Welcome to my High Frequency Measurements Web page. Below you will find links to interesting technical goodies for download, as well as other interesting websites, information on my seminars, and much more. I will be adding to this site weekly, so check back occasionally. Feel free to print out pages on this site and to give them to others, but I ask you to include the complete page with header. Check out the monthly Technical Tidbit article linked at the bottom of this page. Each one will illustrate a design or measurement principle, sometimes what not to do.

HF News has been replaced by my new Twitter feed. Just go to http://twitter.com and follow me at @dougcsmith_ee . I usually post short items such as interesting technical links once or twice per day.

Design and Troubleshooting Tips and Techniques: You will find many tips on design and troubleshooting on this site, yet what you see is just the "tip of the iceberg" compared to what is available in my on-site private seminars. The seminars cover many effective design and troubleshooting techniques developed by myself and not taught anywhere else!  Click here to request more information via email.

    Design Troubleshooting, EMC, and ESD in Boulder City, NV!
    --------------------> February 22-24, 2016 - Registration os Open! <
    Registration form link
    One of the best seminar venues in the industry with some people staying on after the seminar to see the area.
    The seminar fee includes your hotel room for up to 4 nights, 2 meals/day,
    and local transportation to/from Las Vegas McCarran Airport and the Boulder Dam Hotel via private limo (22 miles)!

    The combination of the material presented, the venue, and the passionate presentation will likely make for the best technical short course/seminar you have ever taken! Didn't think a technical presentation can be passionate? This one is. The result is this short course/seminar
    will likely be the most informative, practical, and FUN seminar you can attend.

    New Addition: There will be a vendor show in conjunction with the seminar showing some of the equipment I use in the seminar!

    New topics and features added added in 2014-5:
    1. Expanded section on switching power supply and class D amplifier noise
    2. A new form of ESD/EFT generated by system power supplies (how your system can take itself out)
    3. Analyzing systems as a collection of resonant, tuned circuits for robust design and troubleshooting
    4. Effects of radio frequency signals on analog circuits
    5. EMC test lab errors that can spoil your day (much more common than you would think)
    6. Simple antenna theory for troubleshooting EMC problems (leading to using your index finger as a useful troubleshooting tool)
    7. Vendor show
    This seminar, and its demonstrations, are the product of a lifetime of experimentation and electronic design, 55+ years of electrical engineering (starting at age 12). Major concepts discussed in the seminar are illustrated with experiments on live circuits that were developed over years and are quite unique, enabling a deeper understanding of engineering concepts than seminars usually do. Many new topics and experiments have been added over the last few months that engineers and technicians will find very useful in producing, testing, or debugging new and existing designs of ALL types. No other seminar illustrates principles of design with experiments like this seminar does! Using the techniques presented in this seminar, design problems can be found and fixed in a few days, not weeks or months that are typical in the industry, not to mention being able to avoid the problems in the first place.

    Seminar Testimonials
    Here is a recent testimonial:
    "Your seminar still rates as one of the most educational experiences of my life. It was awesome." KC Armstrong

    This three day seminar takes the best points from my seminars and compresses them into three action packed days with lecture, video, and many demonstrations on live circuits. Time is allowed for attendees to operate the experiments if they want. In two days, you will learn how to make accurate measurements in the lab and then apply those techniques to design verification and troubleshooting as well as EMC problems. The techniques and experiments are geared to the development lab and common equipment found there. During an optional third day, ESD/EMI at the system level will be covered as well as applying system level ESD stress to components, such as LEDs, in a test environment. Click here, for an outline of the seminar. This seminar is derived from the following seminars and is composed of the best points from them to make the best use of your time. All attendees will receive a USB thumb drive with a pdf copy of the notes on it as well as other useful technical information.

    In addition, the seminar fee includes (for the same price that other seminars in the field cost for just the seminar and lunch):
    1. Round trip transportation by Lincoln Towne Car (or equivalent) to/from Las Vegas McCarran Airport and the Boulder Dam Hotel
    2. Up to four nights in the historic Boulder City Dam Hotel
    3. Breakfast and lunch each day
    4. Tuesday evening dinner reception
    5. A PDF electronic color copy of the notes on a USB thumb drive including other useful technical information.
    6. A one year membership in the Boulder Dam Museum for unlimited visits to the Boulder Dam Museum, discounts at the Boulder Dam Hotel, and more.
    You just have to get to Las Vegas McCarran Airport and I take it from there except for dinner on Monday and Wednesday.

    During your stay, walk around town and experience the scenic, quaint town of Boulder City, NV. Boulder City is like living in the 1950s but with high speed Internet! However, the glitter of Las Vegas is only ~20 miles away.

    This seminar combines features from the following seminars into three days. Seminar Outline

Hotel, NV airport transportation, and most meals are included, and yet, these seminars cost no more than most public seminars. Previous people attending have rated these seminars as the best they have ever taken! There are no lengthly forms to fill out, just contact me by phone or email for details or to register. To see testimonials, click here

    Contact me if you are interesting in having a semi-private "seminar-on-demand" for your company in Boulder City or on-site at your company location. The material can be custom tailored to your interests from topics you see on this website for groups of 2 to 8 on short notice. Click here to send an email requesting details. I can also arrange a session in Boulder City to troubleshoot your design on my test bench for small products.

    Webinars on Targeted Topics To Avoid/Fix Design Problems!

    Click here, to see descriptions and registration information on my one hour webinars than can solve difficult design problems quickly. Touching on topics like signal integrity, EMC, ESD, and general analog and digital design, these webinars are a quick way to get your design working. There are public presentations most weeks as well as private presentations on demand with a new simplified, lower cost price structure. New webinars are added periodically.

    Next up, time to be set soon:
    Electrical Resonances in Physical Structures
    (A novel approach to solving analog and digital design problems with application to SI, EMC, and ESD issues)
    New material added that leads to a surprising design rule for PCBs of four or more layers!

    If you have ever encountered EMC, ESD, or Signal Integrity problems, there are innovative techniques in this webinar that can shorten debug times significantly.
    • Click here for an outline and description (lots of new material added in the last two months including a live demonstration on a PCB).
    • Click here for a registration form
    •      Thinking of an electronic system as a collection of coupled tuned resonant circuits is a novel way of approaching a system design from ICs, to PCBs, to cables, to entire systems. This approach can expose design problems and fixes for operational, SI, EMC and ESD problems and applies to both analog and digital designs. Every design engineer needs to attend this webinar! EMC engineers will also find this webinar very useful in their work as well.
    The cost is lower than most webinars at $120/person capped at $600 per location, so that even individuals can afford to attend that will not be reimbursed by their employer. If you have several people that can attend, the cost becomes very low per person. Private delivery for a group is $600.

    Doug at the Mic

    You can find lots of audio and video podcasts on various topics of technical interests. Most of them are from a few years ago and were on my paid website emcesd-p.com but are still current and useful, and now free. I will be adding podcasts regularly in the future. This has been made possible by the continuing decline in costs of bandwidth. Click here to go to my podcast page.

    Have a tough design problem? Design problems can be very costly. Even if caught in the lab, precious resources can be wasted tracking such problems down. My private seminars cover design and troubleshooting techniques I developed that are not taught by anyone else! These techniques have solved tough problems in a day or two after design teams had struggled with the problems for weeks or months, not to mention avoiding the problems in the first place. Click here to request more information.

    Design troubleshooting and verification: Tracking down design problems in the lab can be time consuming. My public seminars and my private on-site seminars include new information to minimize debug time. The difference can be hours to a solution instead of weeks! Click here to hear a 1 minute, ~128K, audio clip discussing the seminar.
