This video highlights how RF current probes are used to measure high-frequency disturbance currents in a fast and straightforward way. These probes clamp directly around a cable suspected of carrying unwanted signals, eliminating the need to break the circuit and making them far more convenient than setups involving LISNs. Their wide bandwidth-often extending into the hundreds of megahertz-enables quick, reliable diagnostics and supports reasonably accurate prediction models for far-field radiated emissions.
Because of these strengths, RF current probes are firmly established in CISPR 25 for automotive EMC testing and remain a standard tool in both professional and hobbyist environments. They are highly effective for pre-compliance work as well as day-to-day troubleshooting of electromagnetic interference in a home lab. This makes them one of the most accessible ways to understand and evaluate conducted disturbances in electronic systems.
