BS EN IEC 61000-4-20:2022 PDF

Scope: 1 Scope This part of IEC 61000 focuses on 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 document is to describe — TEM waveguide characteristics, including typical frequency ranges and equipment-under-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 . ...
