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 is my email newsletter to inform visitors of this website when significant new content is added and for important news related to the website or to high frequency measurements and design. There is no charge to sign up for this email service and it will not contain paid advertising. The list will be kept confidential and will not be disclosed or sold to anyone. To sign up via email, click here and put "hf news" in the subject line. The number of email messages will be limited to one or two per month. Most months there will be only one message.

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.

    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

    CircuitAdvisor.comis devoted to engineering information and training delivered through video and audio multimedia as well as written text. The site is being rebuilt as a training and resource site for companies that desire group subscriptions to provide their engineers with a useful resource that will reduce design problems and help insure a smooth rollout of products at a very low cost.   Contact me for more information.

    I finished faster than 90% those entered, who on average were less than half my age!

    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 - September 2014
    Human Metal Model ESD Compared to Direct Skin Discharge (Human Body Model) ESD
    (
    Revisited in Video Format)

    Abstract: There are two models of human generated ESD that are widely used. These model a human holding a piece of metal (HMM) and a direct discharge from human skin (HBM). Using radiated induction into a shorted scope probe as a measure of the severity of an ESD event, these two types of human discharge are compared on live video. It is shown that even a small piece of metal being held in a hand can significantly increase the intensity of an ESD event.

    Technical Tidbit - August 2014

    Radiated Emissions Can be Strongly Affected by Driving Signals, A Problem for Emissions Testing
    (An Example Using a Class D Stereo Audio Amplifier
    )

    Abstract: Radiated emissions from electronic equipment can be a strong function of how the equipment is operated. In the case of class D audio amplifiers, the audio signal driving the amplifier can have a large effect on emissions. Test results and implications are discussed as they relate to the philosophy of radiated emissions testing.
