Unshielded Unsymmetrical Data Lines
Unshielded unsymmetrical data lines are generally used for analog communication signals and low frequency digital signals. Such data lines are tested according to IEC 61000-4-5 Ed.3 Figure 9 on both line-to-line and line-to-ground coupling paths.
There are 3 solutions available from EMC Partner for such data lines: CDN-KIT1000 ED3 (max. 2 lines), CDN-DATA-4L (max. 4 lines) and CDN-DATA-8L (max. 8 lines).
CDN-DATA-4L and CDN-DATA-8L are easy to use and versatile coupling decoupling networks for unsymmetrical unshielded lines. These CDN are used to induce up to 6kV Combination Wave Surge (IEC 61000-4-5) and 6kV Ring Wave (IEC 61000-4-12) disturbances on devices with up to 8 data lines (4 pair). Both CDN-DATA-4L and CDN-DATA-8L can be used with the IMU Series of transient generators to meet test requirements per IEC 61000-4-5 Ed.3 Figure 9.

Unshielded Symmetrical Data Lines
Unshielded symmetrical data lines are generally used for high speed communication signals (Ethernet lines up to 1Gbps, USB, CAN bus, RS-485 etc.). Such data lines are tested according to IEC 61000-4-5 Ed.3 Figure 10 or Figure 11 coupling all lines to PE.
There are 2 solutions available from EMC Partner for high speed lines: CDN-UTP ED3 (max. 4 lines) and CDN-UTP8 ED3 (max. 8 lines). These CDNs are used to induce up to 6kV Combination Wave Surge (IEC 61000-4-5), 6kV Telecom wave surge (10/700us) and 6kV Ring Wave (IEC 61000-4-12) disturbances on devices with up to 8 data lines (4 pair). In addition to this, up to 4 unsymmetrical lines can be tested making the CDN-UTP8 ED3 incredibly versatile. The CDNs are designed for high speed Ethernet testing applications up to 1 gigabit speeds. RJ45 adapter boxes are provided for convenient connection between the device under test and auxiliary equipment to the CDN. Both CDN-UTP ED3 and CDN-UTP8 ED3 can be used with the IMU Series of transient generators to meet test requirements per IEC 61000-4-5 Ed.3 Figure 10 and 11.
Shielded Symmetrical and Unsymmetrical Data Lines
Shielded symmetrical and unsymmetrical data lines do not require a CDN for testing. These data line are tested according to IEC 61000-4-5 Ed.3 Figure 12. Both IMU-MGS or IMU-MGE generators can be used to apply the Combination Wave Surge (IEC 61000-4-5) disturbances directly on to the shield, as shown below:
