Oscilloscope Lab Summary

--Linh N Le 14:57, 31 August 2007 (EDT) 1. Brief summary of what you did (linking to the lab manual page is OK)

I tried to follow the lab notebook as best as I could. 
I had to be "creative" on some spots, since I had to work with different equipment.

2. Report your value for the fall time using AC coupling.

For the AC coupling, and using the "Measure" function of the scope, and manually with
the "Cursors" I got a fall time of 1.08ms.My time is a bit low compared to the others 
in the lab (about 60ms), so I should redo these measurements (if this was a real lab)

3. Include error bars!

 My measurements are so far off, that It wouldnt be worth discussing the error.
The data must be retaken 

4. Explain how you measured this (briefly)

 Using the "Cursors", I measured the time interval between the peak of the sqaure wave
and %10 from the bottom of the wave. To find the %10 mark, I measured the voltage of the wave
and lined up the %10 mark on the time measurements.Perhaps the measurements mave have been 
much better if I played with the resolution of the scales better (as Dr. Koch showed me during his "quiz").

5. What did you learn?

 I learned how to use an Oscilloscope and got to mess around with the Heathkit 

6.* It's OK if you didn't learn anything. But include things you are still confusing.

After having the "quiz" with Dr. Koch, I got a better feel for the machine, so if I had to do it again, it would be a much better run.

7. What did you explore outside of the standard lab procedure? Anything interesting?

 I tried to play with the XY mode to make cool patterns, but my heathkit had no settings to
change the voltage easily 

8. What could make the lab better next year?

 Shorter lab, more time to play around, and enough equipment for eveyone
