Device functions and operating
The difference between the various models is:
-
Number of data lines (CDN 117A Cx-4-1 series with 4 lines
-
nominal voltage and current level of the signal- and data lines
-
various test voltage level of 4.8 kV and 6.6 kV
4.1.
Coupling network CDN 117A C4-4-1 and CDN 117A C6-4-1
1 Signal output to EUT
2 HV COM input (Generator)
3 Signal input (AE port)
4 Protection device
5 PE earth plug to ground

4.1.1.
Coupling Surge and Ringwave
The coupling networks of the CDN 117A seriesare suitable for tests according the following standards:
IEC 61000-4-5
Surge impulse with combination generator 1.2/50 µs / 8/20 µs
The GTD is line voltage related (90 V type) and inside the bridge located. Other line voltages may require an GTD
with adapted line voltage. For more information see 4.2.2. Coupling with 40 Ohm and Gas Discharge Tube (GDT)
IEC 61000-4-12
Ringwave
