ETS-Lindgren Line Impedance Stabilization Networks (LISNs) are multi-line low pass filter networks used for conducted emissions measurement. LISNs isolate an electrically powered EUT from the external power source, stabilize line impedance (for repeatable measurements), and provide a 50-ohm RF connection to measure EMI voltage generated by the EUT. When line currents drawn by the EUT are too great for a LISN, Model 3701 Line Probe can be used for EMI voltage measurements.
