The ActiveTwo system is delivered with free open-source acquisition software called ActiView. ActiView is a complete acquisition program designed to display all ActiveTwo channels on screen and save all the data to a disk in .BDF format. The layout is designed to give the user a quick and simple check of the quality of the data. ActiView can be used for acquisition of EEG / ECG / EMG signals, as well as for data coming from additional sensors such as the Analog Input Box, digital triggers from the USB 2.0 receiver and extra sensors connected to the A/D Interface Box (galvanic skin response, respiration, temperature, plethysmograph / pulse or other signal sources). Several reference selections, filtering and down-sampling options are provided. ActiView's proprietary single-buffered acquisition method makes data acquisition completely stable and reliable, even during multitasking on the Windows platform. DMA transfer to a large, intermediate ring-buffer guarantees no data loss.
The latest version, complete with source code can always be downloaded from the ActiView download page. ActiView is constantly changed and improved by incorporating suggestions and LabVIEW code examples from customers. The basic acquisition program can be expanded with modules on client specification. Our large knowledge of LabVIEW, enables quick and cost-effective development of these additional modules tailored to your application.
The open-source nature of ActiView makes it a particularly versatile tool for scientists who want to edit and expand the software according to their own ideas. Thanks to the flexible setup of LabVIEW, it is easy for a user with LabVIEW to modify the standard program for specific applications. This way you get a virtually "Custom made" acquisition program. You can make the front panel look exactly the way you want, arrange the channels the way you want -- make all the changes you always wanted in your acquisition software. The acquisition software is delivered complete with source code for users with a LabVIEW license or as stand-alone executable for users without a LabVIEW license.
Several modules are available for online analysis of the measured physiological data. For example modules for skin conductance, FFT, respiration and force analysis are readily available. With a LabVIEW development license, you can make your own on-line analysis modules to extend the functionality of the standard software.
LabVIEW is National Instruments' graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. With LabVIEW, engineers and scientists interface with real-world signals, analyze data for meaningful information, and share results and applications. Regardless of experience, LabVIEW makes development fast and easy for all users.
