Update on Activities

Hi All,

Free EMC Guides – This last year, Interference Technology (IT) has posted several free downloadable guides to EMC. Some of the more recent ones include EMC Fundamentals, EMC Test, Medical EMC, and Military & Aerospace EMC. We’ll have a new 2017 Automotive EMC Guide coming out this week, as well. Please review all these at the bottom of our web page: http://www.interferencetechnology.com.

Looking for Authors – We’re looking for authors! IT has a long history in publishing the very best technical articles and reference material in the field of electromagnetic compatibility. It was first published starting in 1971 and I actually started subscribing to it in the mid-1970s – well before I knew I would end up in a career as an EMC engineer and consultant. Now I find myself as editor of that same publication – a humbling responsibility. You’ll find our Author’s Guide under the link, “Contribute”, at the bottom of the home page.

May Seminars – In other news, May was a busy month for seminars, with presentations in Chicago, Detroit and Israel. I was honored to be the featured speaker for the IEEE EMC Society in both Chicago and Detroit, and then was off to Israel to present a tutorial on Radiated Emissions Troubleshooting at DGCON (similar to DesignCON).

Upcoming Seminar – I’ll also be scheduling my regular two-day intensive EMC design, theory, troubleshooting, and pre-compliance testing seminar in Longmont, Colorado this coming September 19-20, 2017. This time, I’ll have guest speaker, Eric Bogatin, who will present a segment on “Power Distribution Network (PDN) Design for Low EMI”, based on his recent book on the topic. Should be a great program! Info and registration here: https://www.nts.com/resourcecenter/events/seminars/emc-essentials#

Webinars – Finally, for all of you who live outside the U.S., or who are unable to travel to one of my EMC seminars, this is for you! Washington Labs is hosting webinar presentations by myself, Robert Hanson, and Steven Ferguson on EMC Design & Troubleshooting. More info and registration here: http://wll.com/academy/2017-Webinar-Series-EMC-Design-Troubleshooting.html

That’s all for now, stay tuned for more!

Update on my activities

Hi All,

Sorry there’s been such a lapse since the last time I posted. Having accepted the position of senior technical editor for Interference Technology (IT) last December has kept me drinking from a firehose, as they say. Since the first of the year, IT has published my Real Time Spectrum Analyzer Guide, a free download on the web site: http://www.interferencetechnology.com. We also released the first of two print reference issues this year, the 2016 Directory and Design Guide.

IT has a long history in publishing the very best technical articles and reference material in the field of electromagnetic compatibility. It was first published starting in 1971 and I actually started subscribing to it in the mid-1970s – well before I knew I would end up in a career as an EMC engineer and consultant. Now I find myself as editor of that same publication – a humbling responsibility. Please register at the web site to start receiving our newsletters and notification of future guides on various fields of EMC. We’ll be releasing guides to Military EMC, EMC Shielding, EMC Filters, and Automotive EMC throughout the rest of this year.

In other news, I’ve had to halt my blogging for EDN.com, as the columnist for “The EMC Blog”, since taking the reins of IT. Fortunately, my good friend and colleague, Arturo Mediano, a professor and consultant from Spain, has agreed to start up the blog again in my place. He’s a brilliant EMC engineer and instructor and will bring a whole new take on practical EMC design and troubleshooting. Check it out at http://www.edn.com, then click on Communities > Blogs, then scroll down until you find “The EMC Blog”.

I’m scheduled to help teach a one week course during the next “EMC Week in Boulder City”. My topic will be EMI Troubleshooting and Pre-Compliance Testing. Check out the details and register here: http://www.dsmith.org.

I’ll also be scheduling my regular two-day intensive EMC design, theory, troubleshooting, and pre-compliance testing seminar in Longmont, Colorado this fall. Stay tuned for dates and pricing.

Finally, for all of you who live outside the U.S., or who are unable to travel to one of my EMC seminars, this is for you! I just completed the development of an intensive ON-LINE six-lesson course, EMI Troubleshooting and Pre-Compliance Testing”, which will be hosted by my friend Andy Eadie. The lessons are streamed as a video and may be viewed unlimited times. The cost is just $995 and full details and registration can be found at http://www.emcfastpass.com.

That’s all for now, stay tuned for more!

Really Small Drill Bit Set

For those of you who could use a set of really small drill bits, you might consider this set that ranges from 0.3 to 1.2mm in diameter. The cost is just $3.99 at Amazon. The company selling these is based in Asia, so the shipping time is about three weeks.

Pros:

They come in a very nice plastic case and the bits themselves are cushioned.

They fit the 1/8-inch jaws of a standard Dremel tool.

Cons:

The size markings are etched into the shank, so are difficult to read until just the right angle of light hits it – a magnifying loupe is a plus. They thinner bits break very easily, so it’s best to use a sturdy drill press for these, rather than a Dremel tool.

2014 Blog Highlights (Part 1)

Sorry about getting a little behind in postings. Here are some of the highlights of postings on the EDN.com site:

Review: inexpensive RF generator – During one of my presentations on low-cost EMC troubleshooting tools at the IEEE EMC Symposium last August, one of the attendees, Doug Miller, mentioned a small PC-controllable RF generator for just $190. Of course, I had to buy one and try it out!

Review: Windfreak Technologies SynthNV RF generator – Every once in a while, I discover a product that is so incredible I wonder why it hasn’t been publicized more widely. This is the case with Windfreak Technologies $599 miniature RF generator, the model “SynthNV” (Figure 1). In case you’re wondering, their company is named after the owner’s sailboat!

Detecting ESD Events – In my experience, electrostatic discharge (ESD) issues have now become the second-most prevalent issue other than radiated emissions. If you find your product has exhibits random upsets, such as loss of data or unusual circuit resets, it could very well be caused by ESD. This article describes several methods to detect these events.

Harmonic Analyzer Tool – Because of their typically fast edge rates, crystal oscillators can generate a large number of high-order harmonics. This harmonic analyzer was created by my coauthor, Patrick André, with additional formatting tweaks by myself. I find this really handy to calculate harmonics from clock oscillators.

Review: TTi PSA2702T handheld spectrum analyzer – One thing that I find handy is a small hand held spectrum analyzer for use in troubleshooting EMI issues. As I travel a lot in my job, I like to take the minimum amount of test equipment possible. Unfortunately, most good quality analyzers are large, heavy and expensive. About ten years ago, I ran into the Thurlby Thandar Instruments (TTi) PSA2701T and have used it extensively since then. During that time, I reviewed it several times. In May 2013, TTi completely redesigned and repackaged this analyzer and released it as the PSA2702T. This is a review of the new PSA2702T, which I have used for several months now.

2013 in review

The WordPress.com prepared a 2013 annual report for my EMC blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 11,000 times in 2013. If it were a concert at Sydney Opera House, it would take about 4 sold-out performances for that many people to see it.
