ISN T2 Series
Impedance stabilization networks (ISN, or with CISPR 16-1-2 called AAN: asymmetric artificial network) are defined for measuring of conducted common mode disturbances at information technology equipment (ITE) as required in CISPR 22 and CISPR 32. The ISN is placed between the equipment under test (EUT) and auxiliary equipment (AE) or load which are necessary for the operation of the EUT. The ISN establishes the common-mode termination impedance for the EUT’s telecommunications port during measurement and emulates the unsymmetrical contribution (longitudinal conversion loss, LCL) of the connected line. Different ISNs are available in relation to the line category, line numbers and pin-arrangement. The ISN T2A is designed for measurements on one unscreened balanced pair and consists of one basic network (ISN T200A) with D sub 25 connectors and special adapter sets. A set of adapters consists of LCL adapters to realize the longitudinal conversion loss (LCL)- requirements for the EUT-side in relation to the used cable category (cat. 3, cat. 5) and a connection adapter for the AE-side.

CAS ISN
The calibration kit CAS ISN is made for function tests and remeasurements on impedance stabilization network (ISN) for unshielded balanced pairs. Measuring parameters are common mode (CM) impedance, phase angle, voltage division factor, decoupling attenuation (isolation) and longitudinal conversion loss (LCL). Impedance stabilization networks (ISN) are defined in CISPR 22 and CISPR 16-1-2. The CISPR 16-1-2 gives additional requirements and provides examples and measurements for the networks. The ITU-T recommendations G.117 and O.9 offers the background knowledge for measurements on symmetrical telecommunication lines.
