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...]
Test 5G Bands without Massive Cost of New RF Equipment and Time to Train RF Engineers
ThinkRF Corp., the leader in software-defined spectrum analysis, today announced the launch of its new ThinkRF D4000 RF Downconverter/Tuner. The platform is the industry’s first 40 GHz downconverter/tuner that offers a frequency range of 24-40 GHz with up to 500 MHz of real-time bandwidth (RTBW), to capture mmWave 5G signals. Now, engineers can quickly and reliably analyze new … [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...]

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 Simulation for Automotive Ethernet
Introduction The increasing use of electronics in vehicles introduces new risks of interference and crosstalk between components. OEMs and government regulators impose strict limits on electromagnetic interference (EMI) and electromagnetic compatibility (EMC), and redesigning a component that fails to meet these standards can be both expensive and time-consuming. This article … [Read more...]
Advanced Test Equipment Corporation and PMM Finalize New Agreement
Advanced Test Equipment Corporation (ATEC) announced the finalized agreement between ATEC and PMM—making ATEC the new United States and Mexico sole distributor and authorized service center for calibrations and repair of PMM equipment. ATEC is a worldwide leader in test equipment rentals, sales, and calibrations, providing companies with EMC and other equipment that meets all … [Read more...]
Flexibility Key to Trends in EMI Pre-Compliance Debugging
EMI analysis continues to expand as more companies add electronic control and wireless remote capabilities to their products. The need to drive speed and efficiency throughout the design process means these engineers need to conduct EMI pre-compliance testing on the same bench as the debugging embedded and RF signals. Modern instruments often combine debugging and … [Read more...]
EMC Test Equipment Selection and Sizing
Explosive growth in technologies like portable electronics, Internet of Things (IoT) devices, and autonomous vehicles has led to a world full of electromagnetic interference. Efficient EMC testing is more critical than ever, and is dependent on high-quality test equipment. Historically, not a lot of education has been provided on the careful considerations needed for … [Read more...]
