Overview
The Emco 3825-2 LISN is a multi-line low pass filter network used for conducted emissions measurement.LISNs and PLISNs isolate an electrically powered EUT from the external power source, stabilize line impedance, 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, the EMCO 3825-2 probe can be used for EMI voltage measurements.
