Dear support,
I'm currently performing a combined EEG/EMG experiment (64 EEG channels + 8 externals). I'm also using Ergo1 and Ergo 2 channels to record response force signal.
Here is the problem:
When I plug the EEG into the amplifier, the response force signal (Ergo1 and 2) disappears. Note that signal is normal on the 64 EEG channels and the 8 externals. However, when the EEG is not plugged, the response force signal is normal. Any idea about the problem?
Cheers,
Mathieu
Recording EEG + 8 external electrodes puts ergo signal to 0!

Re: Recording EEG + 8 external electrodes puts ergo signal t
Are the force sensors connected to anything else than the ERGO input on the AD-box ?
How is power supplied to the force sensors (battery or from ERGO connectors) ?
Do the ERGOs work with the electrodes in water ?
Does is make a difference whether the subject (with EEG working) touches the force sensors ?
Please sent a diagram of the setup to info@biosemi.com
Please make a BDF file of few seconds showing the moment that the electrodes are plugged into the AD-box.
