This is part 2 of 2 on lab scope basics where I cover the relationships between time base, sample rate, and the waveform buffer.
00:00 - intro
00:21 - waveform buffer
01:45 - high sample rate = reduced record time
04:54 - downside of too high a sample rate
08:43 - time base effect on sample intervals
12:22 - live example (ignition coil primary)
15:47 - scope aliasing (not enough samples)
18:18 - long time bases require an increased sample rate
19:59 - how to increase buffer size (frames)
20:27 - setting a scope for detail and repetition
21:25 - time base vs sample rate
23:42 - ignition primary captures on a long time base
26:38 - vertical and horizontal zoom
28:25 - Hummer Part 6 video 2008 Hummer H3 Misfire Case Study (Pa...

For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
Want even more diagnostic training? Whether you are a DIY trying to fix your own car, someone looking to become an auto technician, or a current auto technician that wants to get more into diagnostics, subscribe to ScannerDanner Premium https://www.scannerdanner.com/join-sc... There is a 14 day free trial.
On ScannerDanner Premium I will bring you right into my classroom at Rosedale Technical College. You will find page for page lectures taken right from my book as well as exclusive classroom type case studies. What is so special about these classroom case studies? I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. There is no better on-line training of how to troubleshoot automotive electrical and electronics systems anywhere!
