The RFS-R 0.3-3 is a passive near-field scanner probe. The H-field probe is suitable for measurements close to the components in high magnetic electric field strenght range. The coil openings of the RF-R 0.3-3 probe are marked with white dots. Because of its small design measurements can be easily made at hard to reach spots, e.g. between components. The magnetic field scanner probe has a sheath current attenuation and is electrically shielded. It can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The H-field probe does not have an internal terminating resistance of 50 Ω.
