High Frequency Magnetic Field Probe Kit – 30MHz to 3GHz

This high frequency magnetic field probe kit is a professional near-field measurement solution for engineers and technicians involved in EMI, EMC, and signal integrity analysis.

The kit includes four passive magnetic field probes, each with a different probe head geometry to suit a wide range of near-field measurement scenarios. These probes are optimised for detecting high-frequency magnetic fields (H-field) while being effectively shielded from electric field interference, allowing accurate identification of radiated noise sources.

All probes are passive and connect directly to an oscilloscope or spectrum analyser via a 50 Ω RF cable, enabling real-time magnetic field measurement and analysis. When measuring very weak interference signals, the probes can be used in conjunction with a 30 dB RF pre-amplifier to improve system sensitivity.

This probe kit is widely used during pre-compliance testing, fault isolation, PCB debugging, and EMI troubleshooting to help identify and resolve potential EMC issues before formal certification testing.
