The RF-E 02 near-field probe detects electric fields that are coupled out of bus structures, larger components or supply surfaces. The electrode surface on the underside of the probe tip is approx. 2 cm x 5 cm in size. The probe is used at a distance of 1 cm to 2 cm from the module.
The RF-E 02 is a passive near-field probe. It has the same basic design as the RF-E 05 and RF-E 10 probes.
For measurement, the lower surface of the probe head of the RF-E 02 is brought close to the measurement object. The E-field emitted by the module is recorded. A higher resolution is achieved if the probe is only brought close to the measurement object with the tip of the probe head. The near-field probe is small and easy to handle. It has a sheath current attenuation and its upper side is electrically shielded. The near-field probe is connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The E-field probe does not have an internal 50 Ω terminating resistor.
