Oscilloscope Lab Summary
In this lab, I learned how to use an oscilloscope and gather useful data from it. The main overview of the lab is provided in the Lab Manual, and my procedures and other relevant data are provided in my lab notebook:
Main Data
- Fall Time= 51.20ms (cursor)
- Fall Time= 48.24ms (measured)
The first number, as noted, was obtained by using the cursor measurements. Because of the discrepancy between my cursor measurement and the oscilloscope built in measurement, I think a reasonable uncertainty is ±3ms. The time that I decided to use in calculating the time constant, τ, was my cursor measurement:
- Vf=Vo·exp(-t/τ), Vf/Vo=0.1, t=48.24ms
- τ=22.24ms
Conclusions
- In this lab, I learned how to use the oscilloscope. I learned how to use triggering, how to manipulate the wave, how to make useful measurements and how to operate the device in general. I am sure that this is a useful skill which I will continue to develop throughout the coming weeks and semesters. Unfortunately I didn't quite understand what exactly AC and DC coupling did (although Dr. Koch showed me what AC coupling was useful for). However, I am sure that this will become more clear as the semester progresses.
- I definitely didn't go outside of the standard procedure as much as I would have liked. Although I did get to try out many of the oscilloscope's functions, there are many more that I was unable to test out due to the time constraint. In fact, I never even got to the FFT section, or to the 'Other' section that came after.
- To make the lab better, it might be a good idea to get students to get started on it the very first day of lab so that they have more time to mess around with the device.
