Electromagnetic Compatibility Testing

”What happens if lightning strikes?”

Electromagnetic compatibility testing, or EMC-RF / EMC testing for short, makes sure that your electrical products and devices don’t emit too much electromagnetic interference. It also ensures that your devices are resistant enough to outside electromagnetic phenomena.

Every major market in the world limits radiated electric emissions, and the limitations apply to all products too. The screen you’re using to read this has undergone extensive EMC testing phases before making it all the way to you. All this works the other way around as well. If there are electromagnetic disturbances, will your device have sufficient grounding, or are there going to be errors or worse? Will your device be alright, even if we place it next to other electric devices? Are your emissions compliant with regional standards? No matter how perfectly you protect your electric product, it will emit electromagnetic interference. 

How hard can it be?

Turns out, very hard. Reliable information on this subject can be hard to come by, but a large study by Intertek Labs estimates EMC testing first time pass rate for regional markets is only 50%. Setbacks from failing tests can be devastating for your new products. With our equipment and expertise, you’ll be well fitted to tackle the challenges of EMC testing – and pass on the first time!

Radiated Emissions Testing

Out of all the EMC testing types, this is the most common one. You measure the strength of unwanted or unintended electromagnetic emissions to ensure they are within permitted tolerances.

You’ll want testing equipment that can rotate the tested object freely. This is because your unintended electromagnetic emissions do not radiate outwards in a uniform sphere. They spike outward only in certain angles. To find out all these emissions, the equipment has to have great maneuverability for the product and the surrounding antenna.

Related testing equipment you’ll want

  • Spectrum analyzer – for measuring the emissions
  • Measurement antennae specifically for your frequencies (ask our staff for more details)

Conducted Emissions Testing

Did you know your devices interfere with the power supply when you plug them in? When you vacuum your floor, the disturbance can be measured in nearby locations in the power grid. Conducted emissions testing makes sure your vacuum cleaner doesn’t affect your neighbors television.


EMC Immunity Testing

Most EMC tests measure what’s coming out of your device, but this time it’s backwards. Simply put, you introduce electromagnetic phenomena to your device and see what happens. These phenomena are split into two categories: continuous and transient. Continuous phenomena are continuous waves and the tests can last for hours. Transient phenomena are short bursts that could last as little as a few microseconds.

EMC immunity testing equipment you’ll want

  • ESD Simulator – They generate electric discharges from the tip of the pistol-like device to “zap” your device. See picture below. Typical failures of this test include resetting of the device, digital logic errors, memory corruption or physical damage.
  • EFT or burst generator – For simulating the effect of toggling a nearby electric switch when your device is in use.
