Tekbox TBISN-T4 Two Balanced Pairs ISN

Tekbox TBISN-T4 Two Balanced Pairs ISN

The Tekbox TBISN-T4 are two balanced telecom pairs ISN for conducted emissions test per CISPR 22 on two balanced pair telecom lines. The TBISN-T4 meets the requirements for Longitudinal Conversion Loss defined in CISPR 22 item 9.6.2.c)1) page 24 accepted by CISPR.
Per CISPR 22 (2005), ISNs are specialized coupling decoupling devices used for measuring the conducted asymmetric common mode radio interference voltages of ITE.
