The RF-R 400-1 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 RF-R 400-1 is a passive near-field probe. It has the same basic design as the RF-R 50-1 and RF-R 3-2 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.
