Patent ID: 7750838

Claim:
A measuring device, comprising: a transmitter ( 6 ) for transmitting ( 38 , 60 ) an ultra-broadband measurement signal ( 16 ) located in a gigahertz frequency range; a sensor unit ( 8 ) for receiving ( 40 , 62 ) an evaluation signal ( 20 ) induced by the measurement signal ( 16 ); and a control unit ( 10 ) for evaluating ( 42 , 66 ) the evaluation signal ( 20 ) in a measurement result, wherein the control unit ( 10 ) is configured to investigate the frequency range for the presence of a signal ( 28 ) that is independent of the measurement signal ( 16 ) with the aid of the sensor unit ( 8 ) for receiving ( 40 , 62 ) the evaluation signal ( 20 ), before transmitting ( 38 , 60 ) the measurement signal ( 16 ), wherein the control unit ( 10 ) is configured to dampen or prevent the transmission ( 60 ) of the measurement signal ( 16 ) when the signal ( 10 ) is detected.
