Impedance Stabilization Networks (ISN's)

(Showing 2 of 26)

Impedance stabilization networks (ISN's) are similar to LISN's but used for conducted emissions measurements on signal and data lines. They differ from LISN's in that they can perform Comon-Mode impedance measurements. CISPR 22 and CISPR 32 are common standards requiring the use of an ISN.

ISN's are referred to as an asymmetric artificial network (AAN) in CISPR 16-1-2.
