27、adiated 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. A test method comparison table is included as annex A to assist in selecting the appropri
28、ate measurement method(s). The object of this standard is to describe general conditions in order to establish a uniform 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 des
29、cribed. Deviations from this standard are noted explicitly in the individual test report. The measure- ment 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 cont
30、rolled conditions, yields information about the potential for RF disturbances in an application of the integrated circuit. 2 Normative references The following referenced documents are indispensable for the application of this document.
