Designed for IEC / EN 61000-4-6
50 Ohm Coaxial Cables
Individual calibration included
Three Year Warranty
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-C50E
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 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-C50E is a part of the series of
Coupling/Decoupling Networks designed specifically
for testing product for conducted immunity per
IEC/EN 61000-4-6.
The CDN-C50E is designed for testing products that
uses 50 Ohm coaxial cables for data communication.
It has 50 Ohm BNC connectors for both EUT and AE
power connection. The CDN-C50E can handle up to
1 Amp 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 effective grounding.
All Com-Power CDNs are individually calibrated.
The Com-Power CDN-C50E 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 amplifier and all accessories
required for the test.
