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.
The Model 3925/2 is a two line single phase PLISN for TEMPEST testing. It is divided into a low frequency section of 5kHz to 20MHz and a high frequency section of 2MHz to 1 GHz. The low frequency section is rated at 15 amps with a line voltage drop of 10%. The high frequency section is rated at 20 amps with a maximum drop of 2.5%. Iron core coils are used in this PLISN to provide the proper impedance at lower frequencies. Type N female connectors are used for power output to the EUT. An AC adapter is also provided. Type BNC connectors are used for monitoring the output.
