Questions to Ask When Purchasing Fiberoptic Links and Camera Systems Used for EMC Testing

EMI-shielded fiber optic links and cameras are revolutionizing EMC testing by ensuring accurate data transfer, real-time monitoring, and reliable analysis in the presence of electromagnetic interference.

Cavity Resonances of Shielding Boxes and Cans

Many years ago, the author experimented on a metal enclosure of one of his company’s main products. The experiment involved placing an electric field probe inside the empty metal enclosure (no electronics inside) and applying 10 V/m using the IEC 61000-4-3 radiated RF immunity test system.

Questions to Ask Before Purchasing a TEM Cell or GTEM Cell

When it comes to conducting electromagnetic compatibility (EMC) testing, TEM (Transverse ElectroMagnetic) cells and GTEM (GigaHertz Transverse ElectroMagnetic) cells are widely used for their ability to generate controlled and repeatable test environments.

System Components Used to Reduce Electromagnetic Interference

A few basic system components are frequently used to mitigate or suppress electromagnetic interference (EMI) in devices. As engineers and technicians involved in compliance engineering, it is important to know what these components are, what they do, how they’re most effective, and when they’re ineffective.

The Importance of High Frequency Measurements

Before diving too deep into the nitty gritty of high frequency probing techniques, it’s imperative to understand a few basics, as described in the remaining portion of this article. The basics include probe calibration and null measurements and a description of the various types of voltage probes available, including their strengths and weaknesses.

Questions to Ask When Looking for the Correct RF/Microwave Power Amplifier for EMC

High-power RF/microwave amplifiers are commonly used in EMC (Electromagnetic Compatibility) testing to meet radiated and conducted immunity requirements. These products can be a high overall cost, and selecting the correct models that meet your needs is imperative.

Questions to Ask When Looking for an EMC Immunity Antenna

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.

Why it is Important to Control and Measure CDN Impedance per IEC 61000-4-6

Introduction IEC 61000-4-6 is titled “Electromagnetic compatibility (EMC) - Part 4-6: Testing and measurement techniques...

IEEE Recommended Practice for Antenna Measurements

Even if you are not involved in the practice of the measurement of antennas but have a passing interest and would like to learn more, this is the standard to read. Doing so will quickly get you up to speed, saving you many hours of unnecessary research and much confusion.
