NeXus Trigger and synchronization Interface (NTI)

The NeXus Trigger Interface (NTI) is used to accurately synchronize the physiological parameters being recorded by the NeXus device with external stimuli (triggers) generated by computer running e.g. E-prime/Presentations or external devices like Eye-trackers. It can be used for registering stimuli in event related potentials (ERP) or evoked potentials (EP) experiments, also in combination with E-prime or presentations.

Features

The NTI measures all of its inputs with 2048 samples/second, which comes to an accuracy of less than 1 ms.

Synchronize external stimuli by sending markers to the NTI over a RS232 Serial cable, the light sensor, microphone or audio cable.

Systems

The NTI can be used with the NeXus-10 MKII and NeXus-32F.
