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HF News has been replaced by my new Twitter feed.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.

    Great Winter 2017 Seminars in Boulder City, NV!
    Learn and have fun, all at once at a beautiful, historic venue 22 miles from Las Vegas.
    Our instructors have a combined experience of nearly 200 years of practical problem solving!
    Get a break from the winter weather and come to sunny Southern Nevada for these events.
    • EMC Week: February 27-March 3, 2017
      instructor pictures
      Five days, four instructors for one of the most comprehensive treatments of EMC anywhere. Click here for more information. Topics include what to expect at the EMC Lab, pre-compliance testing, troubleshooting, PCB design, and materials issues.  There are lots of live demos during the week. Learning about EMC does not get any better than this and at a lower cost than most.

    • Lab Techniques, Design and Troubleshooting: January 30-February 1, 2017
      (also known as High Frequency Measurements and Noise in Electronic Circuits)
      picture of instructor
      Three days, one instructor covering great techniques to get your design working and finding defects that could become field failures. In addition, unique and powerful methods of troubleshooting EMC and ESD problems in minutes to hours instead of days to weeks or more are presented. Lots of demos on live circuits illustrate most of the main points covered. People have said this was the best course they have ever taken! Click here for more information. Low cost, and some travel expenses included.

    How do these seminars compare?

    The Lab, Design, and Troubleshooting seminar is my three day seminar on design, lab techniques, and  troubleshooting which includes about 1/2 day on EMC in designs, ESD in designs, and troubleshooting and measurement techniques in the design lab. I started this seminar years ago and constantly add and update it. A number of  people have said to me that it is the best course on any topic they and eveqr taken. Almost 50% of time is devoted to demonstrations. This year I have added a new section on exposing low probability failure modes that can present safety or other problems that can be a field disaster. There is content on my unique EMC/ESD troubleshooting techniques, but in addition, there is a lot of content on just getting the design to work in the first place or to troubleshoot it later on.

    Cost includes 4 hotel nights, 2 meals/day, and airport limo transportation in NV. Everything is covered upon arriving in NV except dinner each night. You only need a cheap airfare to get here.

    EMC Week covers EMC intensively with 4 instructors, one for each day, of which I will teach two days. This is probably the most comprehensive treatment of EMC that I have seen anywhere. Cost does not include hotel or other expenses (lunch is covered though).

    All are held in the Boulder Dam Hotel, a restored National Landmark Building that hosted the dignitaries who came to visit Hoover Dam during its construction. To visit the Boulder Dam Hotel website, click here.

    About Boulder City, NV

    Boulder City, NV is a small, quiet town that once was home to the workers that built Hoover Dam. There is plenty to see within a few blocks of the seminar venue shown in the picture below. It is located about 6 miles from Hoover Dam and about 22 miles from Las Vegas. Boulder City is the opposite of Las Vegas, but the glamor of Las Vegas is not too far away if you want to go there. I often say that being in Boulder City is like living in the 1950s but with very high speed Internet. Follow the links below for more information.

    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.

    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 or go directly to my papers, articles, and Technical Tidbits on this site!

    Check out one of my non-technical adventures, the Devil Dash, a footrace combined with an obstacle course (barbed wire, mud,  rough terrain, etc.). Click here to see the story. The event took place in Bootleg Canyon, here in Boulder City, NV March 23, 2013, on a much colder than normal day.
    I finished faster than 90% those entered, who on average were less than half my age (67), including finishing faster than 82% of the 20-25 year old group!

    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.

    Technical Tidbit - June 2016
    Measuring Current of a High Voltage Air Discharge

    Abstract: Special precautions need to be taken when measuring the current of a high voltage discharge. A specially designed target that balances insulating a current probe from the high voltage with minimizing inductance of the discharge path is described. Construction details are given.
