	::1. The '''Grass S88 Nerve / Muscle Stimulator''' is a dual output general purpose stimulator intended for nerve and muscle stimulation procedures. There are two output channels which can be operated independently or synchronized to produce complex paradigms. The outputs are non-isolated constant voltage positive pulses. Features include computer compatibility and flexibility of synchronization circuits: the synchronous inputs and outputs are TTL, 5 volts, PC compatible. A rear DB25S connector permits external analog control of the timing circuits. The Stimulus Isolation Unit (SIU) allows for applications requiring isolation and/or constant current. Grass S88 Electrical Nerve/Muscle Stimulator - Stimulation is triggered via TTL outputs from the S88 to the MEG Omega 3500 electronics.		::1.
