Nowadays, modern electronic devices should comply with the strict EMC requirements before being put on the market. From automotive electronics, aerospace systems, to telecommunications, EMC Testing is used by companies in order to identify electromagnetic interference and check products’ performance.
Custom-Built EMC Test Chambers are the solution for companies with specific testing requirements. Different from regular chambers, custom chambers can be built considering the size of the tested product, frequency range, required testing standards, equipment, available space, and future needs.
What Are Custom-Built EMC Test Chambers?
Emc Test Chambers Designed Especially For Emc Testing Are Engineered Environments That Provide Certain Conditions Required For Carrying Out Tests. The Design Of Chambers Can Include Many Components Such As Shielding According To Your Requirements, RF Absorbers, Filtered Power, Ventilation System, Doors, Cables, Antennas, Turntable, Etc.
The Main Advantage Of Customized Test Chambers Is Flexibility. In Other Words, Rather Than Conducting Tests According To Standard Chambers, You Can Design Your Chamber According To Test Requirements.
Designing Based on Specific Application
Each testing laboratory has specific demands. For instance, an electronic gadget will need a small chamber, whereas bigger automobiles or aeronautical gadgets will require a large testing chamber.
A customized chamber can be constructed depending on:
- Size of the product
- Frequency requirement
- Distance required for testing
- Arrangement of the testing equipment
- Antennas placement
- Turntable requirement
- Laboratory space available
- Future testing demand
Enhanced EM Shielding Capability
EMC Compliance Testing requires effective electromagnetic shielding. Ineffective shielding can lead to errors due to influence by external electromagnetic sources. Also, any unintended emissions from the testing chamber will interfere with the process.
A customized chamber will provide suitable EM shielding panels, doors, filters, grounding, and cabling systems.
Improved Control of RF Reflections
In-house reflections may affect electromagnetic measurements. Custom-made EMC Testing Chambers will utilize appropriate RF absorbing materials in accordance with the specific frequency range.
The choice of ferrite tiles, foam absorbers and hybrid absorbing system can be made depending on the application. Proper installation of absorbers can contribute to the improvement of the testing conditions.
Effective Utilization of Available Space
Available laboratory space can be expensive and scarce. Not always can a conventional chamber fit appropriately within the facility.
A custom solution can be designed taking into consideration such features as the dimensions of the room, structural constraints, access paths, ceiling height, equipment requirements, etc. Thus, companies can take advantage of all available space while preserving the testing functionality.
Convenient Equipment Installation
Modern EMC facilities may contain various elements such as antennas, receivers, amplifiers, turntables, monitoring systems, power filters and control equipment.
When using a custom-made chamber, the installation of equipment can be taken into account at the design stage. Proper wiring, equipment accessibility and other elements can make testing more effective and avoid future expenses on modifications.
Standard EMC Chamber vs Custom EMC Chamber
| Feature | Standard Chamber | Custom Chamber |
|---|---|---|
| Design flexibility | Limited | High |
| Space utilization | General | Optimized |
| Equipment integration | Standard | Customized |
| Testing configuration | Fixed | Application-specific |
| Future expansion | Limited | Easier to plan |
Facilitates Future Testing Needs
The technology is still changing, and it keeps developing, giving rise to the need for new technologies in EMC, EMI, RF, and wireless testing. It is possible to consider future needs when designing a custom chamber.
When planning the design, one should take into account the possibility to use bigger products, extra equipment, new frequency ranges, and other future testing needs.
Pro Tip:
Do not plan an EMC chamber for today only. Take into account future product sizes, frequencies, extra equipment, and testing needs before building the chamber.
Increased Testing Consistency
The controlled testing environment is crucial for the consistency of results. Proper shielding, absorber positioning, equipment location, and test geometry will enable laboratories to have the same testing conditions.
This way, one will be able to develop products since engineers will be able to compare different designs and detect electromagnetic issues.
Custom-Built EMC Test Chambers are flexible and useful because of better use of space, efficient shielding, proper equipment installation, and testing in the future. These chambers are very helpful for manufacturing companies and laboratories dealing with special products or EMC requirements.
If one needs EMC, EMI, RF, and compliance testing capacities, custom chamber will be a better choice.
