Standard Features

The 1902 is a versatile modular unit designed to work with CED’s Spike2 and Signal data acquisition systems. Developed for a broad range of applications, including EMG, EEG, ECG, ERG, and evoked responses, the 1902 accepts biological and instrumentation signals from a wide variety of sources including a wide variety of transducers (such as isometric force, strain gauges, temperature, pressure, acceleration, displacement and goniometers).

It is available in single or multi-channel configurations. Communication with the computer is achieved through a serial line, allowing multiple sets of units to be controlled simultaneously.

Settings commonly determined by front panel knobs and switches are instead determined by the supplied software including gain and filtering:

Optional Input clamp

The input clamp option is designed for use with triggered subject stimulation where the stimulus would otherwise overload the 1902 amplifier input stages. Such overloads may not be electrically damaging, but the amplifier may take several seconds to regain normal operation after an overload, thus making it difficult to measure fast subject responses to the stimulus.

Important Note

The 1902 is research equipment and is not sold as a medical device within the meaning of the European Medical Devices Directive.
