LAPLACE CDNS - COUPLING-DECOUPLING NETWORK
Laplace supply a wide range of CDNs that are fully compliant to IEC61000-4-6.
In addition to a range of ‘conventional’ CDNs, Laplace are unique in offering two other types. Both types are ‘versatile’ in that they are configurable, offering great flexibility in terms of the type of cable each model can be used with. This reduces the number of CDNs necessary to hold in stock. The final type is, in addition to being versatile, fitted with an output which monitors the RF level applied to the cable.
Type |
Description |
Standard |
Conventional CDNs. Compliant to IEC61000-4-6. |
Versatile |
Compliant to IEC61000-4-6. Just 5 models. Each model is versatile and can be configured to suit a wide range of cable types. Over 25 different cable types can be accommodated by these 5 models. |
Enhanced |
Identical to the versatile type described above, but with the additional benefit of the inclusion of a feedback network and detector such that the applied stress level can be monitored and used (if required) as part of the level control system. |
Standard
These are grouped into three classes:
• Mains power cables
• Unscreened cables
• Screened cables
Versatile and Enhanced
These types are multi-functional. This versatility means that the need to carry a large range of different types of CDN to cope with potential requirements is avoided. One type of calibration adaptors fits all models. Each type includes just 6 basic models:

In addition, the S46M5/9 is a multi-function CDN capable of 100A rating for M3 and M2 configuration, or 50A in M5 and M4 (three phase) configurations. This CDN also has an additional 4 cores rated at 6A for ground wire, control or sensing requirements.
Each model can be configured to cover a wide variety of cables, and still maintain full compliance with IEC61000-4-6. The Enhanced models can be used in conjunction with a suitable signal generator such that closed loop level control can be achieved. This offers the advantages of greater efficiency, reduced RF power requirement and better accuracy for the applied RF level.
Note that the RFIC-4-6 synthesiser system from Laplace offers the capability to work with the enhanced CDNs (as well as standard and versatile types). Other synthesisers will not work in the ‘enhanced’ mode.
