Programme tests EMC lab consistency
ACIL is launching the fifth cycle of its EMC round robin programme using a test artefact for the comparison of radiated emissions measured on an open area test site in the frequency range of 1-18GHz.

Test artefacts check EMC lab accuracy
ACIL's ongoing programme offers two different artefacts to address both radiated and conducted commercial EMC emissions measurements.
Engineers and technicians must be trained
Leading UK engineering and technology firms, with a combined multi-million pound spend on training and development, will assemble at the IEE 'Investing in Technical Teams' forum on 4 November 2004.
Workshop gives complete picture on CE.NET 5.0
A UK-based workshop will give embedded software development engineers hands-on experience in running the new 5.0 release of Windows CE.NET on next generation processors.
The test artefact is a comb generator, providing narrowband emissions at fixed intervals from 1 to 18GHz and beyond.
Emissions measurements above 1GHz are increasingly common with the advent of fast processors and wireless devices in the 2.4 and 5GHz bands.
The cycle is intended for: any laboratory interested in using an interlaboratory comparison programme to assure the quality of test results in accordance with 5.9 of ISO/IEC17025; test laboratories that participated in the prior 1-18GHz study and that wish to revisit some of their measurements based on the published data; and test laboratories that did not participate in the prior study and that wish to identify and reduce their sources of measurement error.
ACIL round robin programmes involve circulating a calibrated test item successively from one lab to another.
Each round robin cycle is limited to a group of ten laboratories.
on completion of the 10 laboratory cycle, programme results will be compiled and published by ACIL with the identity of each individual participating laboratory remaining confidential.
ACIL's programme is operated in accordance with ISO/IEC Guide 43-1, Proficiency testing by interlaboratory comparisons - Part 1: Development and operation of proficiency testing schemes.
Interlaboratory comparison or round robin programmes are stipulated in ISO17025 as one method of assuring the quality of test results.
Both NVLAP and A2LA require accredited laboratories to participate in such programmes where they exist.
The cost is $800 for ACIL members and $1500 for nonmembers, payable at the time of registration.
The test object will be available for week-long testing beginning on 16th May 2005.
