WebPerforming precompliance measurements on power supplies requires using a line impedance stabilization network (LISN) for results that can be compared to limit values. While LISNs are standard in any … WebApr 2, 2024 · More specifically, the LISN is a passive network that provides a definite and constant termination impedance (close to 50 Ω) across the EUT power terminals over the applicable test frequency range dictated by each standard. It is also useful to isolate the EUT from ambient noise on the respective AC or DC power lines over the test frequency … WebWe offer LISN (Line Impedance Stabilization Network) manufactured by Schwarzbeck Mess-Elektronik and COM-Power Corporation. The LISN are fully comliant to the current major national and international standards such CISPR16, CISPR22 and CISPR25. The LISNs are used to measure disturbance voltages from equipment under test's AC power terminal. diaper rash spray recipe
