Elec. ref. for one biosemi system multiple participants

Chanel · Post by **Chanel** » Wed Jan 16, 2008 9:29 am

Hello,

we plan to record online two participant with one biosemi system. One paticipant using EMG recordings and the other using EEG recording. The main question we have is the question of references.

Is it possible to use both references (EEG CMS&DRL and front panel CMS&DRL) at the same time for different participant ?

Otherwise is there a way to have a common reference for both participants ?

Thanks in advance.

It is not possible to measure two subjects simultaneously with only one AD-box. However, the ActiveTwo system offers the unique option to measure up to four subjects simultaneously with daisy-changed AD-boxes (each subject has its own AD-box). Information is found on http://www.biosemi.com/new.htm, scroll down to 26 September 2005.
