it does not pose an immediate problem. However
it is an issue with normalized site attenunation measurements. More work is
currently being done in this area and the issues are being addressed.

for performance measurements of absorbers
that I'm aware of. The de facto absorber test standard referenced by most
absorber manufacturers is a university of Michigan report describing the
arch method (plane wave).
Hope this helps.

, you will even out
the variations which will result in fairly usable, repeatable numbers. The
size of the room determines the usable frequency range.

This message is coming from the emc-pstc
application,
but they do go into mechanical and durability issues.
Just thought I'd mention it.

This message
SAE and CISPR standards, but I'm wondering which
ones are mandated by the EU. Any directives on that?
I would also like to hear from test houses who can do the kind of testing
(EMC and safety) as described in the standards on vehicle testing.
Happy holidays to all.

customers decide on the best solution for the customer's testing
requirements. Independent consultants do not gain from selling anything.
There is a difference. Just an FYI.

designs are close to the practical limits on footprint (dictated by
measurement range and quiet zone size) and performance.

if the tester is not aware of
the problem.
For better repeatability and better NSA measurements, ferrites are
required. They do not make the cable totally RF-invisible but do
considerably reduce the influence of the cable on the measurements.
