What is an EMC Design Review? An EMC Design Review focuses on particular EMC issues. It is not a full blown review as it does not consider issues like weight, power, reliability etc. An EMC design review can cover mechanical issues, system level issues or circuit board issues, depending upon the product. It also throws light on regulatory requirements as well as threats, various constraints like volume and cost constraint, and design strategies. When is the Best Time to Perform the Review? Generally, the best time to conduct an EMC Design Review is in the initial mechanical and electrical des ..read more

Continued From Part 1… GTEM Cell GTEM Cell: GTEM Cells are like mini semi-anechoic chambers. GTEM cells can be used both for emission testing as well as radiated immunity testing. For this pre-compliance option, you would need a GTEM along with a spectrum receiver/analyzer. The equipment under test is placed inside the Gigahertz Transverse Electromagnetic (GTEM) Cell, between a resistive load and antenna. Though the GTEMs vary in size from small (50 cm) to a few meters, but the size of the EUT is restricted to a cubic area only within the GTEM. Due to the small dimensions, it is very easy to ..read more

Having already discussed about Pre – Compliance Testing, in this post we will discuss about 3 out of 5 of the pre-compliance options available for radiated emission testing. Design Review: This is one of the most overlooked pre-compliance method. Design review isn’t really a pre-compliance testing method but it does the same thing. It is designed to reduce the risk of the failure of the product in an EMC Test. There are numerous textbooks that can provided with the needed guidance. This method increases your chances of passing the test in one go because you can identify so many emission and ..read more

Electromagnetic Compatibility concerns with the unintentional generation, propagation, and reception of electromagnetic energy. EMC compliance testing ensures that damage in operational electronic equipment or unwanted effects like electromagnetic interference (EMI) are not present. The aim of EMC Testing is to ensure smooth operation of different equipment in a shared electromagnetic environment.  In the last post, we talked about pre-compliance testing. In this post, we will talk about compliance testing. Pre-Compliance is a cost-effective, low risk, and an informal method to ensu ..read more

To improve your chances of succeeding in an EMC Test, pre-compliance testing is a great approach. It is true that most of the companies don’t do any pre-compliance testing before sending their products to a test lab and some even succeed in clearing the EMC Test in their first go. However, this does not reduce the importance of this step and the fact that, the chances of failing the test can induce additional cost and delays for the company, cannot be ignored. Pre-compliance testing attempts to transform an unknown risk into a known risk. It tries to give a higher level of assurance that the p ..read more

Electromagnetic Compatibility Immunity Testing can be either transient or continuous in nature. Transient phenomena are generally short events that involve bursts of energy. Continuous testing is used on a product to replicate RF proximity that might occur in the real world. Requirements of EMC Immunity Testing are often categorized on the basis of how EMI might couple onto a device: Immunity, telecommunication ports and signal ports Immunity, enclosure ports Immunity, input AC power port Immunity, input DC power port The type of interfering signals, level of tests etc. depends on the standa ..read more

EMC or we can say ‘Electromagnetic Compatibility’ is the strength of an electronic device to resist the interference if any by other electronic devices and to exist within an environment without causing any interference of itself.  EMC Testing can be divided into two main categories which are: Emission Testing: Electromagnetic disturbances caused by an electronic device can result in the interference or malfunctioning of another electronic device present in the same environment. This is referred to as ‘Electromagnetic Interference’ or EMI. Susceptibility or Immunity Testing: Immunit ..read more

To ensure your product passes through the EMC compliance, the EMC Testing should be conducted in various stages of the life of the product. Breaking the EMC Test into different stages is useful as the requirements of each stage differ slightly from each other. Stages of EMC Testing There are 4 stages of EMC Testing: Development Test Pre-Compliance Test EMC Compliance Test Production Test Development Stage In this first stage, it is easy to make changes to an electronic circuit design. In this way, tests can be conducted to ensure that best EMC/EMI performance is obtained. Tests at this stag ..read more
