摘要:
The invention relates to a measuring device comprising a signal unit (20) for emitting a measuring signal (22.1, 22.2) in a measuring frequency range (60, 62, 68, 70) adapted for measurement and an evaluation unit (36) for the spectral evaluation of an evaluation signal (34.1, 34.2) induced by the measuring signal (22.1, 22.2) to a measuring result. According to the invention, the measuring device comprises a signal processing unit (30) adapted to displace a generation signal (26) for generating a measuring signal (22.1, 22.2) in a generation frequency range (48) from the generation frequency range (48) to the measuring frequency range (60, 62, 68, 70).

The invention relates to a locating device, in particular a hand-guided locating device, with a locating unit (36) for detecting the presence of an object (16, 18) arranged in an examination object (14) by means of an examination signal (38), which has a polarization unit (50) provided for a procedure with the examination signal (38), and with a housing (20) for taking up the locating unit (36), which has a longitudinal axis (24). It is proposed that in at least one operating mode the polarization unit (50) specifies at least one first polarization plane (52, 54) aligned obliquely to the longitudinal axis (24).

摘要:
The invention relates to a measuring device comprising a transmitter (6) for transmitting (38, 60) a measuring signal (16) that lies within a frequency range, a sensor (8) for receiving (40, 62) an evaluation signal (20) that has been induced by the measuring signal (16) and a control unit (10) for evaluating (42, 66) the evaluation signal (20) to produce a measured result. According to the invention, the function of the control unit (10) is to check the frequency range before the transmission (38, 60) of the measuring signal (16) for the presence of a signal (28) that is independent of the measuring signal (16).
