The LF-R 400 H-field probe has a high sensitivity due to its large diameter (25 mm) and is suitable for measurements at a distance of up to 10 cm around assemblies and devices.
The LF-R 400 is a passive near-field probe. With its large diameter (25 mm), it detects considerably more magnetic field than the LF-R 50 (10 mm) and LF-R 3 (3 mm) near-field probes and is therefore more sensitive. However, the LF-R 400 H-field probe has a lower resolution than the LF-R 50 and LF-R 3 H-field probes. 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.
