EMI and EMC Testing

Ensure the Reliability of Your Products

EMI and EMC testing are crucial steps in ensuring that electronic devices meet regulatory requirements for electromagnetic compatibility. EMI (electromagnetic interference) refers to any disturbance in the electromagnetic field that affects the performance of an electronic device. EMC (electromagnetic compatibility) refers to the ability of an electronic device to operate without interference in its intended electromagnetic environment.

In today’s world, where electronic devices are becoming more complex and interconnected, EMI and EMC testing have become even more important. Failure to meet regulatory requirements can result in costly delays and product recalls, damage to brand reputation and even safety hazards.

What is EMI Testing?

EMI testing stands for Electromagnetic Interference Testing which is a type of testing that is used to evaluate the ability of electronic devices and systems to operate without causing or being affected by unwanted electromagnetic interference (EMI). EMI can occur when electromagnetic energy from one device interferes with the operation of another device, leading to various issues such as distorted signals, data loss and malfunction.

EMI testing is typically performed to ensure that electronic devices and systems comply with regulatory requirements, such as FCC, CE, CISPR and IEC standards.

What is Radiated EMI Testing?

This type of testing evaluates the amount of electromagnetic energy that is radiated by a device or system into the surrounding environment. The test measures the field strength of the radiated energy at different frequencies and distances from the device.

What is Conducted EMI Testing?

This type of testing evaluates the amount of electromagnetic energy that is conducted through power and signal cables connected to a device or system. The test measures the amount of unwanted noise that is conducted along the cables.

What is Transient EMI Testing?

This type of testing evaluates the ability of a device or system to withstand sudden changes in voltage or current that can cause electromagnetic interference. The test measures the susceptibility of the device or system to transient events such as lightning strikes or power surges.

What is Magnetic EMI Testing?

This type of testing evaluates the ability of a device or system to withstand sudden changes in voltage or current that can cause electromagnetic interference. The test measures the susceptibility of the device or system to transient events such as lightning strikes or power surges.

Overall, EMI testing is an essential process that ensures electronic devices and systems can operate effectively in the presence of electromagnetic interference.

What is EMC Testing?

EMC testing stands for Electromagnetic Compatibility Testing. It is a type of testing that evaluates the ability of electronic devices and equipment to operate properly in their intended electromagnetic environment and not interfere with other nearby devices or equipment.

EMC testing can be divided into two main categories: emissions testing and immunity testing.

  • Emissions Testing
  • Immunity Testing

What is Emissions Testing?

This type of testing measures the amount of electromagnetic energy that is emitted from a device and ensures that it does not exceed the legal limits. Emissions testing is done in a shielded room or anechoic chamber and measures the radiated and conducted emissions from the device.

What is Immunity Testing?

This type of testing evaluates how well a device can function in the presence of electromagnetic interference (EMI) from other sources. Immunity testing is also done in a shielded room or anechoic chamber and involves subjecting the device to various electromagnetic fields to see if it continues to function properly.

There are various types of EMC testing that fall under emissions and immunity testing. Some of the most common types include:

Radiated Emissions Testing: This tests the amount of electromagnetic energy that is emitted by the device and radiated through the air.

Conducted Emissions Testing: This tests the amount of electromagnetic energy that is emitted by the device and conducted through its power and signal cables.

Radiated Immunity Testing: This tests how well the device can function in the presence of electromagnetic energy that is radiated through the air.

Conducted Immunity Testing: This tests how well the device can function in the presence of electromagnetic energy that is conducted through its power and signal cables.

Electrostatic Discharge (ESD) Testing: This tests the device’s ability to withstand electrostatic discharge, which can damage electronic components.

Transient Immunity Testing: This tests the device’s ability to function in the presence of transient voltages or currents, which can occur during power surges or lightning strikes.

Overall, EMC testing is crucial for ensuring that electronic devices and equipment can function properly and coexist with other devices in their electromagnetic environment.

Types of Emission Testing

Radiated Emissions (RE)

It is a radiated test that measures the level of Electromagnetic Interference (EMI) a device generates and radiates while it is operational at its normal and it confirms whether the emissions level is within the specified limits.

Conducted Emissions (CE)

It is a conducted test that measures the level of Electromagnetic noise the device is generating and while it is operational at its normal the same noise might travel along the cable or I/O lines and cause interference to the other systems.

Types of Immunity Testing

Radiated Susceptibility (RS)

It is a radiated test that validates the EUT, how well the EUT performs when exposed to the level of radiated electromagnetic noise it will encounter in its expected operating environment.

Conducted Susceptibility (CS)

It is a conducted test that validates the EUT, how well the EUT performs or reacts to the electromagnetic noise generated from another source device and while the same noise may enter the EUT through the cable or I/O lines.
