When you purchase a copy of AcqKnowledge 4 or a Research System that includes AcqKnowledge 4 you will receive one License Key (iLok USB). If you have purchased a system with additional licensed features such as Scripting, NDT, or Pressure-Volume Loop Analysis, these licenses will be pre-loaded on the License Key.
Immediately after receiving your software, the License Key should be registered on the BIOPAC website under Support>Product Registration. Registering your Software and License Key allows you to be eligible for the discounted License Key replacement program.
If you lose your key, contact BIOPAC Support. The Support Department will verify your License Key serial number via the product registration page and your customer account.
For standard key/license configurations (i.e., combinations sold on this site):
The first time you lose your registered key—a replacement License Key will be issued for a deeply discounted price.
If you lose your key multiple times, the cost of a replacement key will rise—contact BIOPAC support for details.
For custom keys, users must upgrade to AcqKnowledge 5; effective November 2016 BIOPAC no longer uses/creates iLok keys except for B-Alert and Stellar systems.
To add additional user licenses to your AcqKnowledge Software, please see the Site License Program. Options are available to add one additional user, four additional users, eight additional users, etc.
Please contact firstname.lastname@example.org with any additional questions regarding key registration and replacement.
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 […]
