Impedance Stabilization Networks (ISN's)

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.

Impedance Stabilization Networks (ISN's) There are 31 products.
