Product Insights: Charged Device Model ESD Testing

This blog explains CDM ESD testing using the field-induced (FI) method, which is important for semiconductor manufacturers. It covers building a CDM-FI tester, waveform details and verification, and qualification nuances. 

Product Insights:Amplifier Operational Classes and Other Important RF Amplifier Specifications

To avoid costly errors in selection, invest the time upfront to gain a basic yet thorough grasp of key amplifier specifications and operating principles before identifying the optimal model for your application needs.

What Every Electronics Engineer Needs to Know About: Working with EMC Test Labs

Choosing an EMC test lab to work with is one of the most important decisions any electronics design engineer or product developer has to make.

Low-Frequency Magnetic Field Shielding

Occasionally, we are asked to help develop shielding effective for near-field low-frequency (LF) magnetic fields, perhaps in a situation where some regulatory agency has imposed limits on LF magnetic field emissions of our product, and we are forced to comply.

Capacitor Technologies Used in Filtering

Although understanding each capacitor type and behavior is daunting and difficult to memorize, it is prudent that every aspiring engineer and technician involved in design for EMC at least have a rudimentary understanding of what capacitor technologies are available.

What Every Electronics Engineer Needs to Know About Oscilloscopes

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

Let’s Talk Oscilloscopes and Their Capabilities Beyond Basic Measurements

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.

No Spectrum Analyzer? No Problem – Use Python’s SciPy Module Instead

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.

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.

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.
