DATAPixx3

Fiber optic video I/O Hub

The DATAPixx3 VideoBahn architecture allows all of your visual and auditory stimulation, and all of your button box, eye tracking, digital, analog, and audio data, to be synchronized to a single clock with microsecond precision. This unique fiber-optic integration can help your group study more subtle effects in brain activity. VideoBahn, the new fast road to superior data
