Presentation, synchronization & response timing validation and event marking

Product/Features

BBTK v2

mBBTK v2

USB TTL Module


Main function
Presentation, synchronization & response timing validation.
Complex real time timestamping and TTL event marking/TTL triggers.
Basic event marking.
Example usage Independently check the onsets and durations of stimulus images, sounds or event marks against responses. Also lets you tune your experiment generators accuracy in a particular study by automatically simulating a human participant that is millisecond accurate. This enables you to modify onsets, delays and RTs so that they are accurate in the real world. Timing critical independent TTL event marking of stimulus images, sounds, TTL inputs or response pad button presses on EEG machines or eye trackers. Create TTL triggers quickly, easily and reliably in EEG, fMRI or any cognitive paradigm. Acts as a USB parallel port replacement to allow basic TTL event marking/TTL triggers from any experiment generator that supports a serial port.
