8.1. 

Test Setup with CDN’s  

The following information is important for a correct test setup: 

 

 

Fig 8.1 :Test setup with CDN 

 

•

 

Each, the EUT and the AE are 

10 cm isolated

 above the reference ground surface. 

•

 

All outgoing lines have to be 

decoupled via CDN

. 

•

 

The CDNs have to be inserted in a distance of 

0.1 m up to 0.3 m 

from the EUT. 

•

 

The CDNs have to be connected well 

with

 the 

reference ground plane 

in a RF-accordant manner. 

•

 

Only 

one

 CDN is terminated with 

a 50

 load resistor.

 

•

 

Refer to IEC 61000-4-6 Standard for more information to terminate coupling/decoupling devices
