Jitter Free USB
When sending event markers via USB, StimTracker delivers them with jitter free precision when used with SuperLab 6 or with our open source Python or C++ libraries. Delay is guaranteed to be 2 milliseconds exactly, every time. Other software packages may not deliver jitter free performance; for instance, E-Prime E-Basic code precision is 5 to 8 ms.
The combination of powerful 32-bit microprocessors and our software makes possible the following features:
To send, say, a 10ms long event marker with other I/O devices, an app needs to raise the output line, wait 10ms, then lower the line. With StimTracker, all the software needs to do is send a command and resume its work while microprocessors take care of delivering the pulse.
A truly unique feature: tell StimTracker when to send pulses at a later time, e.g. to mark emotional points during a movie presentation.
Use StimTracker as a signal generator on an output line or as a more complex pattern generator.
Use the AcqKnowledge Digital inputs to stim events tool to automatically score and label digital event marks from the SuperLab presentation. The digital channels are interpreted as a binary number. Each stimulus event placed into the graph has the corresponding number included with its label. This allows further analysis to distinguish between different types of stimulus events for automated event related analysis.
