Signal Integrity Versus EMC
This article addresses two very common questions involving two interrelated and specialized sub-fields within the realm of compliance engineering.
Use of Ferrites in PCB Reference Planes
Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.
Post-layout Signal Integrity/Power Integrity Simulation Software Expectations
Discover the most important post-layout elements when selecting a SI/PI software simulation package.
How to Select Absorbing Materials for Retrofitting
If you think you’re ever going to need to use flexible RF absorber sheets to help your product pass emissions, even at some later date, it might be a good idea to have already identified and obtained the material and have characterized its insertion-loss performance.
The Calculation of Creepage and Clearance Distances Using a Spacings Calculator
The calculation of creepage and clearance distances (spacings) is one of the most important activities a product safety/compliance engineer or technician performs throughout the product development process.
The Synergy of Filtering and Shielding
This article briefly describes the concept of the synergy of filtering and shielding and why knowing it is important.
Power Amplifier Linearity Requirements per IEC 61000-4-3
Introduction
The 2020 edition of IEC 61000-4-3 contains several significant technical changes. According to the forward of the standard, the specific changes are:
testing using multiple test signals has b... Read More...
How Not to Blow Up Your Spectrum Analyzer
Spectrum analyzers are expensive pieces of equipment that should be handled with care, especially when it involves applying signals to the RF input. Some new users may not know what “care” means and how to go about ensuring the spectrum analyzer they’re using is protected from overloading and damage.
The Importance of Considering RF Suppression Techniques Early in Design
This article briefly describes why it's important to consider what RF suppression/filtering techniques will be applied to your product as early in the design process as possible.
Requirements of Antennas for EMC Testing
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.
