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.

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

...News – April 2020... 

COVID-19 - Business as Usual ! (well, with a lot less travelling)
We are still providing EMC, SI and PI design reviews & fixing, and our world-famous training courses, using a mixture of videoconferencing, email, text, phone (and even fax).

Why not use the lockdown to progress new product design/development with everyone working from home offices – there's no reason to stop any design/development projects, even as regards EMC! We can even do some EMC pre-compliance tests ourselves.

EMC & COMPLIANCE INTERNATIONAL 2020 postponed to 2021 !!
EMC-UK is coming home to the revamped Newbury Racecourse: 19+20 May 2021
In co-operation with EMC Standards, this independent event has been re-launched as "EMC & Compliance International", and will include:

  • Two days of Training Workshops by Keith Armstrong
  • Two days of Technical Workshops
  • TWEX (Ten minutes With an EXpert) – a totally new type of activity!
  • A presentation by an IEEE EMC Society Distinguished Lecturer from the USA 
    at an evening event with free canapes and drinks
  • Plus of course the famous exhibition

If you are in the EMC or Compliance business, this event is not to be missed!

Keith Armstrong's training courses now available for on-line purchase
The updated versions include detailed 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This way of learning good EMC design is better than buying textbooks (which are out of date for years) or attending annual training courses (where most of the material is the same as the year before, you can't simply attend the new or improved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).

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.

For what we used to call "EMC for Functional Safety": 
The IET’s Code of Practice on Electromagnetic Resilience
First published February 2017, the successor to the IET’s 2013 guide:
“Overview of techniques and measures related to EMC for Functional Safety”

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.
