Application
During conducted Immunity testing, CDNs are
utilized to provide a means of coupling RF common
mode signals to each line. In addition, CDNs provide
the required common mode impedance to the EUT,
isolation to the auxiliary equipment via common
mode decoupling of the disturbance signals and
provide uninterrupted communication between
the EUT and auxiliary equipment.
Before you begin testing with the CDN-T8SE
you will need to establish calibrated drive levels
corresponding to your desired test levels. During
drive level calibration, the RF signal level being
injected to the CDN is adjusted incrementally until the
voltage level measured at the 150Ω to 50Ω adapter
(ADA-515-2) connected to the EUT port of the CDN
is approximately equal to the Umr value given in the
table below. The ADA-515-2 and accessories needed
for this test are available from Com-Power.

Description
Com-Power CDN-T8SE is a part of the series of
Coupling/Decoupling Networks designed specically
for testing product for conducted immunity per
IEC/EN 61000-4-6.
The CDN-T8SE is designed for testing products
that uses four screened, balanced pairs for
communication such as Ethernet. It has a shielded
RJ45 connector for both EUT and AE connections.
The CDN-T8SE can handle up to 2 Amps of current.
The RF disturbance signal coupling port is female
BNC. It can handle up to 40V of RF Input Voltage.
The bottom surface of the CDN is not painted for
easy and eective grounding.
All Com-Power CDNs are individually calibrated.
The Com-Power CDN-T8SE fully complies with the
requirements contained in the IEC 61000-4-6 and
CISPR 16-1-2.
All Com-Power CDNs can be purchased separately
or as part of the CIS series conducted immunity test
system. This is a pre-packaged solution that includes
an ACS series power amplier and all accessories
required for the test.
