EMCO Line Impedance Stabilization Networks (LISNs) and Power Line Impedance Stabilization Networks (PLISNs) are multi-line low pass filter networks used for conducted emissions measurement. LISNs and PLISNs 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, EMCO's Model 3701 Line Probe can be used for EMI volage measurements.
