  6 years on and your 'deep dive' stuff is still pure gold, I wonder if the UNI's around the world use this in their curriculum..they should..cheers.

  Ignore anyone complaining about content being to long. youtube is littered with videos that dont' actually explain anything in any useful detail. You rock! I am a software guy for 30 years, between you, Mike, Bruce Simpson, Jeri Ellsworth and the young guys like Kevin Darrah and Jeremy Blum I am actually understanding the hardware that powers what I have been doing for a living since the 80's!

  Totally agree with Jens Andree. These kind of videos actually makes a difference in the world for a lot of people. Thx Dave....more of this stuff :)

  I love these long videos, how can people complain about free knowledge and content.

  That HP calculator induced memories. Highschool programming, iterating math & stuff.

  Thanks Dave, keep up the Fundamentals videos. I can't wait to get out to my lab and try this with my own scope..

  Wonder if you could do a video on ground loops? Thanks great channel!

  Dave, you may think 20MHz is an arbitrary frequency, but it is also the point where poor probing methods with long inductive probe ground leads start to cause extra ringing on fast logic causing measurement errors. &nbsp;<br><br>So for clarity 20MHz is for convenience when risetime induces false ringing from poor probing skills and gets a better textbook looking trace. &nbsp;<br><br>For ideal trace remove probe tip and ground clip and only use tip and probe ring to a pair of test pins or wires of similar spacing for convenience or use the coiled ground spring accessory . This gives the best results using a 10:1 probe.<br><br>Generally signals much less than 30MHz are used for this mode &nbsp;but logic rise times faster than 100ns ( most are) will get an overshoot proportional to the ground probe length and transition frequency resulting in ringing..<br><br>Tony EE since 1975

  Brilliant detective work and the explanation and demonstration is some of the best educational material available.
