Welcome to Cherry Clough Consultants
Independent consultants who help designers, manufacturers, system integrators, installers, users deal quickly and cost-effectively with real-life interference (EMI), or compliance with EMC and Safety Directives and similar regulations worldwide. All applications, all industries, all sizes/scales.
Our SI, PI & EMC design techniques have been very well-proven for 26+ years to significantly reduce design and development time and cost; overall cost of manufacture; warranty costs, and financial risks, at all frequencies up to 24GHz (so far!) – whatever the relevant EMC standards: from the 'generics' up to the toughest, such as DEF STAN 59-411 Land Class A.
And our well-proven guidelines for reducing the Functional Safety (and other) risks that could be caused by EMI have now been standardised by both the IET and the IEEE.

New free EMC magazine: EMC AWARE
This new magazine makes free information on EMC, its technologies and test equipments; events, job adverts, etc. available to all. It also has the famous Banana Skins column, now up to number 930!

The archive of the popular EMC Journal has been rehosted
All issues of the EMC Journal, and much else associated with that very successful UK EMC magazine, are archived, but problems with hosting have made them unavailable for a year or so. But now they are back on-line! Visit: www.theemcjournal.com or www.compliance-club.com
Keith Armstrong's training coursenotes now available for on-line purchase
These updated PDFs include detailed change records so you don't have to read through them to find the updated material.
This way of learning good EMC design is better than buying textbooks (which are out of date for years) or attending annual training courses (where most of the material is the same as the year before, you can't simply attend the new or improved material).
emcstandards.co.uk

Keith Armstrong's textbooks
From October 2018 this is the new site for ordering my books, and some others.
My books are colour-printed 'on-demand' and are not available new from Amazon or other resellers, who might 'mistakenly' list them as being out of print.
