Initially, when using other solutions for EEG signal acquisition, we encountered a severe interference problem during EMC immunity tests (EFT, surge) of EEG acquisition. Because IEC 60601-2-26:2012 requires in section 202.6.2.4.1 that the EEG waveform should continue to be displayed during EFT testing, and our electrode wires are very long (1-1.5m), we cannot solve this EMC immunity problem. Therefore, I am now considering using the ADS1299 solution for EEG acquisition. I would like to ask how to solve the problem of EEG signal interference during EFT, surge, and other tests using the ADS1299 solution, while meeting the EMC requirements of IEC 60601-2-26:2012 and IEC 60601-1-2:2007?.
