Note: This is an excerpt from the book, EMI Troubleshooting Cookbook for Product Designers, by Patrick André and Kenneth Wyatt. See Reference 1. Introduction Radiated emissions are by far your highest risk when performing compliance testing at the test facility. With all the high-speed digital circuitry inside electronic products today, it becomes all too easy for harmonics … [Read more...]
5 Ways Signal Noise Can Impact Electrical Equipment
Accurate data acquisition is often critical in various engineering and technical projects. However, a pervasive yet often-overlooked issue that arises in the system is signal noise. This unwanted electrical interference, originating from multiple sources, can corrupt measurements, hinder communication, and compromise equipment integrity. Recognizing the Symptoms: … [Read more...]

Fundamental Oscilloscope Probes
As electronics have become more advanced, so has the equipment used to measure their signal behavior and system performance. In the realm of EMC compliance, oscilloscopes are one of the important tools used to measure signals, hunt down noise sources, and identify time-domain measurements that may contribute to radiated or conducted emissions. Without a properly selected probe, … [Read more...]
The Voltage Rises
Santa Rosa, California, July 24th, 2023 – In the past, automobiles had minimal electrical systems and relied mainly on mechanical systems. Today, there are many electrical functions such as seat heating and cooling, comfort systems, and assistance systems that draw a lot of electricity from the battery. In a 12V vehicle electrical system, higher and higher currents must flow. … [Read more...]
Radiated Emissions Testing
INTRODUCTION Radiated emissions testing is only one part of emissions testing. CISPR 32, the document that lays out limits and methods of measurement for emissions (radiated and conducted) for Information Technology Equipment (ITE), broadcast receivers and multimedia equipment is 120 pages in length. ANSI C63.4 deals with only the testing part (limits are contained in a … [Read more...]

Protecting RF, Receiver, Analog and Control Line Input Circuits Against The RTCA DO-160 Pin Injection Lightning Test
ABSTRACT Circuits are described that effectively protect RF, receiver, analog, and control line input circuits from three types of transient injection, described in DO-160, directly into the input pin of the connector. The goal was to achieve a circuit which would not adversely affect the performance of the RF circuit over an input frequency range of 20MHz to above 1GHz … [Read more...]
