-EEG Testing


The EEG CMRR tester combining accuracy,convenience and test automation all together. Compliant with IEC80601-2-26:2019 and applicable for R&D, compliance and production run testing

Ordering information
  • Designed for EEG CMRR and system noise testing.
  • Double shielding structure to avoid internal and external noise interference.
  • Built-in calibrated sine wave generator and Vc voltage measuring circuit to assure output accuracy level.
  • Touch panel allows user to select test standards and adjust test parameters in standalone usage. PC software mode is available when connecting CMRR 3.0E to PC via USB.
  • CMRR Assistant software pack to simplify the standard into adjustable parameters and selectable options.
  • Software Development Kit (SDK) allows user to develop customized or automated test software with less efforts.
