Teseq improves the handling of the ISN recalibration, now possible with CAS ISN,
and offers a wider application range with changed ISN family to new ISN T2A and ISN
T4A. Both ISNs are for emission measurements of CISPR 22 (EN 55022) and immunity testing of IEC 61000-4-6 (EN 61000-4-6) as well. The redesigned networks allow an
increased EUT current.
