Test Setup with CDN’s
The following information is important for a correct test setup as per. IEC:
Fig 6.10 :Test setup with CDN
1. All lines not being tested must be decoupled:
-
with CDN’s where the RF input ports are terminated by a 50
load resistor
- with an EM Clamp
- with ferrites components on the cables
2.
The CDN’s must be connected securely to the ground reference plane.
3. The lines of the EUT must be separated by 30mm (1.2 inches) from the ground reference plane (whenever
possible). This also applies for lines not being tested.
4. The EUT must be separated by 100mm (4 inches) from the ground reference plane.
5. The coaxial cables must be as short as possible. It is recommended to use the cables provided by CWS
500N2.
6. The 50
matching resistor must be an adequate RF type.
