EMC stands for electromagnetic compatibility. It is an important consideration because knowing about compatibility issues can keep electronic devices working properly and prevent them from interfering with other devices. So how can you be sure your equipment and devices are compatible with their environments? It should not be hard to determine compatibility when you have the right kind of EMC testing equipment. Let’s take a closer look at this issue to help you avoid future problems.
What is Electromagnetic Compatibility?
Compatibility means the device should work as it was designed. In other words, there should be no kind of electromagnetic fields generated which can interfere with other devices. Electromagnetic interference can also include issues associated with noises. In other words, the interference may be lines or problems with video signals or humming or buzzing sounds in audio.
History
EMC has a relatively short history, since electrical devices and systems are products of the late 19th, 20th and 21st Centuries. It began when people began to realize telegraph signals could be interfered with. In fact, in the late 1890s the first known law was passed in Europe concerning these issues. It dealt with the proper procedures for preventing electromagnetic interference. In the early years, there was no EMC testing equipment, so many of the procedures were accomplished with trial and error methods.
It wasn’t until the 1920s when EMC became recognized as a problem as radio was becoming very popular. Back then, car engines did not have resistor spark plugs and engines could have a dramatic effect on AM radio signals. By the time radar was invented during the Second World War, electromagnetic compatibility became a major issue as there were more and more technologies to interfere with each other. Today EMC is absolutely essential with modern technology.
EMC in the 21st Century
There are four main factors to consider today for dealing with electromagnetic compatibility issues:
- Identifying and categorizing the type of threat
- Determining what levels of emissions are acceptable or not
- Creating compliance standards
- Testing for compliance
The first three factors are already determined for most companies today. So this makes EMC testing equipment very important. If your company has the need for this kind of specialized equipment, consider a trusted source for all your needs. In addition, it may be much more economical and easier to rent your equipment, as opposed to buying.
