Low Frequency Magnetic Field Probe Kit for EMI & EMC Troubleshooting (9kHz–50MHz

This Low Frequency Magnetic Field Probe Kit is purpose-built for accurate near-field magnetic (H-field) measurements across the 9kHz to 50MHz frequency range, making it an essential tool for EMI/EMC diagnostics, electronic design validation, and interference source identification.

The probe set enables engineers to locate, visualise, and analyse electromagnetic noise directly at the PCB, cable, or component level. Each probe features an electrically isolated probe head and specialised geometry to suit different near-field measurement scenarios, ensuring reliable results while minimising electric field (E-field) coupling.

All probes are passive near-field probes, designed to connect directly to oscilloscopes, spectrum analysers, or RF analysers via a 50-ohm interface for real-time signal observation. When used with an optional RF pre-amplifier, weak interference signals can be amplified for improved sensitivity during advanced EMI investigations.

This solution is widely used in EMC pre-compliance testing, switch-mode power supply analysis, embedded system debugging, RF noise troubleshooting, and industrial electronics diagnostics, helping reduce costly failures during formal compliance testing.
