Abstract: Radiated Electromagnetic Compatibility (EMC) tests
usually apply a positioning table in the test zone of the EMC facility.
The Equipment Under Test (EUT) is positioned on this table as
prescribed by EMC standards. The EMC standards implicitly assume
that the influence of the table is negligible as long as such a table
complies with the qualitative specification in the standard. In view of
the work associated with the uncertainties of EMC standards, the
influence of positioning tables is investigated for both radiated
emission and immunity testing. Measurement results and simple
simulations demonstrate that the impact of a ‘non-conductive table’
may be significant. Requirements for positi ..
