Grass Astro-Med stimulators model S88X Dual Output Square Pulse Stimulator

The S88X Stimulator applications extend from single cell to entire muscle stimulation. The two output channels can be operated independently or synchronized to produce complex paradigms. The outputs are non-isolated constant voltage monophasic, biphasic or twin pulses. Up to 9 sets of parameters can be saved for future use.

Features include：

• Computer Interface Control. Fully operational USB interface; write your own control application. Drivers, LabVIEW utility and demo C# program provided.
•  Remote control of existing parameters via PC with Windows-based host program
•  Customize and save up to nine paradigms
•  Digital panel controls – precise timing accuracy
•  Bright display simplifies setup
•  Independent or synchronous channel operation
•  Monophasic and biphasic modes
•  Dual train output
•  High current output facilitates field stimulation
•  Companion isolation units
•  Software replacement via USB cable
•  Interface with PolyVIEW16 physiological recording software
