LISN ( Artifical Mains Network) is a low-pass filter typically placed between an AC or DC power source and the EUT (Equipment Under Test) to create a known impedance as per complying standard for the measurement of conducted emission. It also isolates the unwanted RF signals from the power source with pre-filter included. It provides a Radio frequency (RF) noise measurement port.
LISN is used to predict conducted emission for diagnostic, pre-compliance and compliance testing.
Scientific designs and manufactures models in compliance with CISPR 16-1-2 : 2014, EN, ANSI C63.4, FCC, ETS, VCCI and VDE, MIL461E/F standards and automotive for measurements in commonly used Standards.
These LISNs are Single Phase, 2 Wire networks.Appropriate line can be selected by a rotary switch. The other line will be terminated internally with 50Ω.
Artificial Hand simulation 510Ω + 220pF impedance in accordance with CISPR 16-1-2: 2014 is provided. Standard Input and Output terminals provided are Indian / CEE Sockets, however optional wing terminal and SUPERCON connectors can be ordered.
A transient limiter is highly recommended to use with LISN at the front end of EMI Rx or Spectrum Analyzer to protect measuring instrument from transients.Features:
- Rotary switch for Line and Neutral
- Available with BNC Connector / N type (F) connector option
- EUT connector: Indian / CEE/ Schuko / SUPERCON / Wing Terminal options available
- Transient Limiter
- Common mode/ Differential mode option
- Remote Control
