NSG 3040 EMC test system
14.6.3 Surge pulse CDN for symmetric datalines CDN 118
Teseq’s CDN 118 coupling-decoupling network
is designed for convenient
surge testing of telecommunications equipment to IEC/EN 61000-4-5, which
specifies a 1.2/50 or a 10/700 μs pulse.
The CDN 118 includes the special decoupling network and coupling elements
that are required for these tests.
The CDN 118 can be easily interfaced with the EUT
and is designed as a
bench top unit. It can be used with Teseq’s NSG series or any industry standard
surge generator with the appropriate connector adapter.
