Line impedance stabilisation networks

LISNs are key components in EMC testing. To monitor undesirable emissions on the supply line, the LISN is inserted into the device under test’s supply line and utilised in conjunction with a measurement receiver or spectrum analyzer. Typically, the receiver or spectrum analyzer is operated by software such as EMCview. The software guarantees that the analyzer’s settings are in accordance with CISPR 16 specifications and allows you to load and run pre-configured tests for all main EMC standards. The measurement data points are graphed along with the selected standard’s limits and can be exported as test report.
One of the most important characteristics of a LISN is that it provides a fixed source impedance for the device under test. This assures that the measurement is repeatable, regardless of the output impedance of the power source used. This attribute is also used in many other EMC test setups that use LISNs to establish a fixed supply impedance rather than measuring transmitted emissions. As a result, LISNs can be found in test setups for radiated emissions, immunity testing, and a variety of other applications.
