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.
Electrodermal Activity (EDA) is an objective index for understanding emotional states. Researchers measure EDA to gain insights on psychological or physiological response, leading them down the path of scientific discovery. Because EDA is so important to research, BIOPAC has created tools to optimize event-related EDA analysis. Topics include: how to identify skin conductance responses, convert stim events from E-Prime SuperLab, Presentation, Vizard, etc., into AcqKnowledge events that can used for analysis, and score skin conductance responses using the AcqKnowledge automated EDA analysis tool.
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
