The RF3 mini set consists of two passive near-field probes with a resolution under 1 millimeter for measuring magnetic fields between 30 MHz and 3 GHz on electronic assemblies during the development stage. The probes have special miniature heads which are designed for detailed measurements of magnetic field and disturbance currents in the layout and component range. Field orientation and field distribution on an electronic assembly can be detected by special guidiance of the near field probe. The near-field probes are small and handy. They have a current attenuating sheath and, therefore, are electrically shielded. The near-field probes can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance. We recommend using the passive probes with a 20 dB or 30 dB pre-amplifier.

The H-field probe RF-B 0.3-3 is designed for extreme small-scale detection of magnetic field lines entering at 90° angles into the probe tip. The coil inside the probe head is positioned at a 90° angle from the shaft. For measurements it can be positioned directly onto the measured object.
With its small probe head, the RF-R 0.3-3 can measure magnetic fields in very high resolution. Thus even smallest components can be detected as interference sources. Furthermore, the small probe head is suitable for measurements at hard to reach spots, e.g. near IC pins.
The "SMB-BNC 1 m" measuring cable is a RG174 RF cable with coaxial construction. The wave impedance is 50 ohm. The measuring cable is highly flexible and therefore specially suitable for measurements with near-field probes.
