Oscilloscope Triggering: HDDG #22 Presentation

Pinterest LinkedIn Tumblr

During #22 of the Hardware Developers Didactic Galactic meetup, I discussed Oscilloscopes. (Previously James talked about capacitors.) In the presentation, I broke down the internals of an oscilloscope. The presentation started off with a block diagram. Then I discussed the main components: vertical amplifier, A/D, memory controller, some of the computer side stuff, and the keynote was on triggering.

The trigger circuit of an oscilloscope fascinated me since very early in my HP/Agilent career. When I saw trigger modes like Pulse, Violation, Rise Time, and “Runt,” I thought: Wow, this must be the most complicated circuit in the scope! While it isn’t trivial, it very clever how just a few pieces of (relatively) simple hardware drive one of the most important aspects of a digital scope.

Rick Altherr also gave an excellent talk on ECUs and their sensors. (I always thought ECU only meant engine control unit. His talk helped me understand why that isn’t really the case anymore!) It was great to learn about the combination of the engine mechanics with the electronics that control it. !)
