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.
