Features

A major advantage of programmable amplifiers is the degree of interaction between the signal conditioner and the application software recording the data. The 1902 is directly controlled through the CED data acquisition and analysis programs Spike2 and Signal, or through a stand-alone control application.

  • Trigger input converter from high-level pulses or switch closures to 5V TTL
  • Overload indicators with software readback
  • EMG filter with full wave rectifier and programmable post-filter gain
  • 16-bit ADC for digitisation of transducer and other low-bandwidth signals and transmission of results down the serial line
Software controllable features

  • Programmable gain with readback
  • Digital filters generated according to user-entered filter cut off values
  • Optional input clamping
  • Selectable mains notch filter
  • AC/DC coupling
  • Dynamically controlled 12-bit offset

The isolated electrode input

The 1902 is designed to a specification worked out in conjunction with major UK physiological laboratories for an isolated amplifier to comply with EN 60601-1. It provides a low noise differential electrode input developed specifically for EEG, EMG, ECG and evoked potential applications.

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

The transducer input port (non-isolated)

The transducer input port is suitable for use with a wide range of bridge and other transducers. It will accept single-ended and differential inputs and provides 5 volt and 12 volt outputs to supply the excitation voltages required by many transducers. Applications include: isometric force, strain gauges, temperature, pressure, acceleration, displacement and goniometers.

The 1902 is available in a transducer-only form with no isolated electrode input.
