Nerve and Muscle Stimulator
S48 SQUARE PULSE STIMULATOR

Single, Repetitive and Train Outputs. TTL Synchronization, External Analog Control of Rate

The S48 is a general purpose stimulator intended for nerve and muscle stimulation procedures with applications extending from single cell to entire muscle stimulation. It can be set to deliver single, repetitive, twin pulses, trains of pulses and trains of twin pulses from its single output.

Features include computer compatibility and flexibility of synchronization circuits. The synchronous inputs and outputs are TTL, 5 volt, PC compatible. A rear DB25S connector permits external analog control of the timing circuits.

The constant voltage output is a positive, nonisolated voltage and must be used with an optional Stimulus Isolation Unit for applications requiring isolation and/or constant current.
