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 are very well-proven for 25+ 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' to the toughest such as DEF STAN 59-411 Land Class A. 

We have well-proven guidelines for reducing Functional Safety risks that could be caused by EMI.

Most of our on-line effort is now going into our new website emcstandards.co.uk, why not visit?

Keith Armstrong's training courses now available for on-line purchase
The updating versions will be complete with change records so you don't have to scan right 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This way of learning good EMC design is better than buying textbooks (which are out of date for years) or attending annual training courses (where most of the material is the same as the year before, you can't simply attend the new or improved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, and you have to pay full price again).

The new site for easy and free access to the huge range of Keith Armstrong's published material, and a lot of additional stuff such as EMI Stories, EMC Design Checklists, Webinars, and more.

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'. 
They are not available new from Amazon or other resellers, who might mistakenly list them as being "out of print"
