EMC Pre-Compliance Testing & Debugging

Find the root cause. Fix it. Pass.

EMC failures occur often. They are predictable, diagnosable, and fixable, if you know where to look.

At Elexana, we don’t just tell you that your device fails.
We show you why it fails, and how to fix it efficiently.

What We Do

We provide hands-on EMC pre-compliance testing and collaborate with your design team to achieve a cost-effective solution that helps you pass compliance exams.

PCB analysis
Power electronics (DC-DC, AC-DC, inverters)
Embedded systems / IoT devices
Industrial equipment
Early-stage prototypes

Our goal is simple:

Get your product to pass FCC / CE compliance—faster, with fewer iterations, and lower cost.

Why Engineers Choose Elexana

1. Root-Cause Debugging (Not Just Testing)

Most labs stop at pass/fail reports.

We go deeper:

Identify dominant emission sources
Trace coupling paths (conducted, radiated, common-mode)
Isolate problem frequencies and harmonics
Provide actionable design fixes

You lead with solutions, not just data.

2. Fixes That Actually Work

We don’t recommend guesswork.

EMI filter design (input/output stages)
PCB layout improvements
Shielding strategies
Cable and grounding optimization
Switching noise mitigation

Everything is verified in real time during testing.

3. Mobile EMC Lab (On-Site Debugging)

EMC problems are often system-level.

We bring the lab to you:

Test in your real operating environment
Diagnose issues in the full system context
Iterate fixes immediately

This eliminates the typical:

Test → Fail → Redesign → Retest loop

4. Faster Path to Certification

Our clients typically:

Reduce certification iterations
Avoid costly redesign cycles
Achieve first-pass or near-first-pass success

We focus on getting you ready for final compliance testing with confidence.

Capabilities

We perform pre-compliance evaluation across key EMC domains:

Conducted Emissions

LISN-based measurements
150 kHz – 30 MHz
Line and DC input noise analysis

Radiated Emissions

Near-field probing for source identification
Far-field pre-scan measurements
Cable radiation and enclosure leakage analysis

Noise Diagnostics

Differential vs common-mode separation
Harmonic and switching noise analysis
Resonance identification

Typical Problems We Solve

Switching regulator noise (DC-DC / AC-DC)
Cable radiation from common-mode currents
Poor PCB return paths/grounding issues
Clock harmonics and digital noise leakage
Enclosure shielding failures
Unexpected resonances in the 10–300 MHz range

How It Works

Step 1 — Initial Evaluation

We test your device and identify dominant emissions.

Step 2 — Root Cause Analysis

We determine where the noise originates and how it couples out.

Step 3 — Engineering Fixes

We implement targeted mitigation strategies.

Step 4 — Validation

We verify improvements immediately with measurement data.

Who This Is For

Engineers preparing for FCC Part 15 / CE compliance
Startups approaching first certification
Teams stuck in fail–redesign loops
Power electronics and embedded system designers

Why Pre-Compliance Matters

Certification labs are expensive—and they don’t fix your design.

Pre-compliance ensures:

You understand your emissions before certification
You fix issues early, when changes are still affordable
You walk into the final testing prepared

Get Your Device Ready to Pass

If your product is:

Failing emissions tests
Producing unexpected noise
Or heading toward certification soon

We can help you identify the problem, fix it, and move forward with confidence.
