Overview

The CDN S4 XLR4 is part of the coupling decoupling network series for conducted common mode immunity testing according to IEC 61000-4-6. The CDN S4 XLR4 is compliant to IEC 61000-4-6 figure D.1 and is suitable for immunity testing on screened XLR lines with 4 pins. there is a M4 thread located at the AE side to ground as well as a 4 mm socket to connect the device to ground.

The CDN S4 XLR4 is intended to measure EuTs with XLR4 interface. The frequency range from 150 kHz to 230 MHz. The circuitry is shown in Fig. 4.

All CDNs comply to the requirements of IEC 61000-4-6. Each CDN comes with individually measured data and a calibration certificate for the common mode impedance and the voltage division factor. Further typical data for the phase (not normative) can be found in fig. 2

A variety of calibration adapters and other accessories are available as option. With the two included adapters SA XLR in conjunction with the optional series resistor SR100-6W, the required spacing of 30 mm is obtained as depicted in Fig. 9 of IEC 61000-4-6. The adapter comes with an indexing slot and can only be mounted with its screw facing upwards.

The connection to ground can be accomplished using the ground plane of the CDN. Additionally there is a M4 thread located at the AE side to ground as well as a 4 mm socket to connect the device to ground. The CDN is equipped with 4 mounting notches of 6 mm width at the baseplate.
