This part of IEC 61000 pertains to emission and immunity test methods for electrical and
electronic equipment using various types of transverse electromagnetic (TEM) waveguides.
These types include open structures (for example striplines and electromagnetic pulse
simulators) and closed structures (for example TEM cells). These structures can be further
classified as one-port, two-port, or multi-port TEM waveguides. The frequency range depends
on the specific testing requirements and the specific TEM waveguide type.
The object of this standard is to describe
TEM waveguide characteristics, including typical frequency ranges and equipment-under283
test (EUT) size limitations;
TEM waveguide validation methods for electromagnetic compatibility (EMC) tests;
the EUT (i.e. EUT cabinet and cabling) definition;
test set-ups, procedures, and requirements for radiated emission measurements in TEM
waveguides; and
test set-ups, procedures, and requirements for radiated immunity testing in TEM
waveguides.
NOTE Test methods are defined in this standard for measuring the effects of electromagnetic radiation on
equipment and the electromagnetic emissions from equipment concerned. The simulation and measurement of
electromagnetic radiation is not adequately exact for quantitative determination of effects for all end-use
installations. The test methods defined are structured for a primary objective of establishing adequate
reproducibility of results at various test facilities for qualitative analysis of effects.
This standard does not intend to specify the tests to be applied to any particular apparatus or
system(s). The main intention of this standard is to provide a general basic reference for all
interested product committees of the IEC. For radiated emission measurements, product
committees should select emission limits and measurement methods in consultation with
CISPR standards. For radiated immunity testing, product committees remain responsible for
the appropriate choice of immunity tests and immunity test limits to be applied to equipment
within their scope. This standard describes test methods that are separate from those of
