Cost-Effectively Ensure Electromagnetic Compatibility in the Age of IoT
Wireless/RF is ubiquitous, so implement a pre-compliance regimen with off-the-shelf equipment. Every electronic product has to go through full electromagnetic compatibility (EMC) testing to get the much-coveted stamp of approval from the various regulatory bodies. This has traditionally been a costly undertaking with multiple trips to a distant testing facility, with … [Read more...]

This is post 2 of AR’s blog series “Specifying RF/Microwave Power Amplifiers for EMC Testing.” The full series can be viewed here. INTRODUCTION How much input power is required to achieve full rated output power is a common concern when choosing an amplifier. Amplifier manufacturers have specified an input of 1 milliwatt. (Note that this is not the case for every … [Read more...]
Risk Mitigation: Advanced ESD Instrumentation for Qualification Testing of Static Shielding Bags
Today, Suspect Counterfeit ESD Control and Non-Compliant Packaging is a growing issue throughout the Global Supply Chain. EEE parts (ESD sensitive devices) damage transcends circuit cards, touch screen displays, handheld devices, and other microprocessor driven products. Suspect counterfeit static control or non-compliant electrostatic discharge (ESD) shielding bags can be … [Read more...]
In Memory of Bob Goldblum
Good morning. My name is Graham Kilshaw and it is my honor to offer this eulogy in honor of my father in law – Bob Goldblum. It was only 35 degrees outside when Bob was born, December 18, 1935 in Philadelphia, and the economy wasn’t that warm either. After all, most of the country was considered far from comfortable at that time. The Wall Street Crash had occurred just 6 … [Read more...]
