Acqknowledge 4.1

Biopac Research Systems

ACQ 4.0
AcqKnowledge is an interactive, intuitive program that lets you instantly view, measure, analyze, and transform data. Perform complex data acquisition, stimulation, triggering and analyses using simple pull-down menus and dialogs—no need to learn a programming language or new protocol. Online analysis settings, filters, and transformations provide real-time feedback, or you can choose from a wide variety of off-line analysis tools. Multiple display options are available during and after acquisition—just click on an icon to flip between Chart, Scope, X/Y, Overlapped segments, Histogram, or FFT. The software also includes quality presentation capabilities.

AcqKnowledge 4 runs on AcqKnowledge data acquisition and analysis software for Windows OSWindows OS; click for Compatibility Table.
