COUPLING / DECOUPLING NETWORK (CDN)
CDN S TYPE
CDN USB/C, USB/P
Designed for IEC/EN 61000-4-6
USB/c for test central devises
USB/p for test periferal devises
IEC/EN 61000-4-6 specifi es the design and performance of a range of coupling/decoupling
networks (CDNs). Each CDN is specifi c to the type of cable and the intended signal carried on
the cable. Teseq offers an extensive range of CDNs which fully comply with the requirements
of the standard and provide a simple and reliable method of injecting RF energy into the
equipment under test (EUT).
Specially designed to test the universal serial bus, now common on most PCs, this CDN is
fi tted with a USB plug (input and output) and can be used for up to 100 V and up to 1000 mA.
Two different types are available as shown in the table below:
Technical specifications CDN USB/c, USB/p
CDN USB/c
Frequency range: 150 kHz to 230 MHz
Power rating (EUT- and AE port)
AC max. voltage (line to ground): 100 V
DC max. voltage (line to ground): 100 V
Current max : 1 A
Test voltage: 200 V DC, 2 sec
Common mode impedance (EUT port)
150 kHz to 26 MHz: 150 Ω ±20 Ω
26 MHz to 230 MHz: 150 Ω +60 Ω / -45 Ω
Coupling path (In/Out port/EUT)
Connection: BNC 50 Ω
RF voltage: <20 V
Voltage division factor (RF input to EUT port)
150 kHz to 80 MHz: 9.5 dB ±1 dB
80 MHz to 230 MHz: 9.5 dB +3 dB / -2 dB
Transmission bandwidth (wanted signal) EUT/AE B3 dB: > 80 MHz sin. (data pair balanced)
