Consumer demand for more entertainment, safety, and communication options within automobiles has significantly increased both the density of electronic components and the number of on-board wired and wireless signals. The result: an ever-expanding range of signals contained within the same car-sized fixed space. USING AN OSCILLOSCOPE TO VERIFY EMC TESTS FOR AUTOMOTIVE … [Read more...]
Basic EMC Concepts
Introduction Understanding EMC is all about two important concepts: (1) all currents flow in loops and (2) high frequency signals are propagated as electromagnetic waves in transmission lines. Currents Flow in Loops These two concepts are closely related and coupled to one another. The problem we circuit designers miss is defining the return path back to the source. If you … [Read more...]

Connectivity for Off-Road Vehicles – Part 3
Zonal Architecture for Vehicles Zonal architecture is the name given for the new structure of vehicle electronics. In contrast to a traditional vehicle in which systems are grouped by function, zonal architecture offers a more efficient solution. The functions within a vehicle are grouped by location into several zones. Each zone is responsible for the devices that are … [Read more...]
Connectivity for Off-Road Vehicles – Part 2
The Future of Vehicle Design The next generation of vehicle design will be influenced by four key trends. The first is electrification – the adoption of hybrid and all-electric power as alternatives to traditional fossil fuels. The use of electric power by commercial vehicles has become commonplace in the urban environment, where operators have easy access to charging … [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...]
