Datasheet Other1
The ISN T8 is designed for measurements on up to four unshielded single balanced pairs shown at D.3 (ISN with high longitudinal conversion loss (LCL) for use with one, two, three, or four unscreened balanced pairs) in CISPR 22, Ed.5.2, 2006 and EN 55022 Sept. 2006 (IEC/CISPR 22: 2005 modified). The ISN T8 consists of one basic network (ISN T800) with D-Sub-25- connectors and special adapter sets. A set of adapters consists of two pieces of LCL adapters to arrange the lines and realize longitudinal conversion loss (LCL)- requirements for the EUT-side in relation to the use cable category (cat.3, cat.5) and one piece of connection adapter arranges the lines for the AE-side.
