Frequently asked questions about EMC test & measurement technology
The abbreviation stands for electromagnetic compatibility and refers to the ability of electrical devices or systems to function in an electromagnetic environment without interfering with other technical devices or being interfered with by other devices. Potential interference can be caused by electromagnetic effects or by conducted effects. During normal operation, every electrically powered device generates electrical and electromagnetic signals that can affect other devices. This is why legal limits have been set for electromagnetic susceptibility (EMS) and electromagnetic interference (EMI). Compliance with these values must be verified with the help of an EMC testing laboratory.
This verification is a prerequisite for affixing the CE mark to products, for example, so that they can be introduced to the European market. Similar regulations also exist for markets outside the European Union. However, other markets may have different rules and limits that must be complied with. Additional regulations apply to areas of application such as aviation, medical technology, and automotive.
External EMC certification may only be implemented by accredited laboratories. This requires a wide variety of EMC test and measurement equipment. This ensures that certification is a time-consuming and cost-intensive task. This is the reason why many companies react accordingly and try to identify EMC problems already during development so that they can be corrected accordingly. In this way, it is possible to avoid potential problems only coming to light during EMC certification, as this would interrupt the certification process in order to implement product changes. This not only has a negative impact on costs, but also on time-to-market.
The appropriate EMC test and measurement equipment can also be used for internal self-certification. Many EMC problems can be quickly identified, analyzed and eliminated. However, the purchase of EMC test and measurement equipment is also expensive and requires knowledge of these applications and standards.
We manufacture standard-compliant EMC test and measurement equipment that you need to ensure smooth workflows in your laboratory.
For EMC test and measurement equipment, the first thing to look for is the right choice of standard. This advice can be easily followed if there is an EMC product standard for the device or system to be tested. If this is not the case, the test is performed according to the basic EMC standards. In addition, the operating state for the measurement of the emitted interference should be observed. The same applies to the operating state for the immunity test. Also to be considered are malfunctions during the immunity test, for example by monitoring using an EMC-proof camera. Last but not least, it is also necessary to decouple the auxiliary devices, since only the function of the EUT is to be assessed.
As a rule, an electrical or electronic product falls under the EMC directive (2014/30/EU). This European directive defines products and the corresponding procedure. As soon as your product falls within the scope of this directive, you as the manufacturer are obliged to prove the conformity of your products with technical documentation. With a corresponding test report after a successful test, this proof can be easily provided in practice.
Depending on the required standards, a selection of different devices is available. You can find the corresponding test systems under our standards or contact our customer service directly.
