Test Setup for I/O and datalines

Arrangement:
The CDN 118A series is placed on the top or on the side
of the surge generator.
Connections frontside
Couplings: All couplings for surge pulses are realized
with short circuit connectors.
Data lines: L1...L4 Output to EUT
Connections rear side:
1 Earth: Earth bolt generator - CDN 118A-Cx-4-1
and additional layer to the system GND
A low inductice copper band or the delivered
cable from the earth set (green-yellow cable).
2 Twisted high voltage cable from generator to CDN
HV-cable : HV generator - HV CDN 118A
red
HV-cable : COM generator - COM CDN 118A
black
HV-COM plug on CDN 118A device
3 HV and COM generator output CDN 118A-Cx-4-1
4 AE Port protection
5 AE Port Input, Transducer - Sensor
Example of a test setup with an NSG 3040A or NSG 3060A generator and CDN 118A-Cx-4-1 coupling / decoupling
network. It is important to connect GND wire from CDN 118A-Cx-4-1 to the impulse generator. The HV impulse
cables between the generator and CDN 118A-Cx-4-1 must be twisted for mimimize the magnetic field influence.
The device earth bolt must be connected to the ground reference plane if there is one. In other case
user is responsible that the generator earth bolt is proper connected with the building earth.
Earth set
The earth set is part of the delivery and includes a
length of 0.6m
