TEKBOX TBISN-T4 Two Balanced Pairs ISN
Per CISPR 22 (2005), ISNs are specialised coupling decoupling devices used for measuring the conducted asymmetric common mode radio interference voltages of ITE. TBISN-T4 has been designed to perform conducted emissions testing per CISPR 22 on two balanced pair telecom lines. It meets the requirements for Longitudinal Conversion Loss, as defined in CISPR 22, item 9.6.2.c)1) page 24 accepted by CISPR.
