In the installation of a scanner of a position measuring apparatus, it is required that parameters such as amplitude and phase position of analog signals generated by a scanner be tested so that the scanner can be correctly installed. For this purpose, a control device with a display
In the installation of a position measuring device it is necessary that parameters such as amplitude and phase position of the analog scanning signals as well as the position of the reference mark signal are tested. In order to accomplish such testing, a control device is provided that h
