The use of electronic test equipment is key to the success of any business that utilizes electronics systems. The custom design and manufacturing of electronic test equipment is used to create signals and capture responses from electronic DUTs or devices under test. The goal of the electronic test industry is to prove the proper operation of a device or trace any faults within its system. This can be accomplished through many different methods and test-specific options, depending on the needs of the client.
Many different kinds of equipment are used for these solutions, including a printed circuit board (PCB) testing an automatic test equipment (ATE). The cost and complexity of standard and custom test solutions can vary. We use more advanced solutions for the development of circuits and systems during production testing than product testing in the field. EMC Technologies provides a wide range of products, services, and solutions to support the needs of our clients and an ever-growing industry.
Testing Requirements for EMI and EMC
Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) are often used together when referring to the electronic testing industry for electronic products. While the terms are unique, they are also related. As a result, many people confuse the meanings for these two different types of testing. The testing requirements for both EMI and EMC can be very complicated, featuring a broad spectrum of industry-specific and even application-specific options.
- EMI is an electromagnetic energy that can affect the function of an electronic device. Sources of this energy can be natural, such as electrical storms and solar radiation. However, EMI can also be interference from another electronic device or system. Some equipment is much more likely to cause EMI disturbances than others.
- EMC measures the ability of a device to operate as intended in a shared operating environment. Devices do not typically operate in an area that is completely clear and devoid of interference. EMC ensures that the product does not affect the ability of other equipment to operate as intended while evaluating how the device will react when exposed to electromagnetic energy. Susceptibility and emissions testing are just two of the types of measurements used by the electronic test industry.
Essential to Design & Engineering
Both of these aspects are essential to any type of custom design and manufacturing of electronic products, devices, and equipment. The failure to accurately anticipate the EMC of a device can result in dire consequences. This is particularly true in some of the industries that we provide our services for, including avionics, military, and telecommunications. Safety risks, product failure, and even data loss can occur if the products are not tested properly. The electronic test industry works to provide engineers with a clear and accurate picture of how the product will operate in real-world situations surrounded by potential interferences.
Manufacturers and developers use EMC testing for many different products across many unique industries. For example, testing for automotive equipment and consumer electronics or appliances is in high demand. The custom design and manufacturing of printed circuit board is also important, as an integral component of the interface test adapter to improve signal integrity and repeatability during testing. EMC testing for lighting products, medical devices, and telecom equipment is also advancing. The work that we do for our military and avionics clients works to improve safety and integrity across the board.
