The RF-E 02 is a passive near field probe. In principle it has the same structure as the RF-E 05 and RF-E 10 probes. For measurements the under surface of the probe head is positioned close to the measured object. This allows the E-field which is emitted by an assembly to be detected. To achieve a higher resolution only the top of the probe head should be held toward the measured object. The near field probe is small and handy. It 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.
