I used oscilloscope and write a formal lab repoet.

Summary

SJK 12:52, 29 September 2010 (EDT)
12:52, 29 September 2010 (EDT)For future labs, you will report results along with statistical uncertainty.  For example, "52 ms +/- 1 ms, where 1 ms is the standard error of the mean of 5 measurements."  You will also compare results with accepted values and discuss systematic errors.  That was tough to do for this lab, but will be important for future labs.

  • Report your value for the fall time using AC coupling.
 Fall time("measure" functions):86.58ms
 Fall time("read"): 52ms (about 5 intervals, each interval is 10ms)
  1. Include uncertainty in your measurement!
    • Can't read to decimal place. And 52ms is estimated by counting intervals.
  2. Explain how you measured this (briefly)
    • Count how many intervals between 10% of the peak voltage to 10% of the lowest voltage.

Questions

  1. What did you learn?
    • I learned how to use oscilloscope and do open physcis.
  2. What did you explore outside of the standard lab procedure? Anything interesting?
    • Nothing I think. I want to try the last part, but I don't have another free function generator.
  3. What could make the lab better next year?
    • Add some interesting stuffs. Such as the last part of the oscilloscope lab, but most people have no chance to do it.

12:51, 29 September 2010 (EDT)I agree that some interesting stuff is usually missed.  It takes most people a lot of time to become familiar with the oscilloscope, so it may be unavoidable.
