A wide range of EMC test specifications including CISPR 22, FCC, ANSI C63.4 and many others use a standard 50 Ω, 5 µH and its primary variant the 50 Ω, 5 µH +5 Ω for conducted emissions testing. CISPR 16-1-2 most precisely defines the performance requirements of these devices. An alternative LISN circuit, 50 Ω, 5 µH +5 Ω is often used by test engineers to perform conducted emission testing defined in CISPR test specifications. This LISN originated with VDE conducted emissions testing. It is also the LISN required for CISPR 15 testing luminaries.
