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 is officially released for BIOPAC for Windows OSWindows Vista OS and an MP150 System. Testing was also performed with Windows XP; if AcqKnowledge 4 is installed on Windows XP, the user should not encounter any systemic problems related to the operating system. If you use an MP100, contact BIOPAC for compatible software.
