Precision Meets Innovation: Introducing SIQ’s Common Mode Absorbing Device (CMAD)

Every EMC engineer knows how challenging it can be to achieve reproducible radiated emission results — especially when common-mode currents on cables interfere with your setup.
That’s why our R&D and EMC testing experts at SIQ Ljubljana developed the Common Mode Absorbing Device (CMAD) — an advanced tool designed to stabilize and standardize test environments for more consistent and reliable results.
Designed for EMC and compliance professionals:
- Ensures defined common-mode impedance on cables exiting the test area (semi-anechoic chamber, GTEM cell, etc.)
- Reduces measurement uncertainty and test-to-test variability
- Fully compliant with CISPR 16-1-4, CISPR 16-2-3, CISPR 11 / EN 55011, EN / IEC 61000-6-3, EN / IEC 61000-6-4, and EN / IEC 60601-1-2 (Ed. 4.1)
- Available for purchase and calibration, so your lab can apply the same precision standard used at SIQ
What are the benefits:
With CMAD, EMC professionals can focus on what truly matters — the integrity of their measurements. By controlling the often-overlooked cable effects, you get more reproducible results, better correlation between labs, and faster product qualification.
