Both aspects of EMC-EMI are important design and engineering considerations in any system. Failing to consider them in the early stages of product development can result in the time consuming and costly need to redesign the product at a later stage to meet EMC/EMI specification tests and prevent product failure or a safety risk.
As a result, a wide range of testing equipment for EMC and EMI has been developed to give engineers a clearer picture of how a device will operate in real-world conditions.
EMC-EMI testing is broken down into two categories.
EMC-EMI Testing Routines
EMC-EMI Testing Stages
In order that a product may pass its EMC compliance, the EMC testing should be undertaken at various stages of the life of the product. Broadly there may be considered to be four stages involved in EMC test:
It is useful to be able to categories the different stages of EMC test as the requirements for each are slightly different and different approaches may be taken.
EMC-EMI test types
The testing that is required for EMI EMC compliance falls into a number of categories. Some elements of EMC testing are essential whereas others may be advisable to perform at the various stages during the development cycle of the product.
The device’s intended application will determine the exact type of testing required. Key questions to ask are:

To assess the EMC of a device or system, technicians perform four basic types of tests: radiated immunity, radiated emissions, conducted immunity and conducted emissions.
EMI/EMC testing is a critical step in bringing a new product to market. Emissions testing – measures the amount of electromagnetic noise generated by a device during normal operation. The purpose of these tests is to ensure that any emission from the device is below the relevant limits defined for that type of device.
The EMC standards define the frequency range and limit of unnecessary radiation to prevent telecommunication and broadcasting devices (such as those that use an assigned frequency range for radio communication) and electrical/electronics devices from being interrupted, causing interference, or other similar problems.
EMI/EMC testing is a critical step in bringing a new product to market. Emissions testing – measures the amount of electromagnetic noise generated by a device during normal operation. The purpose of these tests is to ensure that any emission from the device is below the relevant limits defined for that type of device.
EMC certifications are a mandatory requirement in most markets, including Europe, the US, China, Korea, Australia, Gulf and New Zealand. EMC testing is necessary to help you meet regulatory requirements, improve product performance and reduce the risk of costly non-compliance.
