Doing Things That Usually Do Not Work
“If you’re not making mistakes, then you’re not doing anything.” — John Wooden Over the years, I have seen several things that make me scratch my head. Many of them are things I have done (there, I admitted it). I would like to look at these situations to (maybe) help not to make the same mistakes. So, to be clear: Do not do these things. Concerning Shielding One would … [Read more...]
What is EMC?
Introduction This article will serve as an introduction to the topic. It is aimed at the people who have been told by their management, “You are now my EMC person. Go figure out what it is and how we must deal with it!” It will not be an all-encompassing treatment of the subject, but it will provide the reader with a start and some ideas of where to go for more … [Read more...]
IEC-61000-4-3:2020 4th Edition Containing Multiple Signal Test Option Has Been Published
The new IEC 61000-4-3:2020 4th edition includes the following updates: a description of how to test using multiple test signals; the addition of information regarding EUT and cable layout; the removal of the upper-frequency limitation to take into account new services; and the further specification of how to characterize the uniform field area, as well as added clarification … [Read more...]
New AR Amplifier Spans 10 kHz to 400 MHz Range With 1000 Watts of Power
AR's new amplifier, Model 1000A400, provides CW power up to 1000 watts, covering 10 kHz-400 MHz. In conjunction with AR's accessories and antennas, the 1000A400 is optimal for reaching today's higher radiated and conducted susceptibility test levels, such as the increased conducted immunity test levels of composite aircraft in the frequency range of 10 kHz-400 MHz, along with … [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...]
Würth Elektronik Introduces its WE-CST EE4.4 Current Sense Transformers
Würth Elektronik expands the product family of WE-CST current sense transformers with the new WE-CST EE4.4 series. An innovative manufacturing process not only makes these current sense transformers extremely small (4.7 x 4.65, 3.55 mm), but also provides better insulation. Their insulation voltage of 750 VAC, is 50 percent higher than that of market competitors. The WE-CST … [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...]
