ActiView is a comprehensive acquisition tool that showcases all ActiveTwo channels on a screen while saving the data in .BDF format to a network disk. The user-friendly layout allows for a swift assessment of data quality. This software is capable of acquiring EEG, ECG, and EMG signals, in addition to data from various external sensors like the AnalogInputBox (AIB), digital triggers sourced from the USB2 receiver, and other devices linked to the AD-box, including respiration monitors, GSR sensors, temperature gauges, ergometers, and plethysmographs. Users can select from multiple reference options, apply filters, and utilize downsampling features. Thanks to our unique single-buffered approach, the acquisition process remains stable and dependable even during multitasking, as the DMA transfer to a large intermediate ring buffer guarantees that no data is lost. ActiView is an open-source program developed in LabVIEW, making it an exceptionally flexible resource for researchers who wish to modify and enhance the software to suit their specific needs. Its adaptability and robust features position it as an invaluable asset in experimental setups.
