My lab notebook
Oscilloscope Lab Summary
- Summary of lab: basically, we practiced setting up and using an oscilloscope to get used to the online notebook and the equipment in the lab.
- Link to my notebook: August 29 lab notebook
- My values for AC fall time: I received three values for fall time by measuring the time it took for the voltage to drop to 10%: 52ms, 53ms, and 52ms. The average of these is 52.3ms. I'm not too sure what error bars are, but the standard deviation here is[math]\displaystyle{ \sigma=\sqrt{\frac{1}{3}\left( \left(52-52.3\right)}^2 + \left(53-52.3\right)^2 + \left(52-52.3\right)^2 \right)}ms=0.47ms }[/math]
- What I learned: I learned a lot about how oscilloscopes work and a little about editing a wiki. I don't really get the RC constant...
- Fun things I explored during lab: I pushed a lot of random buttons which did nothing amazing, but when I didn't plug in a ground cable into the function generator, the screen looked like the the waves moving in the ocean.
- how to make the lab better: hmmm... maybe say when this summary is due? It was very helpful when you explained the AC Coupling in front of the class. Maybe if you would have done the same for the RC constant things would have gone smoother.
