ISN T8-Cat6

Impedance Stabilization Network (ISN) for Unscreened Balanced Pairs

ISN T8-Cat6zoom
  • For use with one, two, three, or four unscreened balanced pairs
  • Refers schematic circuit example in CISPR 22/32 Figure D.3/G.3
  • Intended for connection to cable category 6
  • 1000BaseT and PoE application
  • Can be used as CDN for IEC/EN 61000-4-6 immunity tests
 

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 T8-Cat6 is designed for measurements on up to four unscreened single balanced pairs with cable category cat. 6. It can also be used as CDN for immunity testing according IEC/EN 61000-4-6 up to 80 MHz.
