When the amplified signal for any given channel exceeds the range -10 to +10 volts, the signal will rail. You will see a straight line at -10 or + 10 volts (more likely the reading will be close 9.99 volts). The MP system is designed to work only in the range -10 to +10 volts. The signal could rail for several reasons (which are not exclusive):
The signal is too strong for the current gain setting on the amplifier. Try reducing the gain setting.
You are recording in DC mode when you should be recording in AC mode. If this is the case, make sure DC is off and a switch is set to 0.05Hz HP or 0.5Hz HP.
Your amplifier baseline (offset) is not adjusted properly. Please consult with application note 110 for details on how to make the required adjustments.
Eyes are the window to the soul and, more importantly, the brain. Psychophysiology, neuroscience, and consumer neuroscience researchers use eye tracking technology to understand emotion, behavior, subject response, decision-making, and human performance—and to help improve products and services. But not everyone knows where to start or how and why to use this important technology. A panel of eye tracking experts will present typical use cases and the latest eye tracking technology.
Join this online presentation with Q&A to learn the fundamentals of eye tracking!
Recent physiological studies feature BIOPAC’s Wireless BioNomadix Data Recorders Using Metronomes and Rhythmic stimulation to help people with Parkinson’s disease walk For those living with Parkinson’s disease, even simple tasks can take too long to accomplish properly, such as crossing a room or picking up an object. In this study, participants with diagnosed cases of […]
