The 5G era of mobile computing and communications is rapidly moving forward. 5G stands for the fifth generation of wireless infrastructure—a massive upscale of network technology. It will provide data transfer rates faster than the blink of an eye, reducing latency for even the most data-hungry applications, high bandwidth, and greater opportunities for connectivity and … [Read more...]
The Vital Role of Simulation for Virtual EMI and EMC Test Environments
Before deploying microwave and millimeter-wave devices and systems within 5G, the Internet of Things (IoT), and high-speed wireless communication, it is essential to predict their performance. This need has increased the demand for virtual test platforms through simulation software. High carrier and system bus frequencies are necessary for high-data-rate communication … [Read more...]
Ensuring Performance of Connected Home Electronic Products
Towards a Connected Home The title of Bob Dylan’s 1964 hit “The Times They Are A-Changin’” certainly holds true for home appliance products. The world of consumer electronics needs to evolve and keep pace with the growing desire of their customers and play a part in enabling the dream of a truly connected world. The Internet of Things (IoT) trend has finally reached our homes. … [Read more...]
Circuit Level Design and Test for the MIL-STD-461 200 V/m RS103 and the DO-160 Radiated Susceptibility Test at 200 V/m
Introduction For Army, Navy, and Air Force military equipment and DO-160 commercial aircraft avionics, radiated susceptibility test levels as high as 200 V/m may be specified. As always, it is better to design immunity to the test levels into equipment than to wait until equipment is completed and then perform tests. This article assumes the worst-case qualification test … [Read more...]
MIL-STD-461G Passive Device Calibration Review
The Requirement: When MIL-STD-461 revision “G” was issued, I believed that the answer to many of my measurement equipment calibration issues had been solved. Right there in the “Calibration of measuring equipment” paragraph the requirements clearly stated: After the initial calibration passive devices such as measurement system antennas, current probes, and LISNs, require no … [Read more...]
Demystifying EMC in an Electric Vehicle’s Drive Unit
1. Introduction The past decade has witnessed both a leap forward in technology and market expansion of the global electric vehicle (EV) industry [1]. With Tesla leading the market, followed by traditional vehicle original equipment manufacturers (OEMs) such as Volkswagen, PSA, and Toyota, to name just a few, the electrification of the automotive industry has been advancing at … [Read more...]
Review of Induced Signal Susceptibility Testing—DO-160 Section 19
The Issue Induced signal susceptibility has been a factor in electronic equipment performance since the dawning of voltage and current. Often referred to as crosstalk, the undesired coupling of one circuit’s signals to another may result in interference that degrades the integrity of either signal. This article examines the testing process prescribed by RTCA DO-160 Section … [Read more...]
Review of Bonding and Grounding Requirements
The Question What is the required bonding and grounding requirements to achieve compliance with the various electromagnetic compatibility (EMC) standards associated with electronic equipment? I received this question a few days ago and quickly realized that a quick and easy answer was not feasible since I virtually had no knowledge of what kind of equipment types were … [Read more...]
Five Steps for Successful Automotive EMC Design
What makes automotive EMC special? Electronic systems in automotive involve in safety-critical functions which include engine management, braking control, and airbag deployment, to name a few. Also, the automotive industry has seen a new generation of onboard electronics for driver assistance devices and entertainment. Having the mobility of automobile, it can be exposed to … [Read more...]
EMC/EMI Challenges for the Connected Car
ABSTRACT Our automobiles are becoming more connected and reliant on wireless connectivity, and at the same time, the number of high-compute internal systems is rapidly increasing. Like any high-speed, complex digital electronic system, automotive electronics can be both a cause of, and highly sensitive to, electromagnetic interference (EMI), and the consequences of failure can … [Read more...]
