 bit
  • Sampling Rate: 512 Hz
