The B-52 Stratofortress first flew in April 1952. The U.S. Air Force now plans to keep it flying into the 2050s, which would push some airframes toward a hundred years of service. Its original TF33 engines, on...

Machine Vision and the Food Industry: A Perfect Pairing
Do you ever get hungry thinking about vision inspection? That’s normal. The food and beverage industry is a pioneer in integrating machine vision into their production lines. As vision inspection tools...

Near-Field Probes for EMI and EMC Testing
Parts 1 through 3 were all about stopping interference, from shielded enclosures through to ferrites on cables. Now let’s reverse the question: how do you actually see the interference, to confirm your...

How Ferrite Beads and Cores Suppress EMI and Reduce Noise on Cables
In Part 2 we saw how twisting a wire pair cancels interference at the source. But some noise still rides along a finished cable as common-mode current. Suppressing it is the job of a ferrite: a small magnetic...

EMI/EMC Mitigation Technique for Wiring and RF Signal Routing
😮 With FREE Unbalanced Twisted Pair Calculator In Part 1 we covered the basics of RF shielding, how the electric and magnetic fields around a circuit cause interference, and how enclosures contain them....

An Introduction to RF Shielding : What It Is & How It Works
Radiofrequency (RF) shielding is a conductive barrier that keeps the electric and magnetic fields of a circuit confined to where they belong. Left uncontrolled, these fields degrade signals and create...

Defense and Aerospace Testing Standards: What They Cover
If a part is going into a plane or a defense platform, nobody simply trusts its reliability. A dense set of program-specific requirements are created and a significant amount of testing standards offers peace...

Testing Wind Turbines for Green Energy
Wind turbines are particularly massive machines. As key drivers of growth in green energy production, they are nonetheless difficult to build and test. Unlike most systems, a turbine offers little margin for...

In-Circuit Testing for PCB Assembly
In-circuit testing (ICT) is a production test that checks the components on an assembled board, one node at a time. It makes physical electrical contact with the board and measures values such as resistance...
