The Model 2200 Analog Stimulus Isolator is designed for a wide variety of applications. It

provides opto-electrical isolation for stimuli generated by a wide range of signal sources. The

signal is DC-coupled, and can take on any waveshape within its wide bandwidth. The input

signal voltage, scaled according to the Range switch setting, can result in an output as large

as 100V (or ±50V), and ±5mA. The output signal can be turned on and off by a digital Control

Gate. If for any reason the instrument cannot follow the input signal, an Error indicator lights.

The isolated output section is battery-powered and optically-coupled to the input section, for

the ultimate in clean isolation. The battery is adequate to provide full function for at least 8

hours of continuous use. An internal battery tester is provided. A charger is supplied, and an

oven-night charge cycle is all that is required to ready the 2200 for another day's use. It is

easy to swap a freshly charged pair of batteries if extended use is necessary.

There are several features to make this instrument highly useful in a computer-driven

environment via the Control port. The instrument is well suited to accepting analog signals

generated under computer control, isolating these signals from the noisy electrical

environment associated with a computer, and coupling them to biological tissue. The error

detection circuitry generates a TTL-level Control Error signal if the instrument is unable to

deliver the required signal. It is also possible to detect a low battery condition at any time,

without altering the isolation or interrupting an ongoing experiment.

The instrument is not intended for clinical measurements using human subjects. A-M

Systems, Inc. does not assume responsibility for injury or damage due to the misuse of

this instrument.

WARNING the Model 2200 can produce potentially dangerous voltages (up to 100V) at

the output. The isolated output is not connected internally to safety (earth) ground in any

way. Some part of the external circuit should be connected to safety ground. Use

caution in handling any wires, connectors, or electrodes which may be directly or
