EMI/EMC Testing Services

Expert EMI/EMC Testing and Electromagnetic Compatibility Solutions

PRIDE TESTING LAB provides professional EMI/EMC testing services for manufacturers, OEMs, product developers, importers, exporters, and technology companies developing electrical and electronic products.

Modern electronic products operate in increasingly complex electromagnetic environments. A product must not only control the unwanted electromagnetic disturbances it produces, but it may also need to continue operating as intended when exposed to disturbances from other equipment and sources.

Our EMI/EMC testing services support product evaluation for emissions, immunity, electromagnetic compatibility, product reliability, pre-compliance assessment, and applicable market-access requirements.

Depending on the product category and target market, the applicable testing programme may include standards and requirements associated with IEC, CISPR, EN, FCC, MIL-STD and other product-specific standards.

The exact standard, test setup, operating mode and acceptance criteria should always be selected according to the product and applicable regulatory or customer requirement.

What Is EMI/EMC Testing?

Understanding EMI

EMI stands for Electromagnetic Interference.

Electronic and electrical products can generate unwanted electromagnetic energy during normal operation. If this energy exceeds applicable limits, it can potentially interfere with the operation of nearby equipment.

EMI testing evaluates electromagnetic disturbances that may be emitted through:

• Air
• Power lines
• Signal cables
• Communication cables
• Other electrical connections

Common EMI evaluation areas include:

• Radiated Emission
• Conducted Emission
• Harmonic-related requirements, where applicable
• Voltage fluctuation or flicker-related requirements, where applicable

Understanding EMC

EMC stands for Electromagnetic Compatibility.

Electromagnetic compatibility generally involves two important aspects:

1. A product should not create unacceptable electromagnetic disturbance.
2. A product should have an appropriate level of immunity to electromagnetic disturbances in its intended environment.

EMC testing may therefore include both:

Emission Testing

To evaluate electromagnetic energy emitted by the equipment.

Immunity Testing

To evaluate how the equipment performs when exposed to specified electromagnetic disturbances.

A successful EMC design considers the product, its cables, power connections, installation configuration, operating modes and intended electromagnetic environment.
