g.TRIGbox: Specs & Features
g.tec's multimodal trigger system. Use various trigger sources to detect and record events reliably.
g.TRIGbox - gtec's Multimodal Trigger Conditioner Box
The g.TRIGbox is a device to generate trigger pulses from various sensors or input signals. Input and output lines are isolated from each other. The trigger outputs can be connected to digital or analog inputs of a data acquisition system (such as g.USBamp, g.HIamp, g.Nautilus or g.MOBIlab+).
Thus, g.TRIGbox provides exact detection and recording of almost any type of stimulation in your experimental paradigms. Its wide range of possible input signals and sensors allows the use of various trigger sources such as sound card outputs, microphones, piezoelectric or inductive sensors, response buttons, various logic signals (TTL, C-MOS, ...) provided by external stimulators, visual markers from the computer monitor, LED indicators, flash lamps or slide projectors. The threshold levels are adjustable separately for each channel. 4 LEDs indicate the proper detection for each channel.
- Simply use PowerPoint for stimulus/paradigm setup and presentation
- > 4 kV isolation between trigger inputs and outputs
- Use various trigger sources from visual, auditory, electrical or tactile stimulators
- Connect to a data acquisition system, g.MOBIlab+, g.HIamp, g.Nautilus or g.USBamp
- Compatible with many other user-specific systems
- Use one encoded trigger channel for up to 16 different experimental conditions

The output signals of the g.TRIGbox are rectangular pulses with a minimum length of 20 ms assuring a reliable recording of all events even for low sampling frequencies. An additional analog encoded trigger output enables the recording of up to 16 different experimental conditions. In this case, the output signal displays 16 different output voltage levels to be decoded during data analysis (e.g. with g.BSanalyze).
The optical sensors which can be fixed at the computer screen easily allow the quick and comfortable generation of experimental paradigms and stimulation patterns for psychophysiological studies. No special stimulation software is needed anymore. A simple and easy way is provided via PowerPoint for stimulus presentation.
