 The LI-3P-1x series consists of four four-conductor, 50Ω / 50 μH Line Impedance Stabilization Networks (LISNs) with different ratings. These LISNs can be operated remotely or locally, with remote switching using the RLI-100 Remote LISN Interface or selecting the line using a mechanical four-position switch. The selected line is terminated by the measuring instrument's 50-ohm impedance.  

 The LI-3P-2X series consists of four four-conductor, 50Ω / 50 μH Line Impedance Stabilization Networks (LISNs) with a frequency range of 9 kHz to 30 MHz. These LISNs have different current ratings and can be operated remotely or locally. The side panels are louvered for cooling purposes, and the LI-3P-263 and LI-3P-2100 have internal cooling fans. Lines not selected are internally terminated into 50 ohms.  

 The LI-3P-4x Series comprises four four-conductor Line Impedance Stabilization Networks (LISNs) with varying current ratings. These LISNs are used for power line conducted emissions compliance testing, providing a stable power line impedance, isolating the Equipment Under Test (EUT), and coupling disturbance voltages to the coaxial measurement port. They use air-core inductors, unpainted mounting plates, louvered side panels, and internal cooling fans.
