EMC Testing Matters

Preservation of the electromagnetic spectrum

We rely on a finite electromagnetic spectrum for radio, wireless communications, satellite navigation, and more. Even unintended emissions from electronic circuits can pollute these frequencies, causing cross-interference.

Safety in Critical Systems

Failures in devices due to EMI can cause serious harm, especially in sectors like medical, military, automotive, and aerospace. EMC standards are built to safeguard the performance of safety-critical equipment.

Product Performance and Reliability

EMC issues can degrade sensitive electronics, from sensor readings to wireless signals. Thorough EMC testing helps identify and resolve interference sources early—improving product reliability and reducing returns.

Regulatory Compliance & Legal Risk

Regulators such as the FCC (US), CE (EU), ISED (Canada), and others enforce EMC standards. Non-compliance can lead to fines, product recalls, and even bans on market entry.

Market Access & Customer Trust

Passing EMC tests ensures smoother certification and faster time-to-market. It demonstrates professionalism and builds trust with distributors and customers worldwide.

Main types of EMC testing

Radiated Emissions (EMI) tests
Radiated emissions testing measures the electromagnetic field strength of the emissions unintentionally produced by the electrical product. These emissions are inherent to the currents and switching voltages within any digital circuit.

Conducted Emission tests
Conducted emissions testing measures the portion of electromagnetic energy created by a product and conducted onto the power supply cord. The test aims to verify that these emissions comply with specified limits in relevant EMC standards, usually from 150 kHz to 30 MHz.

Flicker tests
Flicker testing is another form of emissions testing. It helps determine if the product sample produces fluctuating load in the branch circuit causing RMS voltage fluctuations with flickers.

Radiated RF electromagnetic immunity tests
The radiated RF electromagnetic immunity test measures the performance of the product's immunity to radiated RF electromagnetic field disturbances for simulating the interference of transmitted electromagnetic waves.

Electrostatic discharge immunity tests
This form of EMC testing evaluates the performance of the immunity to electrostatic discharges at the enclosure, accessible ports and other similar areas of the product sample.

Surge immunity test
Surge immunity testing evaluates the performance of the equipment's immunity to surge disturbances. Three pieces of equipment are needed to perform this test – surge wave generator, coupling/decoupling network and reference ground plane.

Magnetic field immunity test
This form of EMC testing measures the performance of the immunity of an electrical product to magnetic field disturbances.

Electrical fast transient (EFT) immunity test
This test helps evaluate the performance of the product's immunity to electrical fast transient disturbances.

FAQ

Q: Can the fee be paid after the Environmental reliability testing is completed?

A: Yes. However, the fees must be paid before obtaining the report.

Q: Can the customer watch the test process on site?

A: Yes. You can fill in the relevant application form to make an appointment.

Q: If the test results are not qualified, can you help to debug the equipment and make the test results become qualified?

A: Yes. However, it belongs to the new business type, the specific needs to confirm with the customer service and engineers.

Q: What is the EMC effect of electronics?

A: ElectroMagnetic Compatibility (EMC) is a characteristic of electrical and electronic equipment that permits it to operate as intended in the presence of other electrical and electronic equipment, and not to adversely interfere with that other equipment.

Q: What instrument is used to measure EMC?

A: A spectrum analyzer or EMI receiver are useful pieces of test hardware to perform emissions testing. For EMC testing, it is important for the spectrum analyzer to have a quasi-peak detector feature, which is often an optional extra, and the appropriate resolution bandwidth (RBW) to match EMC measurement standards.

Q: What is the purpose of EMC testing?

A: Electromagnetic compatibility (EMC) testing measures the ability of equipment or systems to function satisfactorily in their electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment.
