Short description

The H-field probe LF-R 50 is designed to measure assemblies, devices, or cables at a distance up to 3 cm. This allows larger components to be detected as possible sources of interference.

The LF-R 50 is a passive near-field probe.

Due to its diameter, sensitivity, and resolution the LF-R 50 functions between the ranges of the LF-R 400 and LF-R 3 near-field probes.

The near-field probe is small and handy. It has a current attenuating sheath and, therefore, 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.
