Emc test raporu8/10/2023 ![]() These short bursts of energy can cause a number of problems, such as IC port damage, communication failures, damage to LCD screens and more.ĮSD testing is performed with EMC test equipment that creates a short burst of energy, typically at 4kV and 8kV. Electromagnetic noise can come from a variety of sources, from cellphones and microwaves to Wi-Fi routers.Įlectrostatic discharge (ESD) refers to electric shockselectrostatic discharges (carpet shocks) which occur as a result of built-up static electricity. Radiated immunity testing evaluates the ability of a device to function normally when exposed to different electrical field sources. Several different types of EMC test equipment can be used to do this, including CDNs, BCI probes and direct voltage injection equipment. Surge simulation requires the use of specialized EMC test equipment to confirm that the appropriate protective circuitry is installed, ensuring there will be no liability issues when your product goes to market.Ĭonducted immunity testing involves simulating potential disturbances from other devices powered by the same power network, or inductively coupled onto its I/O lines. For compliance and reliability purposes, it is essential to properly protect against the effects of a low-frequency power surge on many consumer goods.Įven a momentary power surge can lead to arcing, cabling breakdowns, motor damage and a number of other problems. Voltage drop testing is also used to test a device's ability to successfully reboot following a complete power outage.Įlectromagnetic surges can be caused by a number of factors, including indirect lightning strikes and routine power switching events. In a voltage drop test, a tapped autotransformer and immunity test system will run a series of simulations featuring dips and dropouts of varying lengths and severities. This replicates the effects of brownouts, as well as the normal fluctuations in the AC mains network that a device may experience. ![]() ![]() Typical devices requiring this type of immunity testing include CRT monitors, electrodynamic microphones and more.Īs the name implies, voltage drop testing tests the impact of a sudden voltage dip or other power interruption on a piece of equipment. Magnetic field testing uses EMC test equipment to simulate the effects of a magnetic field and ensure a device continues to operate properly. Here we’ll look at seven of the most commonly used methods. Because there is a wide range of potential EM phenomena, multiple types of immunity testing exist. This is important for consumer goods sold internationally, as well as for military, medical, avionics and other specialized products. EMC immunity testing measures the ability of a device to withstand different types of electromagnetic phenomena.
