Abstract

A distance measuring device has at least one oscillator (26) which produces a basic signal at a fundamental frequency (f0) and a first circuit device (30) which produces a first signal at a first frequency (f1) which is higher than the fundamental frequency (f0). The first circuit device (30) has at least one PLL circuit (32) and one VCO circuit (34).
