Biosemi data collection problems

Hello everyone,

I am using a Biosemi system with the SigfriedSigProc filtering application for real-time brain mapping. However, about 20 seconds into a session this will happen. Another picture a few seconds later.

I have SourceFilter included in the Biosemi application and I am applying a high pass filter at 0.1 Hz and a low pass filter at 40 Hz.

Has anyone had this type of problem in the past? If so, how did you solve it?

Thank you.
