Using the approx. 4x4 mm electrode, which is located in the bottom of the RFS-E 03 probe head, E-fields from clocked lines, IC pins, and smaller components can be detected.
The RFS-E 03 is a passive near-field probe. For measurements the E-field probe is positioned above the components or areas of the PC board. The near-field 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. It does not have an internal terminating resistance.
