Software control
The A-M Systems multi-platform software controls all Model 4100 functions, and takes full advantage of today’s operating systems to make implementing your research protocols easy and straightforward.
Common "pinch and spread" touchscreen gestures can be used to change waveform timing and amplitudes; Dragging waveform icons can quickly rearrange the stimulus pattern delivered during a train.
Error messages as well as status messages are clearly displayed.
Multiple instrument programs can be stored on your computer to enable users with different protocols to preserve their settings and quickly import previously used values.
