The LF-U 2.5 H-field probe is a near-field probe. It is used to selectively detect the HF current in conductor runs, SMD components and IC pins. The probe head has a magnetically active gap of approx. 0.5 mm in width.
The LF-U 2.5 is a passive near-field probe. It has the same operating principle as the LF-U 5 probe. The LF-U 2.5 is suitable for SMD components (pins) and the LF-U 5 for larger components such as cables, connectors, etc. For measurement, the probe head with the magnetically active gap is placed directly on the object to be measured. The near-field probe is small and easy to handle. 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.
