To determine a shielding material’s potential absorption loss capability, you must first know the frequency or frequencies of concern and, second, what shield materials you have available.

From the entire pool of test equipment available at our disposal as electronics engineers and technicians, the most useful is undoubtedly the oscilloscope. 

The testing of automotive electronic systems requires a sophisticated highspeed 4-quadrant amplifier. Many EMC...

We leave the basics behind and explore more of the state-of-the-art advanced cool features, functionality and specifications that are available in today’s oscilloscopes.

In this article, we describe a method for analyzing data using the FFT algorithm found in Python’s SciPy module. The reader should know that the SciPy module also includes methods for other FFT algorithms, such as the Inverse FFT and Discrete Sine and Cosine methods.

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.

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.

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.

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.

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.
