Atec LISN-50, LISN-100 User Manual
A wide range of EMC test specifications including CISPR 22, FCC, ANSI C63.4 and many
others use a standard 50, 50uH and its primary variant the 50, 50uH +5 for conducted
emissions testing. CISPR 16-1-2 most precisely defines the performance requirements of
these devices.

For connector options, please see table 3, (xx) defines EUT power connections, (x) defines
number of lines All the models listed above meet the performance requirements for
the 50, 50uH LISN circuit defined in CISPR 16-1-2, 2006, including the common mode
impedance, phase and decoupling isolation.
An alternative LISN circuit, 50, 50uH +5, 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 of luminaries. It includes additional
inductors and capacitors for filtering and has an operating frequency of 9kHz – 30MHz.
