Lab 5 Feb 20/22

Goals

Improve LabVIEW and DAQ skills

Use skills from last week

Learn how to save ALL data sets with automatic file names

Begin learning about analog electronics

RC Circuits

Protoboards

In case you forget: Have Fun!

You are encouraged to wander off the path-to-be-beaten. You know how we grade. Explore and learn.

Requirements

As always,. have an excellent notebook throughout

Fork and clone github

DAQ

Last week we learned how to use the MCC DAQ cards

Three weeks ago, we learned how to save data to a file

You must frequently save data sets WITHOUT overwriting them. Some will be mistakes, etc., but just save them all. The secret to this is to have automatic filename generating code and to take good notes in your notebook. In today's world of lots of disc space (and tomorrow's world of even more), this is a good strategy

Keep in mind the maximum sampling frequency that you learned last wek

RC Circuit, High-Pass filter

Using protoboard

MCC DAQ card

Oscilloscope for debugging

Modify your buffered data acquisition VI from last week

Take data sets AND save them automatically with automatic filename generation (so files are saved, not overwritten, Good practices, Use the time and date string to create filename, Save a corresponding screenshot of front panel, Take a photo of your circuit and put in your notebook for reference, When you have a meaningful dataset, specifically link to it in your notebook (keep all of the datasets, just ignore the ones you think are garbage and / or make note that they are garbage in your notebook)

Make a plot of peak-peak voltage versus frequency

Is the cutoff frequency what you expect from RC value? (f = 1/ (2 pi RC)

Upload your final plot (voltage versus frequency), with description and link to data set to Figshare

Create an account at figshare.com

Upload figure, Author list is your name & Anthony/Steve & anyone else who helped, Tag your figure with, Electronics, 308L2012, RC Circuit, Etc.

Link to your figshare document in your lab notebook
