The RF-U 2.5-2 near-field probe is used to selectively measure the RF current in conductor runs, component connections, SMD components and IC pins. The probe head has a magnetically active gap approx. 0.5 mm wide. This is placed on the measurement object for measurement.
The RF-U 2.5-2 is a passive near-field probe. It has the same operating principle as the RF-U 5-2 probe. The RF-U 2.5-2 is suitable for SMD components (pins) and the RF-U 5-2 for larger components such as cables, connectors, etc. The near-field probe is small and handy. It has a sheath current attenuation and is electrically shielded. The near-field probe is connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The H-field probe does not have an internal 50 Ω terminating resistor.
