Like-new condition. Output checked with oscilloscope.
The S88 is a dual channel, general purpose stimulator for nerve and muscle stimulation procedures. 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 positive pulses.

Train Duration: 1 msec to 10 sec (4 decades).
Rate (S1 and S2): 1/100 sec to 1000 PPS (5 decades).
Pulse Delay (S1 and S2): 10 §sec to 10 sec (6 decades).
Pulse Duration (S1 and S2): 10 §sec to 10 sec (6 decades).
Synchronous Outputs (TTL): S1, S2, S1 Delay, S2 Delay, Train; Front Panel: 10 §sec, 50 ohm; Rear Panel: 1 or 10 msec and Train End.
Synchronous Inputs (TTL): Train Duration, S1 Delay, S2 Delay; Trigger from rising or falling edge.
Rear Connector (DB25S): All SYNC INPUTS and OUTPUTS; External Analog Rate Control
Volts Out (S1 and S2): 10 mV to 150 volts (4 decades).
Peak Output Current: 450 mA.
Output Impedance: 250 ohm nominal on all voltage ranges; 25 ohm and 100 kohm on highest range.
