Best Practices by Leading Anechoic Chamber RF Testing Labs

Before Testing: Preparation and Planning

RF Safety Compliance Criteria
Collaborative Test Consultation
  • Engage with clients early to fully understand their device's intended application, design, and compliance goals.
  • Completion of an online product questionnaire is a critical step in developing appropriate test plans. Having manufacturers provide complete and accurate information helps define and streamline the compliance goals.
  • The product questionnaire is the foundation of the development of a customized testing plan tailored to the device's operational environment and the target market.
  • Provide clients with a checklist of preparatory steps, including proper firmware configurations, antenna setup, and documentation requirements.
Environmental and Equipment Calibration
  • Regularly calibrate all testing equipment, such as spectrum analyzers, signal generators, and measurement antennas, to ensure compliance with ISO/IEC:17025 standards.
  • Verify the anechoic chamber’s performance by measuring its shielding effectiveness and absorber efficiency. Conduct regular chamber validation using test fixtures and reference emitters.
Comprehensive Device Inspection
  • Conduct a thorough review of the device's technical documentation, including schematics, block diagrams, and antenna specifications, to identify potential compliance risks that may have changed during the initial review.
  • Inspect the physical device for design flaws that might lead to unintentional emissions, such as poorly shielded cables or improper antenna placement.

During Testing: Precision and Efficiency

RF Safety Compliance Criteria
Dynamic Real-Time Monitoring
  • Use a cloud-integrated testing platform, like MiTest®, to provide real-time monitoring of testing progress and results. This allows clients to remotely access data, identify issues quickly, and make real-time adjustments.
  • Monitor environmental conditions within the chamber (e.g., temperature, humidity) to maintain a consistent and controlled testing environment.
Automated and Repeatable Testing Protocols
  • Leverage automated turntables and antenna positioning systems to measure emissions and immunity across all required angles and polarizations, ensuring complete coverage.
  • Implement repeatable testing protocols for precise measurements, reducing variability between test cycles and improving confidence in results.
Comprehensive Testing Across Multiple Scenarios
  • Test devices under worst-case operational conditions, such as maximum power output or continuous transmission, to evaluate peak emissions and immunity performance.
  • Simulate real-world interference scenarios using controlled signal injections, particularly for devices operating in crowded RF environments (e.g., Wi-Fi, Bluetooth, or IoT devices).

After Testing: Reporting and Support

RF Safety Compliance Criteria
Detailed and Actionable Reporting
  • Provide clients with comprehensive test reports that include:
    • Graphical representations of emissions and immunity performance.
    • Antenna patterns, gain, and efficiency data.
    • Recommendations for addressing compliance gaps or optimizing device performance.
  • Tailor reports to meet the submission requirements of specific regulatory bodies, simplifying the approval process for clients.
Post-Test Consultation and Iterative Improvement
  • Offer a post-test debrief to discuss results, answer questions, and provide actionable guidance for redesigns or adjustments needed to pass compliance tests.
  • Support clients in iterative testing by prioritizing retests for modified devices, minimizing time-to-market delays. Share insights on emerging regulatory trends or advanced testing techniques.

Frequently Asked Questions about Anechoic Chambers and RF Testing

What is the purpose of an anechoic chamber in RF testing?

Anechoic chambers are designed to provide a controlled environment free from external electromagnetic interference and internal reflections. This allows for precise measurements of radiated emissions, immunity, and antenna performance, ensuring that devices meet regulatory standards and function reliably in real-world conditions.

At MiCOM Labs, we maintain ISO/IEC:17025 accreditation, regularly calibrate our equipment, and validate our chambers to meet stringent performance standards. Automated turntables, precise positioning systems, and standardized testing protocols ensure repeatable results across all measurements.

Yes, our advanced anechoic chambers are equipped to handle 5G or mmWave frequencies, making them ideal for testing high-frequency applications and other advanced wireless communication systems. While most IoT devices operate in sub-6 GHz frequencies, our chambers can accommodate testing for high-frequency IoT use cases in specialized applications.

Preparing your device involves several key steps:

  • Ensuring the firmware supports continuous transmission or fixed channel modes.
  • Selecting and positioning antennas according to regulatory requirements.
  • Providing schematics, technical specifications, and any relevant test documentation.
  • Collaborating with our team for a pre-test consultation to address potential compliance issues beforehand.

The testing timeline varies depending on the complexity of the device, the number of frequency bands tested, and regulatory requirements. On average, testing takes 1-5 days. Factors such as the need for retesting or custom protocols can extend this duration, our protocols minimizes delays by automating and streamlining the process.

Absolutely. MiCOM Labs provides comprehensive support for regulatory certification, including detailed test reports, technical documentation, and direct communication with certification bodies. We streamline the submission process to help you achieve market access quickly.

Yes, if your device fails, our engineers can conduct a detailed gap analysis to identify the root cause. We provide actionable recommendations for redesigns or adjustments and offer expedited re-testing to minimize time-to-market delays.
