Achieving Compliance With The European Community EMC Directive
IEE Colloquium on 'Achieving Compliance with the European Community EMC Directive' (Digest No.126)
IEE Colloquium on 'Achieving an Acceptable Confidence Level in EMC Measurements' (Digest No.117)
Risk assessment for BCI testing
A system-level test method has been devised that uses all measured transfer function information, thus giving statistical information on the possibility of over or under testing a component. This statistical information, comprising mean and...
The effects of variations in wave impedance in the coupling of large lossy bodies to external electromagnetic fields
Describes a theoretical analysis of the illumination of a hollow, conductive object containing a wire by a non-planar wave. Much EMC testing is performed at antenna-test object separation distances that are small compared to the wavelength....
Reproducibility and relevance in current injection testing
Immunity testing by current injection onto system cables is an economically attractive alternative to radiated field testing, but correlation between the two has proved difficult. The basic characteristics of the two methods are reviewed as...
The effects of wave polarisation on the performance of radiated emission measurement test sites
Presents a simplified analysis of the coupling between an EUT (equipment under test) and the antenna for any radiated emission test site. The analysis illustrates the problems with inter-site comparison.<<ETX xmlns:mml="http://www.w3.org/19...
Reducing the uncertainty in EMC measurements due to chamber characteristics and system mismatch
Examines the sources of uncertainty in EMC measurements carried out in the EMC Test House Facility at British Aerospace (Dynamics) Limited, Filton. The dominant sources of error are identified and ways of reducing these in order to minimise...
Radiated emission measurements in screened rooms; techniques for the reduction of calibration uncertainty
Describes the measurement tools, and also a preliminary calibration technique which, in favourable circumstances, enables screened room measurements in the 1-30 MHz frequency range to be used to predict free-space radiation from the simulat...
The status of NAMAS accreditation for electrical calibration laboratories
RF measurement accreditation is essential for providing acceptable traceability to UK industry, and it is therefore very important that the country has sufficient accredited laboratories to provide this facility. With the limited number of ...
