cdn 117
data line coupling/decoupling network
Teseq’s CDN 117 coupling-decoupling network enables convenient testing with surge pulses of
1.2/50 μs on data, signal or peripheral lines, as specied in many product standards. The test method,
severity levels, permissible reaction of the EUT and specication of the coupling networks are included
in IEC/EN 61000 -4-5.
The compact CDN 117 is a complete set of coupling elements consisting of:
The decoupling network itself
Interface cables to the surge generator
Data line surge testing
Easy to use bench top housing
Conforms to IEC/EN 61000-4-5
Complete set includes all
accessories
A coupling adapter with a 0.5 μF capacitor
A coupling adapter with a spark gap device
A coupling adapter with a 0.1 μF capacitor in parallel with a spark gap device
All coupling methods described in IEC/EN 61000-4-5 for unshielded unsymmetrical line pairs can
be performed both in differential- and common mode coupling (line-to line and line-to-ground).
The user can manually select coupling modes by connecting the surge generator’s output to the
appropriate input of the CDN 117.
Several CDN 117s can be arranged in parallel for applications in which more than two conductors
must be decoupled.
The CDN 117 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.
