This is the second of three articles devoted to the design, test, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 performance 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.

Advance military and avionics technologies must be designed to address a range of complex specifications. The use of multiport connectors can provide significant benefits compared with conventional RF/microwave cable assemblies.

Hipot (“high potential”) electrical safety testers produce high voltage to perform dielectric withstand and insulation resistance tests. This article discusses the safety considerations and capabilities of modern hipot testers that utilize electronic source technology to assess compliance with IEC-61010.

While the selection of components in electrical equipment plays a crucial role, a sound understanding of the characteristics of safety-critical and high-integrity components can provide valuable information about the ways to advance and achieve safety goals.

When handling ESD-sensitive components, we must protect them from ESD damage.

Walkie-talkies interfere with electronic door locks on aircraft cockpits.

A common problem experienced by novice oscilloscope users is the inability to effectively capture signals we're trying to measure.
