The need for a sinusoidal voltage calibrator and its advantages over a DC calibrator are explained. The construction and operation of a suitable calibrator with variable amplitude and frequency is described. A calibration procedure using the prototype with an electroencephalographic feedback system which includes a Grass Model 7 Polygraph with an electrode selector panel is given. Sufficient detail is included to facilitate adaptation of this calibrator to other systems.
