Digital Oscilloscopes, Capacitor Banks, and Loud Bangs – Oh my.
Posted by aonomus on April 18, 2011
I just finished my entry for the Tektronix Oscilloscope Video Contest and uploaded it to youtube, the premise being that measuring a 10kA pulse power discharge is (as you would imagine) challenging. Having a digital storage oscilloscope (DSO) makes it much easier.
You can view my video entry on my channel on youtube below, but once you do, please do vote for my entry daily at http://www.mytektronixscope.com – help me win a primo DSO so that I can further my capabilities for research.
