CISPR 24:2010+AMD1:2015 CSVWithdrawn Consolidated version
Information technology equipment - Immunity characteristics - Limits and methods of measurement
Abstract
CISPR 24:2010+A1:2015 applies to information technology equipment (ITE) as defined in CISPR 22. The object of this publication is to establish requirements that will provide an adequate level of intrinsic immunity so that the equipment will operate as intended in its environment. The publication defines the immunity test requirements for equipment within its scope in relation to continuous and transient conducted and radiated disturbances, including electrostatic discharges (ESD). Procedures are defined for the measurement of ITE and limits are specified which are developed for ITE within the frequency range from 0 Hz to 400 GHz. For exceptional environmental conditions, special mitigation measures may be required. Owing to testing and performance assessment considerations, some tests are specified in defined frequency bands or at selected frequencies. Equipment which fulfils the requirements at these frequencies is deemed to fulfil the requirements in the entire frequency range from 0 Hz to 400 GHz for electromagnetic phenomena. The test requirements are specified for each port considered. This second edition cancels and replaces the first edition published in 1997, and its Amendments 1(2001) and 2(2002). It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - dated references updated; - option of using a 4 % step size for continuous conducted immunity test deleted; - revision of Annex A for telephony equipment including methodology for measuring the demodulation from a speaker/hands free device; - inclusion of new annex related to DSL equipment. The contents of the corrigendum of June 2011 have been included in this copy. This consolidated version consists of the second edition (2010) and its amendment 1 (2015). Therefore, no need to order amendment in addition to this publication.
OTHER PRODUCTS IN THE SAME STANDARD:
The fiber connector cleaning kit allows for cleansing the fiber optic connector to ensure reliable operation of the LSProbes and other Fiber optic products.
Spectral scan, spatial scan, peak-hold, continuous scanning, spectral and spatial comparison, scripting, limit lines, and report generation.
Spatial scan time:
Continuous real-time or sub-second single scan for the entire scan area is dependent on spectrum analyzer performance.
Spectral scan time:
