Conducted Emissions Testing Services
Conducted emissions testing measures the electromagnetic noise that travels back through power lines and signal cables from your electronic device. Compatible Electronics provides comprehensive conducted emissions testing to FCC, CISPR, and international standards.
What is Conducted Emissions Testing?
Conducted emissions are electrical disturbances generated by electronic equipment that propagate through power lines, signal cables, and interconnections. These emissions can affect other devices sharing the same electrical infrastructure, making compliance testing essential.
