SKU: 1705 Category:


Pulsar is a small and easy-to-use device for presenting auditory tones and clicks. Pulsar produces triggers with each auditory stimulus and hence, can be used in combination with an EEG system for recording responses like AEP, P300, ABR and more.

The timing and presentation of the audio is completely controlled by fast microprocessors. This guarantees exact synchronization of the onset of the audio and the TTL trigger in addition to reproducible tones and clicks.

An intuitive menu makes it convenient to select a paradigm and to configure its parameters.

Supported paradigms for:
– Tones: Single Tones, Oddball, Paired Tones
– Clicks: Single Click, Paired Clicks
