Testing devices for electromagnetic compatibility (EMC) ensures that electronic devices and systems function properly in their environment without interfering with each other through electromagnetic interference. This means that devices are both protected against interference and do not themselves cause any unwanted emissions that could affect other devices.

In order to design EMC in the field of electrical engineering and electronics in a safe and uniform manner, a committee - the International Electrotechnical Commission (IEC) - has defined IEC standards and ISO standards, in part with the International Organization for Standardization (ISO). As electronics and electrical engineering are now built into most systems and installations, various EMC standards apply across all industries and must be certified in defined processes. We have developed devices for measuring and testing technology for various industries:

• Industry (general)
• Automotive
• Military and defense
• Medical sector
   

Development and EMC measures

EMC aspects should already be taken into account during the planning phase of a device's layout and design in order to identify potential problems. Regular pre-compliance tests reduce time-consuming and cost-intensive subsequent corrections and avoid delays in the final certification process. Standard-like simulations in a laboratory environment and measurements of emissions and immunity (interference immunity) are carried out.

Finally, measuring and testing equipment is used to test the devices for EMC conformity in compliance with legal standards before they are put into operation to ensure that they do not cause any interference and are protected against interference.

Appropriate measures are required to ensure safety and unrestricted functionality. Good shielding of electronic housings and shielded cables, e.g. with a special ferrite coating, reduce electromagnetic emissions, reflect or absorb electromagnetic waves and thus block their interference.

Interfering signals are suppressed and eliminated using suitable components such as filters and attenuators. Optimized PCB layout can also eliminate unwanted emissions.
