This is a good summary. Your future summaries will probably need to be a bit longer, to cover more results.

I used oscilloscope and write a formal lab repoet.

Lab manual:

• PDF. (Here is a stored version of his PDF)
• Online.

Notebook:

• The oscilloscope lab

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.

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.
