Radiated Emission Test

Radiated emission testing is a crucial aspect of product development for electronic devices. It involves measuring the amount of electromagnetic energy that is emitted from the device and comparing it to regulatory limits.

In today’s world, electronic devices have become an indispensable part of our lives, and their electromagnetic compatibility (EMC) is crucial. Radiated emission test is an important aspect of EMC testing that ensures that electronic devices do not cause any harmful interference with other devices. In this blog, we will discuss what a radiated emission test is, why it is necessary, industry standards to follow during testing, testing procedure, and why Pride Testing Labs is the best choice for radiated emission testing.

What Is A Radiated Emission Test?

Radiated Emission Testing

Radiated emission test is a type of EMC testing that evaluates the level of electromagnetic energy radiated by an electronic device. The test is conducted to ensure that the electromagnetic energy emitted by the device is within the acceptable limits set by regulatory agencies such as the Federal Communications Commission (FCC).

Why Is a Radiated Emission Test Necessary?

Radiated emission testing is necessary for several reasons, such as:

  • Ensuring electromagnetic compatibility of electronic devices with other devices.
  • Complying with regulatory requirements such as FCC regulations.
  • Avoiding interference with other electronic devices such as medical equipment and aircraft.
  • Identifying and resolving issues related to electromagnetic interference.
  • Ensuring the safety of people and equipment by preventing harmful interference.

Industry Standards To Follow During Testing

The following are the industry standards that must be followed during radiated emission testing:

  • FCC Part 15: This standard is applicable for electronic devices operating at frequencies of up to 1 GHz.
  • CISPR 22: This standard is applicable for information technology equipment.
  • MIL-STD-461F: This standard is applicable for military equipment.
  • EN 55032: This standard is applicable for multimedia equipment.
  • ANSI C63.4: This standard is applicable for radiated emission measurement procedures.

Testing Procedure

The radiated emission test procedure involves the following steps:

  • Set up the Test Equipment: The first step in the radiated emission test procedure is to set up the test equipment. This equipment includes antennas, spectrum analyzers, amplifiers, and other necessary devices to measure the radiation from the DUT.
  • Configure the Device Under Test: Once the test equipment is set up, the next step is to configure the DUT. The DUT should be in a steady state, and all its components should be functioning correctly.
  • Measure the Radiated Electromagnetic Energy: After configuring the DUT, measure the radiated electromagnetic energy from the device using the test equipment. The antennas are used to capture the electromagnetic radiation, and the spectrum analyzers are used to measure the frequency and intensity of the radiation.
  • Compare the Measured Values with the Regulatory Limits: The measured values are then compared with the regulatory limits set by the governing bodies. If the measured values are within the regulatory limits, the device is considered to have passed the test. However, if the measured values exceed the regulatory limits, the device needs to be modified to reduce the amount of radiation emitted.
  • Identify any Issues Related to Electromagnetic Interference: During the test, any issues related to electromagnetic interference are identified. These issues may include problems with the DUT’s components, design flaws, or interference from other devices. Once identified, appropriate actions are taken to resolve the issues and retest the device.

Overall, the radiated emission test procedure is critical to ensure that electronic devices do not interfere with each other and operate within the regulatory limits. By following the industry standards and testing procedures, manufacturers can ensure that their devices meet the necessary requirements and do not cause any unwanted electromagnetic interference.
