LISN Types
Under a particular EMC test standard, a specific LISN type is required for evaluating and characterizing the operation of the EUT.
Different types of LISNs are available for analyzing dc, single-phase or 3-phase ac power connections. The main parameters for selecting the proper type of LISN are impedance, insertion loss, voltage rating, current rating, number of power conductors and connector types. The upper frequency limit of the LISN also plays an important role when conducted emissions measurements are used for predicting radiated emissions problems. A 100MHz LISN is used in those cases.

Famous quotes containing the word types:
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
