How to use an oscilloscope to make measurements on an ultrasonic transducer system

In this webinar recording, I demonstrate the most required skill when working with ultrasonic transducers - how to use an oscilloscope. This is practically the only way to measure and interpret ultrasonic transducer performance. Its use is priceless in troubleshooting and design.
