Professional Radiated Emission Testing for Electronic and Electrical Products
PRIDE TESTING LAB provides Radiated Emission Testing in Delhi NCR for manufacturers, OEMs, product developers, importers, technology companies, and organizations developing electrical and electronic equipment.
Electronic devices can unintentionally generate electromagnetic energy that travels through the surrounding environment. When these emissions exceed the limits specified in the applicable standard, they may create electromagnetic interference with other equipment or communication systems. Radiated emission testing is used to measure and evaluate these unwanted electromagnetic disturbances under defined test conditions.
Radiated emission measurement methods and test facilities are addressed within the CISPR 16 series, while the applicable emission limits depend on the relevant product or industry standard. Government testing facilities in India list radiated emission testing against standards including CISPR 11, CISPR 14-1, CISPR 15 and CISPR 32, among others.
If you are looking for a Radiated Emission Testing Lab in Delhi NCR, PRIDE TESTING LAB can help you understand your product’s testing requirements and determine an appropriate test scope based on the product category, intended application, applicable standard, operating configuration, and compliance objective.
What Is Radiated Emission Testing?
Radiated emission testing is an EMC evaluation used to measure electromagnetic energy unintentionally emitted by an electrical or electronic product into the surrounding environment.
These emissions may originate from:
- Digital circuits
- Switching power supplies
- Oscillators and clocks
- Microprocessors
- Motors and drives
- High-frequency circuits
- Communication modules
- Printed circuit boards
- Internal wiring
- External cables and connected interfaces
The product is operated in defined configurations while its electromagnetic emissions are measured using the appropriate test setup, equipment, antennas, measurement procedures, frequency range, and detector settings required by the applicable standard.
Radiated disturbance measurement methods are covered by CISPR 16-2-3, while antennas and test sites are addressed by CISPR 16-1-4. The specific version and requirements used for a project should be confirmed against the applicable product standard.
Why Is Radiated Emission Testing Important?
Electronic and electrical equipment increasingly operates near other electronic systems, wireless devices, communication equipment, industrial controls, and sensitive instruments.
Unwanted electromagnetic emissions may potentially affect nearby equipment. Radiated emission testing can therefore help organizations evaluate the electromagnetic disturbance generated by a product.
Testing may support:
- Product development
- Design validation
- Pre-compliance evaluation
- Formal compliance testing
- Customer qualification requirements
- Market access planning
- Product performance investigation
- Identification of potential emission concerns
The exact compliance requirement depends on the product and the applicable regulatory, industry, or customer specification.

Medical electrical equipment can have product-specific EMC requirements. Radiated emission evaluation may form part of the overall electromagnetic compatibility assessment.
Automotive Electronics
Automotive electronic components and systems may require evaluation according to applicable automotive EMC requirements.
Railway and Transportation Equipment
Electronic equipment used in railway and transportation applications may be subject to industry-specific EMC requirements.
Measurement and Control Equipment
Laboratory instruments, sensors, measurement systems, and electronic control equipment may require radiated emission testing depending on their applicable product standards.
How Radiated Emission Testing Works
The exact procedure depends on the applicable standard, but a typical testing process may involve the following stages.
1. Product and Requirement Review
The product type, model, intended application, operating environment, target market, and applicable standard are reviewed.
2. Identification of Test Configuration
The product configuration is defined, including:
- Power supply arrangement
- Cables
- Connected accessories
- Supporting equipment
- Communication interfaces
- Operating modes
- Software or firmware conditions
The test configuration is important because electromagnetic emissions can vary according to how the equipment is installed and operated.
3. Test Setup
The equipment under test is installed according to the relevant test procedure.
Depending on the applicable standard and test requirement, radiated emission testing may involve an appropriate test site or chamber and relevant measuring equipment, antennas, antenna positioning, and measurement arrangements.
CISPR 16 publications address measurement apparatus, antennas, test sites, and methods used for radiated disturbance measurements.
4. Product Operation
The equipment is operated in relevant modes that are appropriate for the applicable test requirements.
5. Emission Measurement
Electromagnetic emissions are measured over the applicable frequency range using the relevant procedures and equipment.
The frequency range and measurement method depend on the applicable standard and product.
6. Result Evaluation
The measured results are evaluated against the relevant limits or requirements specified for the product and test configuration.
7. Test Documentation
Relevant measurements, observations, configurations, and results are documented according to the agreed testing and reporting requirements.
Factors That Can Affect Radiated Emissions
Radiated emission levels can be influenced by many aspects of product design and operation.
Common factors may include:
- PCB layout
- Switching frequency
- Clock frequency
- Cable length
- Cable routing
- Grounding arrangement
- Shielding
- Enclosure design
- Power supply design
- Operating mode
- Connected peripherals
- Communication interfaces
For this reason, a product should be tested in the appropriate configuration required by the applicable standard or agreed test plan.
Radiated Emission Pre-Compliance Testing
Radiated emission pre-compliance testing can be useful during product development.
Instead of waiting until the final development stage, engineering teams may evaluate a prototype or pre-production product to identify potential electromagnetic emission concerns earlier in the development process.
Pre-compliance evaluation may help investigate:
- Unexpected emission peaks
- Frequency-specific emission concerns
- Cable-related emissions
- Power supply-related emissions
- Clock and switching noise
- Differences between operating modes
- Potential areas requiring engineering review
Pre-compliance testing should not be represented as a substitute for formal testing when a regulatory, certification, contractual, or customer requirement requires testing according to a specific procedure.
Radiated Emission Testing vs Conducted Emission Testing
Radiated emission and conducted emission testing evaluate different paths through which electromagnetic disturbances may travel.
Radiated Emissions
Radiated emission testing evaluates electromagnetic energy emitted from the equipment into the surrounding environment.
Conducted Emissions
Conducted emission testing evaluates disturbances travelling through conductive paths such as:
- Power lines
- Signal cables
- Communication connections
- Other applicable electrical interfaces
Depending on the applicable product standard, a complete EMC evaluation may require one or both types of emission testing, along with applicable immunity testing.
