EMC & EMI Compliance Support

Understanding EMC and EMI

Electromagnetic compatibility (EMC) and electromagnetic interference (EMI) relate to how electronic devices behave in environments where multiple electronic systems operate near each other. EMC means a device can function as intended without causing interference or being disrupted by other equipment, while EMI refers to unwanted electromagnetic energy that can affect device performance.

Ensuring products are EMC and EMI compliant is a critical part of preparing them for global markets.

    How VPI Can Help You Prepare for EMC & EMI Requirements

    VPI Technology no longer performs full EMC or EMI compliance testing in-house. However, we continue to support clients with early-stage evaluations, design guidance, and assistance in coordinating with third-party laboratories that perform formal compliance testing.

    Pre-Scan Evaluations

    Our team offers pre-scan testing in our anechoic chamber located in Draper, Utah. These evaluations give early insight into potential emissions or interference issues before engaging with an external test lab. Pre-scan results can help reduce redesign cycles and improve your readiness for accredited testing.

    Design & Compliance Guidance

    Based on years of experience in electronic product development, VPI’s engineers can help you interpret EMC/EMI considerations within your design. This includes advising on common emission sources, mitigation strategies, and documentation best practices, so your product is better prepared for formal testing.

    Coordinating Third-Party Testing

    Formal compliance testing, performed by accredited third-party laboratories, is typically required to demonstrate conformance with regulatory standards before products can be marketed in many regions. VPI supports clients by:

      • Clarifying applicable EMC/EMI regulatory and standard requirements

      • Preparing design documentation and test plans

      • Providing recommendations for qualified external test labs

    Why EMC & EMI Planning Matters

    Identifying and addressing EMC and EMI issues early in the product development cycle helps reduce costly iterations, shortens time to market, and improves overall product reliability. Early planning ensures problems are discovered sooner and mitigated efficiently.

    Let’s Get Started

    If you’re preparing a product that must meet EMC or EMI requirements, VPI Technology can help evaluate design readiness, schedule a pre-scan evaluation, or plan the path to accredited third-party compliance testing.

    Frequently Asked Questions

    What is the difference between a pre-scan and formal EMC or EMI testing?

    A pre-scan is an early evaluation used to identify potential EMC or EMI issues during development. Formal compliance testing is performed by an accredited third-party laboratory and is required for certification. Pre-scans help reduce risk before formal testing begins.

    Does VPI perform EMC or EMI compliance testing in-house?

    No. VPI no longer performs formal EMC or EMI compliance testing or certification in-house. We provide pre-scan evaluations, compliance-aware design guidance, and support to help clients prepare for third-party testing.

    Can VPI help us find a testing laboratory?

    Yes. VPI can recommend qualified third-party testing laboratories and help you understand what testing may be required based on your product and target market.

    When should EMC and EMI considerations be addressed?

    EMC and EMI considerations should be addressed early in the design process. Planning ahead can help avoid redesigns, delays, and added costs later in development.

    Do all electronic products need EMC or EMI testing?

    Many electronic products require some level of EMC or EMI evaluation, depending on how they operate and where they will be sold. VPI can help clarify which requirements may apply to your product.
