IEC 61967-1:2018 pdf download.Integrated circuits – Measurement of electromagnetic emissions – Part 1: General conditions and definitions
1 Scope
This part of IEC 61 967 provides general information and definitions on the measurement of conducted and radiated electromagnetic disturbances from integrated circuits. It also provides a description of measurement conditions, test equipment and set-up as well as the test procedures and content of the test reports. Test method comparison tables are included in Annex A to assist in selecting the appropriate measurement method(s). The object of this document is to describe general conditions in order to establish a uniform testing environment and to obtain a quantitative measure of RF disturbances from integrated circuits (IC). Critical parameters that are expected to influence the test results are described. Deviations from this document are noted explicitly in the individual test report. The measurement results can be used for comparison or other purposes. Measurement of the voltage and current of conducted RF emissions or radiated RF disturbances, coming from an integrated circuit under controlled conditions, yields information about the potential for RF disturbances in an application of the integrated circuit. The applicable frequency range is described in each part of IEC 61 967.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 artificial network AN network presenting a reference load impedance (simulated) to the DUT (e.g. extended power or communication lines) across which the RF disturbance voltage is measured and which isolates the apparatus from the power supply or loads in a given frequency range Note 1 to entry: This note applies to the French language only. 3.2 associated equipment transducers (e.g. probes, networks and antennae) connected to a measuring receiver or test generator, also transducers used in the signal or disturbance transmission path between a DUT and measuring equipment or a (test-) signal generator 3.3 broadband disturbance broadband emission electromagnetic disturbance which has a bandwidth greater than that of a particular measuring apparatus, receiver or susceptible device Note 1 to entry: For some purposes, particular spectral components of a broadband disturbance may be considered as narrowband disturbances. Note 2 to entry: Emission that has a bandwidth greater than that of a particular measuring apparatus or receiver.
