Wide frequency coverage
EMC testing spans from low-frequency conducted emissions to high-frequency radiated fields, requiring probes with broad bandwidth and flat frequency response.
EMC Testing
Wide-bandwidth current and voltage probes for conducted and radiated EMC pre-compliance, troubleshooting, and certification preparation across power electronics and automotive systems.
Testing Challenges
Probe-induced field disturbance
Inserting measurement probes into a test setup can alter the EMI profile. Minimizing loop area and probe loading is critical for meaningful results.
Distinguishing noise from signal
In dense power electronic systems, separating measurement artifacts from real emissions requires careful probing technique and high CMRR.
Practical measurement support for EMC testing
EMC pre-compliance and troubleshooting demand probes and sensors that can operate reliably across wide frequency ranges with minimal disturbance to the measurement environment.
Accuracy first
Measurement tools must remain dependable under demanding development and validation conditions.
Built for real test benches
The measurement chain is designed for practical lab, production, and troubleshooting environments.
Long-term technical support
Selection guidance, usage support, and maintenance services help reduce lifecycle friction.
Typical Test Scenarios
Conducted emissions pre-compliance
Measure common-mode and differential-mode conducted noise on power lines using high-bandwidth current and voltage probes.
Radiated field pre-scan and diagnosis
Use near-field probes and wideband sensors to locate emission sources and evaluate shielding effectiveness.
EMI root-cause analysis
Trace noise propagation paths in power converters, motor drives, and switching circuits to identify emission origins.
