1. Introduction

      EM5040E/5040A/5040B Line Impedance Stabilization Network is a kind of （50uH+5Ω）||50Ω V type  LISN. This product can provide stable impedance from 9 kHz to 30 MHz RF range for DUT and reference. At the same time, it isolated the useless signal from the electric network to measurement circuit and coupling the interference voltage of the DUT to the input connector of the measurement receiver. The product’s performance is compliant with standard requirements of CISPR16-1-2:2006 for V-networks. It suits conducted disturbance voltage measurement for single phase equipment well. The standard BNC output connector and 50Ω output impedance make the device compatible to the measurement equipment such as receiver and spectrum analyzer of any manufacturer. The artificial hand of the product can simulate the handle device to measure.

55031, DEF STAN59-41 and DO 160.

EM5040C LISN is a type of single line （5uH+1Ω）|| 50Ω LISN. This product can provide stable impedance from 100 kHz to 200MHz range for DUT and reference. At the same time, it isolated the useless signal from the electric network and measurement circuit and coupling the interference voltage of the DUT to the input connector of the measurement receiver. It is compliant with VDE0876 Part1 (onboard power-supply systems), VDE0879 Part2, CISPR16-1-2(Low-impedance power supplies), CISPR25 and EMC Directive 95/94/EG, DIN40839, IS07637, MIL-STD-462, MIL-I-6181D, MIL-E-55031, DEF STAN59-41 and DO 160.
