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 EnhancedCoupling Decoupling Network (CDN)
Just 5 models to cover over 25 different cable types
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
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.

46ZZ Impedance adaptor pair
For on-site calibration of x46xx VCDN and
22L test adaptor.
Connects directly to the CDN EUT and AE
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.
46GP Ground 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.
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
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.
