ISN 2 Pair Balanced Type TBISN-T4
According to CISPR 22 (2005), the ISN is a special coupling and decoupling device used to measure the conducted asymmetric common mode radio interference voltage of ITE. The TBISN-T4 is designed to conduct conducted emission tests in accordance with CISPR 22 for balanced communication lines with 2 pairs. It meets the requirements for longitudinal conversion loss specified in item 9.6.2.c)1) (page 24) of CISPR 22 and is approved by CISPR.
