Compatible Electronics

Pre-Compliance EMC Testing & Consulting

Pre-Compliance & EMC Consulting Services

Compatible Electronics offers a complete suite of pre-compliance testing, design review, troubleshooting, and EMC consulting services — all grounded in 40+ years of hands-on compliance testing experience and delivered from the same NVLAP accredited laboratory infrastructure used for formal certification. Testing and consulting under one roof, at three Southern California locations.

The Testing + Consulting Advantage

The most valuable aspect of Compatible Electronics' pre-compliance and consulting services is that they are delivered by the same engineers who run formal NVLAP accredited compliance tests in our CISPR chambers every day. Our consultants know what the test equipment actually measures, which design patterns consistently fail specific tests, and which regulatory interpretations are accepted by FCC and EU market surveillance authorities in practice — not just in theory.

This direct connection between engineering consulting and accredited testing means that every recommendation we make can be immediately validated by pre-compliance testing at the same location, and that the path from early-stage consulting through pre-compliance work to formal certification is seamless — same lab, same engineers, same equipment throughout.

🔬

Lab-Grounded Advice

Recommendations based on direct observation in our NVLAP accredited test chambers — not textbook theory.

🔄

Seamless Consulting-to-Certification Path

From design review through pre-compliance to formal ILAC-MRA recognized certification — same location, same engineers.

Immediate Fix Validation

Consulting recommendations validated by pre-compliance testing on the same day at the same Southern California location.

🌍

Multi-Market Expertise

FCC, CE marking, ISED Canada, RCM, VCCI, KC — compliance strategy grounded in real accreditation experience across all major markets.

Pre-Compliance & Consulting Services

Four complementary services covering every phase of the product compliance lifecycle — from first prototype through post-failure recovery:

01
NVLAP Lab Equipment · Engineer Present · Same-Day

Pre-Compliance EMC Testing

Engineering-use EMC evaluation using our actual NVLAP accredited CISPR chambers, calibrated LISNs, and IEC 61000-4 series test instruments — radiated and conducted emissions pre-scans, immunity pre-assessments, near-field source identification, and in-session fix verification. The most accurate pre-compliance data available, directly comparable to formal compliance results.

  • Radiated emissions pre-scan in CISPR semi-anechoic chamber — 30 MHz to 6 GHz
  • Conducted emissions pre-scan: 150 kHz–30 MHz via calibrated LISN
  • Full IEC 61000-4 series immunity pre-assessments — ESD, RF, EFT/Burst, surge, conducted RF
  • Near-field H/E-field probing for emission source identification
  • FCC Part 15B, EN 55032, IEC 60601-1-2, IEC 61326-1 — any standard in our scope
  • Iterative fix evaluation during the session — same-day results

02
Written Report · Prioritized Findings · Standards-Referenced

EMC Design Review

Expert evaluation of schematics, PCB layouts, and enclosure designs — performed before hardware fabrication to identify EMC issues at the lowest possible cost. Each finding is prioritized by severity, referenced to the applicable standard clause, and accompanied by a specific mitigation recommendation. Grounded in direct observation of what causes real products to fail in our accredited test chambers.

  • Schematic-level analysis: switching PSU topology, clock architecture, PDN, filters, ESD protection
  • PCB layout analysis: stackup, ground planes, decoupling placement, high-speed routing, chassis bonding
  • Enclosure and cable exit review: shielding effectiveness, aperture analysis, connector bonding
  • Standards applicability review: which tests apply and at what severity level
  • Written report with findings prioritized by compliance risk and cost-to-fix
  • Available before, during, or after hardware — schematic review through production units

03
Post-Failure Recovery · Root Cause Analysis · Fix Verification

EMC Troubleshooting

Structured diagnostic work for products that have failed compliance testing — identifying the root cause of failures and verifying that candidate fixes achieve the required margin before re-testing. Using near-field probing, conducted noise diagnostics, and in-chamber measurements with real-time engineer analysis, we provide the fastest path from a compliance failure to a confirmed fix.

  • Root cause analysis of radiated and conducted emissions failures
  • Near-field probing to localize dominant emission sources on the PCB
  • Current probe measurements to identify conducted noise coupling paths
  • Immunity failure analysis — identifying susceptible circuits and coupling mechanisms
  • Fix evaluation during the troubleshooting session — compare before/after in the chamber
  • Written troubleshooting report with confirmed fix and measurement evidence

04
Strategy · Standards · Regulatory Roadmap

EMC Design Consulting

Broader EMC and regulatory strategy consulting — helping manufacturers understand which standards apply to their product, what test program is required to reach target markets, and how to design for compliance from the outset. Delivered by engineers with direct experience running accredited tests to FCC, EU, and international standards across thousands of product submissions.

  • Applicable standards determination for target markets (US, EU, Canada, Australia, Japan, Korea, etc.)
  • Compliance test program planning — scope, sequence, cost and schedule estimation
  • EMC-aware design guidance at the architecture stage — before hardware is committed
  • Regulatory change impact assessment — new editions, standard transitions, market entry requirements
  • Multi-market compliance strategy — FCC, CE marking, ISED, RCM, VCCI, KC from a single test campaign
  • Available as project-based engagements or ongoing retainer support

Where Each Service Fits in Your Product Lifecycle

Each of the four services targets a specific phase of the product compliance lifecycle. They are designed to work together as a connected program — but each can also be engaged independently depending on where your project stands:

Pre-Layout
EMC Design ReviewSchematic & layout review before fabrication
Prototype
Pre-Compliance TestingChamber pre-scans, immunity pre-assessments, fix iteration
Post-Failure

ⓘ Pre-compliance and consulting services at Compatible Electronics are performed using the same CISPR semi-anechoic chambers, calibrated LISNs, and IEC 61000-4 instruments as formal compliance testing — giving you engineering data that closely predicts formal compliance outcomes. Results are for engineering use only and cannot be referenced in a Declaration of Conformity.

Why Compatible Electronics for Pre-Compliance & Consulting?

Same Engineers, Same Equipment

Pre-compliance and consulting delivered by the same engineers who run your formal accredited testing — full context on your product from day one through certification.

NVLAP Accredited Lab Infrastructure

Pre-compliance testing uses actual NVLAP accredited CISPR chambers and calibrated instruments — not desktop spectrum analyzers. Pre-scan data closely predicts formal compliance results.

Same-Day Results

Pre-compliance sessions typically deliver same-day or next-day results. Fix candidates can be evaluated during the session — reduce your development cycle significantly.

Three Southern California Locations

Lake Forest/Silverado, Brea, and Newbury Park — flexible scheduling across three fully equipped labs within the region. View our locations.

Direct Path to Formal Certification

Pre-compliance at Compatible Electronics is Phase 1 of a complete compliance program. The same EMC testing infrastructure transitions seamlessly to NVLAP accredited reports accepted by EU and global market surveillance.

40+ Years of Compliance Experience

Founded 1985 in Southern California. Our engineers have seen thousands of products through FCC, CE marking, medical device, and international compliance submissions.
