Or TDS. Great video! Always dig the way you explain complicated concepts, you always crush it! Cheers!

This man just explained an extremely complex measurement setup and executed it in such a clear and concise way, that anyone can understand and grasp it! I wish that I would have had the opportunity to have you as my professor in college. BRAVO sir!! Fred

Thanks for making this video, very interesting and useful.

Always remember, a portion of your transmission will be reflected back to you.

Very well presented and explained. More to dig into!

Very interesting! Excellent explanations!

Thank you! Great as always. How can something so technical sounding as Time Domain Reflectometry be so darn easy to understand? Of course, when explained by a great teacher! It is so fascinating to know that I have the equipment in my home lab to measure the speed of light!

Great video Derek. I need to go back and look at mine again. If I remember, I didn't have the same wave form. Also, I didn't have a pulse gen at the time, and that might have been the difference. Hopefully, I did math right, it is a pretty simple formula.

[@AmRadPodcast]

In your case the return signal is stacked (summed) on top of the initial signal, which is still ongoing. In my case, the pulse generator goes hi/low before the return pulse, so you see two individual blips.

Have done similar on site with high voltage cables

Thanks for your video. Would it work with a rise time < 20 ns? That's the best my frequency generator can get (FeelTech FY3200S)
