EMC Tips and Tricks

Get to Know the EMC testing process

Rigorous testing is involved in any reliable product, and electronics are no exception. While EMC testing may feel like a big mystery starting out, AR is here to give you the easy version and start you on the right path to electromagnetic compatibility.

Let’s get back to basics. EMC testing is a necessity in all things electronically powered so that devices run smoothly and don’t interfere with existing electrical systems. Proper EMC testing reduces the risk of interference or damaged equipment, whether we’re talking about network cellphone usage or aircraft electronics.

Immunity versus Emmissions Testing

While different industries and countries may have particular standards, EMC testing is generally divided into two types: immunity and emissions.

Immunity testing measures how a product functions when other external signals are present, while emissions testing measures the signals emitted by the product itself. These tests are generally administered either with signals sent via cables (conducted testing) or with signals sent or read from antennae (radiated testing).

On top of the relief provided by meeting standard ratings, that your product will pass certification standards, EMC testing with AR products will reduce your costs in comparison with large testing facilities. Ensuring trusted products ahead of large-scale production is always ideal, not to mention less warranty and service issues for your team to handle in the long run.
