3725-2M LISN
​ETS-Lindgren's Model 3725/2M Line Impedance Stabilization Networks (LISNs) are multi-line low pass filter networks used for conducted emissions measurement.



​ETS-Lindgren's Model ​3725/2M 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 Ω RF connection to measure EMI voltage generated by the EUT. When line currents drawn by the EUT are too great for a LISN, the model 3701 can be used for EMI voltage measurements.
