Stimulator Module

Description

The STM100C module provides pulse and waveform stimulus outputs for nerve conduction, evoked response (e.g., ABR studies audio stimulus-response (e.g., startle response) and somatosensory response studies. Stimulus duration, repetition, onset and amplitude are completely programmable. For interactive changes during recording, stimulus amplitude levels can also be controlled manually. Overload and pulse stimulus indicators are positioned on the module’s front panel for easy viewing. The 50 Ohm output port can simultaneously output a trigger or analog signal to piezo transducers, recorders, oscilloscopes, meters, etc. The External Stimulus output port on the STM100C can be used to drive headphones or tubephones directly.

In addition to providing computer control of stimulus waveforms, the STM100C can also buffer signals from any Biopotential or Transducer module, which has its output directed to the STM100C input during recording.

The Stimulator setup in AcqKnowledge provides easy-to-modify single-, double- or multiple-pulse sequence outputs of any polarity. The Stimulator setup screen also provides standard sine, triangular and square wave outputs for other kinds of physiological tests. Create an arbitrary waveform by modifying an existing wave or reading in a sequence of user-specified numbers (text file).
