CDN 118
TELECOM LINE COUPLING/DECOUPLING NETWORK
Teseq’s CDN 118 coupling-decoupling network is designed for convenient surge testing of telecom-
munications equipme nt to IEC/EN 61000-4-5, which specifi es a 1.2 /50 μs or a 10/ 700 μs pul se. 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.
The compact CDN 118 is a complete set of coupling elements consisting of:
Telecom line surge testing
Complies with IEC/EN 61000-4-5
Complete set includes all
accessories
Easy to use bench top housing
The decoupling network itself
Interface cables to the surge generator
Four coupling adapters with a spark gap device
Four coupling adapters with a spark gap device and a 0.1 μF capacitor
Matching resistor net work 4 x 100 Ω
Matching resistor network 4 x 160 Ω
The user can manually select coupling modes by connecting the generator’s output to the appropriate input. All coupling methods described in the standard can be confi gured with the CDN 118.
