Why automotive harness length changes test results
Change the length of an automotive harness by just a few centimetres and you can shift a radiated emission peak by tens of megahertz. Harness geometry is one of…

Why pre-compliance scans can differ from final testing
It’s not unusual for a product to pass a pre-compliance scan in the lab, only to fail the formal compliance test weeks later. The difference is rarely due to lu…

Radiated immunity challenges in rail environments
Unexpected field strength spikes from a passing train can induce a system reset in a trackside controller—often only once every few weeks, and only when the win…

Defence EMC report checklist
One missing calibration certificate or ambiguous photo can stall a defence EMC submission for weeks. Here’s how to ensure your EMC report stands up to scrutiny,…

EMC lab vs in-house testing: which suits your project
One poorly grounded LISN or an uncalibrated receiver can turn a six-week compliance sprint into a six-month product delay. Choosing between EMC lab vs in-house…

ISO 11452-4 harness excitation testing explained
Most automotive EMC failures can be traced back to the wiring harness—yet few engineers have seen just how much unwanted current can couple onto those cables du…

How to test immunity on a prototype board
Many prototype boards pass functional tests, then fail EMC immunity at the worst possible moment—when the design is locked and the market launch is at risk. Wh…

Industrial EMC case study: noisy motor control board
Unexpected radiated emissions from a new motor control board forced a full production halt—just days before formal compliance testing. Typical scenario Industr…

Common EMC failures and what they usually mean
Seeing a spike at 120 MHz on the spectrum analyser, or a radiated immunity failure at 10 V/m, is rarely random. Most common EMC failures are predictable—if you…

How to decide whether to retest or redesign
One failed EMC test can derail a product launch, but the wrong recovery decision can cost far more than the test itself. Typical scenario Picture a new industr…

EMC testing checklist before compliance testing
One missed test cable or an ambiguous operating mode can waste half a day in the chamber—and cost a project its margin. Here’s a hard-learned EMC testing checkl…

How to choose EMC equipment for industrial drives
Introduction Industrial drives—especially variable speed drives and inverters—are essential in modern automation and manufacturing. However, these devices can i…
