Don MacArthur explains spectrum analyzers, tools for frequency domain analysis of signals. He covers their functionality, key parameters (center/span, reference level, RBW, VBW), types, and usage. MacArthur emphasizes their importance in electronic measurements and provides tips for preventing damage to the devices. 

Ken Wyatt provides an overview of radiated emissions pre-compliance testing. He covers equipment setup, field strength calculations, and strategies for managing ambient interference. The guide aims to enhance EMC troubleshooting skills and reduce formal testing expenses.

Patrick André discusses the misconception of "ground" in electrical engineering. He explains the difference between true ground and power/signal returns, emphasizing the importance of proper return line treatment in circuit design. André highlights how this understanding impacts EMC performance and system design across various applications.

This blog by Don MacArthur discusses how to measure creepage and clearance distances on printed circuit boards (PCBs) to ensure safety. It covers definitions, design guidelines, measurement techniques, and tips for compliance engineering in electrical product safety.

Morse code: not just dots and dashes from the past! From secret military comms to life-saving SOS calls, this 'outdated' system is buzzing with modern uses. Discover how it's thriving in tech, emergencies, and a passionate amateur radio community.

When developing electrical or electronic products that use shielded cables, a common question arises: Where should cable shields be grounded? At one end? Both ends? Or not at all? Don MacArthur aims to offer a starting point for formulating your own response based on your specific situation.

Explore the correct use of UL iQ for Electrical Insulation Systems and how proper utilization can save time and money during product development.

Ken Wyatt's blog explores DIY radiated emissions testing. He breaks down the gear you'll need—think spectrum analyzers and special antennas—and shows how to set up your own test space without breaking the bank. It's all about catching EMC issues before the big, pricey lab tests.

The blog discusses various types of bandwidths used in EMC measurements, including receiver bandwidth, resolution bandwidth (RBW), and video bandwidth (VBW). It explains their differences, importance in testing, and challenges in measuring low-amplitude signals at high frequencies.
