Black Box ToolKit version 2 software specifications



The BBTK version 2 comes complete with a redesigned and fully integrated control and analysis application written in the Microsoft .NET 4 framework for the Windows Presentation Foundation (WPF). It supports Microsoft Windows XP SP3, Vista SP2, Windows 7 SP1, Windows 8/8.1 and Windows 10 Technical Preview natively. It also supports VMWare/Parallels on Mac OS X and Linux so long as a virtual serial/COM port can be used.


























Works with the BBTK online "Proof" repository where you can upload your self-validation timing reports and link to them via a DOI. Great for self-certification when you publish your research! Be ahead of the curve.




Digital Stimulus Capture And Response (DSCAR) module timing characteristics

 Various validation timing tests have been carried out at all stages of development. Initially these have focused on the Digital Stimulus Capture And Response (DSCAR) module of the BBTK and associated ARM firmware. Timing measures presented are round trip times. That is, the time taken to detect a stimulus and generate a response to it. It should be noted that timings are affected by how appropriately sensor activation thresholds are set and the quality of the equipment presenting the stimulus.
