29、IC EMISSIONS, 150 kHz to 1 GHz Part 1: General conditions and definitions 1 Scope This part of IEC 61967 provides general information and definitions on measurement of conducted and radiated electromagnetic disturbances from integrated circuits. It also provides a description of measurement conditio
30、ns, test equipment and set-up as well as the test procedures and content of the test reports. A test method comparison table is included as annex A to assist in selecting the appropriate measurement method(s). The object of this standard is to describe general conditions in order to establish a unif
31、orm testing environment and 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 standard are noted explicitly in the individual test report. The measure- ment results c
32、an 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 cir
