EMC Testing for Audiovisual, IT and Multimedia Equipment
Audio, video, IT and multimedia products combine fast digital circuitry, switching power supplies, cables and increasingly wireless connectivity. Stancer Testing-Lab helps manufacturers evaluate the electromagnetic emissions and immunity of these products, with a test plan built around their functions and intended markets.
Our ISO/IEC 17025-accredited EMC and RF laboratory uses Rohde & Schwarz instrumentation and automated measurements to support development investigations and formal testing. We work with your engineers to select representative configurations, monitor product performance and document the results.
Use our EMC testing service for emissions and immunity planning. Products with Bluetooth, Wi-Fi or other transmitters may also need RF and wireless testing. Applicable standards, editions, equipment classes and accredited methods are confirmed before the program begins.

Products and Configurations We Help Evaluate
The complete system matters: its power adapter, connected peripherals, cables, accessories and software can change the EMC result. We plan around the configurations you intend to supply.
IT and digital systems
Computers, peripherals, digital controllers and data-processing equipment, including representative interfaces and connected support equipment.
Displays and multimedia products
Displays, media systems and integrated AV products, evaluated with documented screen activity, signal paths and accessories.
Connected electronics
Radio-enabled multimedia and IT products, with EMC and wireless measurements coordinated around the antenna and operating configuration.
Prepare a representative test configuration
- Define the requirementsIdentify target markets, product functions, intended environment and equipment class.
- Configure the systemSelect cables, adapters, peripherals and software that represent the supplied product.
- Exercise and monitorAgree operating modes and how audio, video, communications and other functions will be observed.
- Document the evidenceRecord the tested setup, results and any changes made during the evaluation.
Plan Emissions, Immunity and Wireless Evaluation
Emissions, immunity and radio requirements answer different questions. The correct combination depends on the product, its functions and where it will be marketed.
| Reference | Purpose in the test plan |
|---|---|
| CISPR 32 / EN 55032 | Multimedia equipment emissions requirements, including the applicable Class A or Class B limits. |
| CISPR 35 / EN 55035 | Multimedia equipment immunity requirements, with performance monitored during the relevant disturbances. |
| FCC Part 15 Subpart B | U.S. requirements for applicable unintentional radiators, including digital equipment. The authorization route depends on device type. |
| ICES-003 | Canadian emissions and associated administrative requirements for applicable IT equipment and digital apparatus. |
| Applicable radio requirements | Additional FCC, ISED or ETSI requirements may apply when the product includes an intentional transmitter. |
These references guide the review; they do not replace checking the product-specific requirements and current editions. See our FCC testing, ISED testing and CE marking support pages for market-specific planning.
Before booking, complete the EMC and RF Client Information Sheet and review our accreditation information with the proposed test methods.
What is the difference between CISPR 32 and CISPR 35?
CISPR 32 addresses electromagnetic emissions from multimedia equipment. CISPR 35 addresses immunity: how the equipment performs when exposed to electromagnetic disturbances. A product may need both emissions and immunity evaluation for its intended market. We confirm the applicable editions and requirements during test planning.
How do we select Class A or Class B emissions limits?
The classification depends on the applicable standard and intended use environment. Class B limits are generally associated with residential use and are more restrictive than Class A limits. Share where the product will be used and marketed so that the classification, operating modes and representative configurations can be agreed before testing.
Does a Wi-Fi or Bluetooth product need testing beyond multimedia EMC?
It may. CISPR multimedia evaluations address emissions and immunity, while an intentional transmitter can introduce separate radio requirements. Module approval, antenna choices and integration conditions should be reviewed for the finished product. Our RF and wireless testing team can coordinate the relevant measurements with the EMC program.
Can we investigate EMC issues before the final product is ready?
Yes. EMC pre-compliance testing can focus on a suspected noise source, an immunity response or a proposed cable, filter or enclosure change. Bring representative power supplies, peripherals, firmware and monitoring tools. These sessions provide design feedback; a pre-compliance result does not guarantee a later compliance pass.
