Tackle radiated emissions before heading to the test lab. This practical guide covers the essential workbench toolkit — near field probes, RF current probes, and spectrum analyzers — including DIY options and affordable commercial choices for identifying noise sources and reducing cable emissions.

Spectrum analyzers are essential for EMC testing—but only when used correctly. From setup and calibration to antenna selection and data interpretation, this guide covers best practices to ensure accurate measurements and smooth compliance with regulatory standards.

Looking beyond the equipment, EMC compliance hinges on precise antenna performance. This blog examines how construction materials, proper setup techniques, and regular maintenance affect measurement accuracy. Learn why high-conductivity metals, careful calibration, and consistent care are essential for reliable testing that ensures your products meet regulatory standards.

This article presents the derivation of the radiated far fields from a Hertzian dipole antenna above the ground plane using image theory.

This article presents the derivation of the far-field criterion for two fundamental wire-type antennas: electric (or Hertzian) dipole and magnetic dipole.

Antennas come in many different types, and it can sometimes be overwhelming to decide which one fits the need the best. In the case of immunity antennas, the correct selection may be the difference of reaching field and not. The antenna is the most important part of the system. Given that the amplifiers can be the costliest part of the system, one needs to take the time to research and find the correct antenna to make the best use of the available power.

Antennas come in all shapes and sizes and can be used for both radiating and receiving. Selecting a good receiving antenna for emissions testing is not difficult if you take some necessary items into account.

Antennas used for EMC testing possess several characteristics which make them ideal for use in a fast-paced, production-like EMC test environment. This article will briefly describe what these characteristics are, starting with the most important parameter – antenna factor.

With the help of a brand-new low-frequency miniature antenna, mobile robots will enjoy powerful networking even in complex environments.

Part II of this two-article series focuses on log-periodic and biconical antenna impedance, VSWR, and radiated emissions measurements.
