Page 15: Operation
R&S HZ-14 Operation 2 Operation 2.1 Magnetic Field Probes Any changing current in a conductor will cause a small amount of power to be radiated, it being in effect a transmitting antenna. The amount of power radiated is a function of the magnitude of the current and the dimensions of the conductor compared to the frequency of the current. - Page 16 R&S HZ-14 Operation Care should be taken when applying the antenna factors (AF) to magnetic field measurements, for example use of the supplied antenna factors will be invalid in the following cases: The magnetic field is not uniform over the whole area of the end face of the probe.
