ABSTRACT:
The invention is based on a distance-measuring device having a transmission unit (20) for generating a transmission signal (42) having at least one measurement frequency (f1, f2) which is desired for detecting distance information. It is proposed that the transmission unit (20) comprises a means (60) for generating an evaluation signal (62) having an evaluation frequency (fA) which is desired for evaluating the distance information.
