ABSTRACT:
A position measuring device has an incremental dimensional standard and also an associated scanning unit that emits at least two analog, phase-shifted periodic output signals and a monitoring device, so that a value of the output signals emitted by the scanning unit codes a state of the monitoring device. The scanning unit includes a sensor for scanning the dimensional standard, which generates at least one analog sample signal, and an evaluating unit, based on the sampled signal, determines a position value, while a synthesis device synthesizes phase-shift, periodic output signals based on the position value.
