Oscilloscope Probe Considerations

A basic knowledge of the probe types and their performance capabilities is important because their operation can affect the whole system under test and measurement results obtained.

Protection of High Voltage Power Substation Control Electronics from HEMP and IEMI

This article discusses techniques for assessing the effectiveness of existing shielding and penetration protection in power substations against early-time, high-altitude electromagnetic pulse (E1 HEMP) and intentional electromagnetic interference (IEMI).

Lightning and RF Electrical Bonding

Everything you need to know about the lightning and radio frequency bonding requirements in military and aerospace standards (and nothing you don’t!)

SCIF and Radio Frequency Secured Facility Design

Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 design requirements, creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.

Avoiding Supply Chain Disruptions of Safety-Critical Recognized Components

End-product manufacturers can help protect against supply chain disruptions that impact the availability of listed or recognized components by proactively identifying suppliers who can provide substitute components that conform with their listing requirements.

Evaluation of EMC Emissions and Ground Techniques on 1- and 2-layer PCBs with Power Converters

This is the second in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.

The Relationship Between EMI/EMC and ESD

The 2020 EOS/ESD Symposium featured a new EMC Special Session, organized in cooperation between the EMC Society and EOS/ESD Association. This Special Session was planned to emphasize the relationship between EMI/EMC and ESD.

Banana Skins – June 2021 (#333-341)

The rear-screen heater in my BMW 3-Series causes so much interference when switched on that it’s impossible to listen to the car radio.
