UnInterrupted Variable Pulse Generator (unVPG)
Published: 7 October 2014
A small, inexpensive battery powered unit uses a microprocessor to allow users to control the pulse frequency and to change quickly and easily between different pulse frequency. The unit provides a second output with a delay that can be determined by the operator. Suitable for physiological and neuroscience applications.
Pulse generators are used in many physiological experiments to drive stimulators or other interventions repetitively and to trigger data capture at precise intervals before or after the stimulus. Current stand-alone devices set stimulation frequency using an analogue dial, which provides inexact interpulse intervals. Simpler digital timers provide precise intervals but don't allow smooth transitions between different pulse frequencies. Programmable stimulators based on computers are precise and flexible but are relatively bulky.
