Abstract:
A scanning unit of a position measuring unit for scanning a scale, the scanning unit including a display unit having a light source. The scanning unit further including a regulating device for controlling an amplitude of an analog scanning signal of the scanning unit, wherein the regulating device triggers the light source to cause a change of an illumination state of the light source, wherein successive changes of the illumination state of the light source contain information regarding the amplitude of the analog scanning signal.
