Coupling Decoupling Networks

   Laplace Logo 

LAPLACE INSTRUMENTS LIMITED

Designed specifically to meet the conducted RF immunity testing conditions specified in EN61000-4-6

The Coupling/Decoupling Network (CDN) facilitates the testing of EMC immunity by coupling RF directly to or from cables connected to the equipment under test. This technique is the preferred method for immunity testing according to IEC61000-4-6. CDNs can also be used for pre-compliant emissions measurements according to EN55022.

Laplace Enhanced Coupling Decoupling Network (CDN)

New Enhanced CDN

 

Data

Just 5 models to cover over 25 different cable types

User configurable

Fully compliant (IEC61000-4-6)

Enhanced models feature feedback output.

  • Calibrated to the RF level applied to the cable.
  • Includes detector to provide DC level.
  • Removes uncertainty due to unknown EUT cable impedance.
  • Ensures accurate control of stress level.
  • Eliminates requirement for the 6dB attenuator in the RF feed.

Fully calibrated.

All include matching cables and adaptors.
Reduce equipment costs and maximise flexibility due to the Versatile benefits of the range.
Just 5 models cover over 23 different cable types.

OPTIONS
46ZZImpedance adaptor pair
For on-site calibration of x46xx VCDN and 22L test adaptor.
Connects directly to the CDN EUT and AE ports.
Fitted with BNC or N type RF sockets (specify with order).
Whilst conforming to the requirements of IEC61000-4-6, the 46ZZ has
built-in spacing to establish the 30mm separation from the CDN.		 46GPGround plane
An Aluminium ground plane with
sprung retainers to hold 1 or 2 CDNs
during calibration and use. Compact,
convenient & transportable.
An extension plate (46XP) is available
to cope with larger EUTs.		 22L Emission receiver adaptor
For emission testing of telecom ports with the Enhanced model, the 22L
adaptor secures the appropriate impedance matching according to
EN55022:1998 Fig D4.

The Laplace 46 series of CDNs is unique in offering 2 distinct and unique features:

Versatility™. The 46 series are programmable such that many different cable types can be accommodated with one CDN.
Enhanced™. The "E" version provides a calibrated feedback signal so that the stress level can be accurately controlled during the test.

Each model is shipped complete with an appropriate set of adaptors and cables.

Calibration adaptors and modular ground plane sets also available.
