Teseq CAS ISN Extension for Cat. 6

The extension kit for the CAS ISN is made to perform transmission and crosstalk measurements on
impedance stabilization network (ISN) for unshielded balanced pairs. In combination with the CAS ISN
and its extensions for T2 and cable category 6 all necessary adapter have been included to measure
common mode (CM) impedance, phase angle, voltage division factor, decoupling attenuation (isolation),
longitudinal conversion loss (LCL), transmission and crosstalk measurements.
