Line Impedance Stabilization Network

LISN is the abbreviation for Line Impedance Stabilization Network. Another common term for LISN is Artificial Mains Network (AMN). Com-Power developed various LISNs for conducted emission and susceptibility testing according to the most common EMC/EMI standards like MIL-STD 461D, DO-160, FCC, CISPR, EN, RTCA, and ISO. The circuit of our LISNs were designed and manufactured to meet the performance criteria given by these EMC and EMI standards.

Line Impedance Stabilization Network (LISN) / Artificial Mains Network (AMN)

A LISN/AMN performs the following functions:

• Provides a defined and stable impedance to the EuT (Equipment under Test)
• Isolates the EuT from the power source and thereby reducing potential effects of external influences while testing. Accurate and repeatable results will be facilitated this way.
• Provides an almost 1:1 (<0.5 dB insertion loss) 50Ω measurement port (coaxial, N-type) for connecting an Electromagnetic Interference (EMI) receiver or spectrum analyzer.

Protect EMC/EMI Test Equipment (highly recommended)

Use a Transient Limiter for impedance matching. It will reduce emissions that are out-of-band and transient protection for Electromagnetic Compatibility (EMC)/EMI test instruments such as Spectrum Analyzers. We highly recommend using Transient Limiters to protect your valuable testing equipment.
