Abstract:
1. A measuring apparatus, comprising: a transmit-receive device; an offset determination apparatus determining an amplitude offset and including: wherein the control device is adapted, outside a predefinable measuring range of the time-expanded sampling values of a reflection signal, to provide a switch-off signal which can deactivate the transmitter device at least intermittently in order to generate a predefinable quiescent range within the time-expanded sampling values of the reflection signal; wherein the offset provision device is adapted, by evaluating at least one sampling value of the time-expanded sampling values, which value is determined within the quiescent range, to determine a value of an amplitude offset of the time-expanded sampling values of the reflection signal from a normal value and to supply this value of the amplitude offset at an output of the offset provision device; and wherein the control device of the offset determination apparatus is connected to the transmit-receive device.
