It is possible to validate the signals coming from any DA100A/B/ or C amplifier by using a CBLCAL* Calibration Cable. The cable connects to the front of the amplifier and the UIM100C Analog Output 0 or 1, or to a known signal source in the ± 10 V range. Create a stimulus signal using AcqKnowledge and monitor the output of the amplifier that the CBLCAL is connected to. The CBLCAL will attenuate the output signal (1/1,000), and the amplifier will amplify the signal by the gain setting.
For example, if the stimulus signal is 1 V and the gain setting is 1,000, the corresponding signal from the amplifier should be 1 V. The signal can be used for amplifier validation and signal calibration.
If the signal is significantly different than the source signal level, contact BIOPAC for further assistance.
* Note: Most other amplifiers require CBLCALC, not CBLCAL.
BIOPAC will show you how physiological data is seamlessly synchronized with eye tracking and stimulus presentation in one integrated solution. The talk will focus on optimizing setup, highlighting the benefits of a fully-integrated solution, and how to extract eye tracking and physiology metrics from key points, such as the cumulative average skin conductance level while a participant is focused on areas of interest.
What you will learn: • Hardware setup • Stimulus presentation creation • Setting up Areas of Interest (AOI) • Recording participant data • Analysis and reporting
BIOPAC provides software and hardware that allows research teams to study stimulus presentation data. Here are a few notable studies using BIOPAC equipment for research on stimuli’s effects using ECG and SCL data.
