The SIU-202 is ideal for providing stimulation when stimulus artifacts must be kept to a minimum, such as in nerve or muscle research.
This instrument features optical isolation at the input and a battery powered constant current delivery circuit. Timing pulses can be controlled by any device capable of generating a TTL level positive pulse (eg, a computer with data acquisition).
On the instrument rear panel are two TTL inputs; one comprising a standard BNC, the other using an optional fiber-optic converter box. The fiber-optic eliminates all ground connections to the SIU-202.
The SIU-202 output amplitude is set via a range-mode switch, used in conjunction with a ten-turn potentiometer to select what percentage of the chosen range is applied.
The constant current output has 100 V compliance with an LED over-voltage indicator. The compliance voltage may also be set to a lower value by simply reducing the number of 9 volt batteries installed within the instrument. A low battery light provides advanced notice of battery status, and ultra low power electronics provide up to 250 hours of operation for the 2 mA output setting.
Output connection is made via panel-mounted 5-way binding posts, (ie, banana jacks).
