This video walks through a bench-top, mostly standard-compliant conducted-emissions test setup according to the automotive standard CISPR 25 using the voltage method. It covers the complete setup and shows how measurements are performed on both the supply line and ground return, how differential- and common-mode noise can be separated for troubleshooting. youtube.com/watch?v=5nFXRS…

Conducted Emissions on the Bench: This article pulls back the curtain on CISPR 25 conducted-emissions testing, demonstrating how a fully functional voltage-method setup can be built and operated on a standard lab bench. baltic-lab.com/2025/12/conduc…

Is this popular switching converter really EMC garbage? Viewers questioned my setup and the LED load-and yes, both mattered. But even in a proper CISPR 25 setup, the converter still flunks Class 3 limits at just 1 A. youtube.com/shorts/rpPoGAD…

This 2.4-2.5 GHz solid-state power amp pushes 30 W with excellent harmonic suppression. Built on LDMOS tech with a 5th-order filter and VSWR < 2:1. RF engineering at its finest! ⚡📡 youtube.com/shorts/uMW1I6W…

Mains power is dirtier than your ex's browser history. Hook it to an oscilloscope and you'll see just how noisy reality gets. Filtering isn't optional; it's survival. ⚡ youtube.com/shorts/FvgRmeI…

@WurthElectronic I baked some of those in an improvised flowers of sulphur test and compared them against others. They do what they're advertised to do, I couldn't get a single one of the WRIS-RSKS to fail. 👌🏻

In sulfurous air that corrodes standard components, #WurthElektronik's WRIS-RSKS series stands strong. Engineered with ceramic substrates & precision-printed resistance layers, they deliver long-term reliability, even when the air turns hostile. [hubs.li/Q03QPhLQ0] #Blog

What actually happens when the ground plane is missing beneath a signal trace? This video provides a hands-on demonstration of how a break in the ground plane affects electromagnetic compatibility (EMC). youtu.be/YzZHYD0Goog #Arduino , #Arduinoprojects , #Circuitbasics , #Circuits , #Diyprojects, #Electrical , #Electricalengineering , #electronic , #electronics , #ElectronicsTutorials , #engineer , #Engineering , #hamradio , #Maker , #Physics , #Science, #STEM , #tech , #Diyelectronics

High-frequency tech can feel like black magic. Take this ceramic cylinder in an X-band radar. It's a dielectric resonator: a "roundabout" for electric fields, shaping waves via interference to precisely select frequencies. Wild what it can do, right? youtube.com/watch?v=_dHjOH…

Worth knowing: Inductor orientation does matter in practice. Winding direction affects electric field noise! For fast switching, connect the start (dotted end) of the inductor to the switching node to minimize EMI. #electronics #electrical #hamradio #maker

@THYZOID1 Delicious! Don't eat it all at once!

The holy grail of chemistry :3

EMC issues can sneak in unexpectedly - your cables might radiate more noise than your circuit. Learn the key difference between common and differential mode noise and which causes more radiated trouble.

@THYZOID1 It needs an eggplant emoji... Next to the GHS hazard pictogram...

Put the tadalafil into a nice container :3

RF current probes measure high-frequency currents without breaking circuits—-just clamp around a cable. Fast, reliable, and ideal for EMC testing, they're key tools EMI troubleshooting. #Electronics #hamradio #emc #emi

This video tests a popular LM2596 buck converter for EMC compliance (CISPR 25). Common in DIY projects, it often fails emission limits. Real data shows what works-and what doesn't-using LISNs and a near-standard test setup. youtube.com/watch?v=o8WcP9… #electronics #hamr

In this video, a widely used step-down converter based on a Chinese LM2596 clone is examined with regard to its electromagnetic compatibility (EMC). The goal is to clearly illustrate the EMC challenges and evaluate various suppression techniques. youtu.be/o8WcP97md_w #electronics #vanlife #campervan #camperlife #hamradio #CISPR #automotive

A typical example: A 5V device is supposed to be powered from the 12V vehicle electrical system. Online, you'll quickly find a matching step-down converter - 12V in, 5V out. Sounds simple, and usually it works. But this crude CISPR 25 test setup shows that the step-down converter produces conducted emissions far beyond the allowed threshold. #electronics #hamradio #radiofrequency #vanlife #electrical #automobile
