Designed for IEC / EN 61000-4-6

75 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-C75E

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-C75E 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-C75E is designed for testing products that

uses 75 Ohm coaxial cables for data communication.

It has 75 Ohm BNC connectors for both EUT and AE

power connection. The CDN-C75E 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 eective grounding.

All Com-Power CDNs are individually calibrated.

The Com-Power CDN-C75E 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.
