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

• 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.
