Resources, Books & Training

Areas of EMC to Master

EMC is a huge subject, so many engineers can and do make an entire career out of just a subset of it.

Some people focus on the testing aspect, some focus on regulations, some on design and troubleshooting. With so much to learn, it's easy to see how the guys who are really good at this stuff are often coming up to retirement!

Below is my take on some areas of EMC. I've seen other categorizations that come at it from other viewpoints, but as a hardware engineer, this is how I visualize it.

Branches of EMC

Many of these subjects can be a whole career on their own. It's one of the reasons I like EMC so much - there are always more interesting things to learn!

Test & Measurement



Testing and compliance engineers have a good appreciation for rules & regulations as well as what it takes to make accurate, repeatable measurements. As frequencies increase, this becomes more challenging.




2d and 3d EM simulation programs are still fairly niche and expensive, but several companies do specialize in this area (see below). Used extensively in the aerospace and automotive industries where getting things right up front is crucial.

Immunity DFC



Related closely to emissions DFC, but with some extra considerations to take account of, design for immunity compliance is extremely important for many types of products in including medical, automotive, aerospace, military etc.. as well as most electronic products destined for Europe or Australia.

Pre-Compliance Testing



Pre-compliance testing involves early testing of units to give an idea of EMI/EMC performance. Often manufacturers set up their own in-house test setups and engineers must learn how to make reasonably accurate measurements to roughly approximate results from an accredited 3rd party lab.

Signal Integrity



Of course SI is a huge subject. Specialists here can dive into high speed board design and simulations. This area is only going to grow as CPU speeds and memory busses continue in to the GHz regions.

EMC / EMI Troubleshooting



Based on a foundation of hardware design, physics and test & measurement, EMC troubleshooting is a wide and interesting subject. Rarely do you find an identical set of EMC issues and design constraints, so this subject involves problem solving and creativity.




Even at the IC level, almost more-so, EMC must be taken into account. On-chip capacitance allows for a small but very low inductance source of switching current. ICs can also integrate transient immunity protection although additional board level components are often also necessary. Control over these aspects is very much the domain of ASIC design engineers.

Power Integrity



PI is also an interesting and growing field of study and application. It’s mainly concerned with how in the world to deliver tens of amps at extremely low impedance to satisfy modern IC current switching demands.

Emissions DFC



Designing circuit boards with EMI/EMC compliance in mind from the outset is in itself a huge area. With many textbooks (see below) and courses to choose from, there’s no shortage of ways to improve your knowledge in this area.

Systems & Installations



On a larger scale, EMC can and must be applied to larger objects like cars, trains, planes and even buildings. With unique challenges around cabling, shielding and the safe operation of many electrical modules/devices within a larger system, this area requires another special skillset.

Regulatory Compliance



At larger hardware organizations and 3rd party test labs, often there will be staff or departments dedicated to regulatory compliance. This may involve things like determining applicable standards, ensuring ongoing compliance with updated rules & regulations as well as dealing with compliance impact of product changes.

Where are you in your career continuum?

Given the vastness of the EMC topic, it's unreasonable to expect to learn it all at once. Typically an engineer will learn bits and pieces over time and by the end of their career they eventually have an expert understanding of the subject.

Why 'Learn and Burn' Methodology Doesn't Work For EMC

Hardware engineers like to taunt software engineers for many reasons, but one of them is that they get the luxury of correcting mistakes during the development phase pretty much on the fly. Doesn't compile? Fix error - re-compile - done!

For hardware engineers, of course we try to catch as many functional problems as possible before pulling the trigger on manufacturing a PCB. But the time to identify and remedy a functional hardware issue can be in the order of weeks. We learn lessons, but the feedback loop is much longer than for software engineers.

Because EMC testing typically happens much less often than individual functional PCB spins - maybe twice or 3 times at a well prepared company, or maybe just once at a company who are new to the process, the feedback loop for EMC issues is much longer than for even PCB spins.

And if your product fails EMC, maybe you spend a week or two debugging the problem. So for example, in a period of 6-12 months, you've debugged 1 or 2 EMC problems and learned the theory and lessons that go along with solving those problems.

Given the myriad number of ways to accidentally create an EMC failure mechanism, having an opportunity to practice from failures (learn and burn) only a couple of times a year, is going to make the process of mastering EMC a very long one.

David vs. Goliath

Rules for EMC apply regardless of the size of your company. Do you think the FCC cares if it's a small startup or a multinational's products that cause a radiated emission problem? They don't, so unfortunately regardless of a company's size and how many products they ship per year, the rules still apply.

But when it comes to preparing a product for testing, the big guys often have a huge leg up on small manufacturers.

Here are some of the ways I've noticed things being done differently when working with various size manufacturers:

So you can see that in terms of chances of passing EMC testing much quicker, the odds are stacked in favour of the larger manufacturers.

Small manufacturers often either don't know about the challenge they're facing, or don't have the resources (financial, manpower, time etc..) to implement processes to deal with the issue.

But, using the resources outlined in this beginner's guide, engineers from all sizes of manufacturers can map out an individualized path to improving knowledge of the subject.

Application Note Resources

These are some useful app notes I've collected over the years. Hyperlinks often go dead, so rather than continuously update the links, these resources are locally hosted. I do not own the copyright to these, so if you are the owner of any of them and want me to take them down, just email me. All branding has been preserved.

Top 5 Recommended EMC Textbooks

EMC textbooks offer a shortcut to getting a career's worth of knowledge in the subject. For less than the cost of 1 hour in a 3rd party test lab, you can learn what took these engineers years or decades to learn through hard fought battles with EMC. Seems like a good deal!

  1. Hi Andy,

    I was an EMC test engineer (4 yrs.) and then an EMC design engineer for Cisco Systems in San Jose, CA for 18.5 yrs. and I retired in 2011. I now would like to come out of retirement and I think that I would like to work again in EMC testing. Do you have training that would allow me to apply for EMC testing positions? I am not affiliated with any company. Specifically, I am interested in the cost of any potential training for someone who is not affiliated with any company.
