to CISPR 12. Your could try to come and visit us at our lab in St Marys, NSW while we test a lot of commercial and military stuff, apart from development work on reverberation chambers. Unfortunately, we cannot release procedures as they are proprietary. Regards Arun Kaore ADI Limited

FW: broadband narrowband emissions

, MIL STD 461D and most commercial standards have got around this NB/BB emission discrimination mess by specifying the measurement BW. Hope this helps. Regards Arun Kaore EMC Engineer ADI Limited Test

FW: Amplifier for measurements above 1GHz

only. A zoomed in measurement from 3m to 1m to beat the noise floor is not recommended as the antenna and EUT dimensions become critical. Hope this helps Regards Arun Kaore EMC Engineer ADI Limited Test Evaluation Centre Forrester Road, St Marys NSW 2760 P O Box: 315, St Marys NSW 1790 Tel

FW: Equipment Produced in Series

where one forgets about the use of LISNs and shudders at the thought of using a HV probe. Cost of such stringent EMC testing will almost inevitably be built into the contract. Regards Arun Kaore EMC Engineer ADI Limited Systems Group Test Evaluation Centre Forrester Road, St Marys NSW 2760 P O

Reliability MIL HDBK 217

Hello all I am overwhelmed with the help I got from you all, this short note is to express my thanks !! Regards Arun Kaore EMC Engineer ADI Limited Systems Group Test Evaluation Centre Forrester Road, St Marys NSW 2760 P O Box: 315, St Marys NSW 1790 Tel: 61 2 9673 8375 Fax: 61 2 9673 8321

RELIABILITY TO MIL-HDBK-217

Hi all, Could someone guide me on where to down load from the net or purchase the latest version of MIL-HDBK-217 and approximately how much it would cost. It is a Reliability/MTBF related issue. Thanks in advance. Regards Arun Kaore EMC Engineer ADI Limited Systems Group Test Evaluation

FW: Root Causes of NSA non-compliance

, at the end of the day, just because the site attenuation of any site is accurate, this does not mean that the measurement uncertainity has come down or that the EMC tests that are carried out on the site are equally accurate (nothing to do with the lab or personnel!!) . Regards Arun Kaore EMC

Re: NEAR/ FAR FIELD CORRELATION ISSUES
