For the impedance lab, we are doing things a bit differently from the lab manual. The manual contains three experiments: DC voltage source, AC impedance, and nonlinear elements. We are eliminating the first and last -- you should only include the AC impedance experiment in your reports. The other two parts are now optional exercises.
Below are some resources for this lab. The new instructions override the lab manual. However, the manual does contain useful information about resonant circuits and about extracting the component values with linear fits.
Instructions for performing the AC impedance experiment.

Example results for one box. The results for each box in your report should be similar. That means including: circuit diagram for your model of the box's equivalent circuit, theoretical impedance equation for the model, and plots simultaneously showing experimentally measured impedance and model impedance vs frequency (both magnitude and phase). The second figure shows the experimental setup. Like the examples, you should also include detailed captions.

Primer on AC circuits and complex impedance. The last page contains useful info about connecting your experiment to the theory.

I recommend using a more advanced plotting tool, like python, matlab, or grace, for this experiment. It's possible, but quite tricky, to do what you need to with a spreadsheet. More info and resources about plotting and analysis tools will be coming soon. Good luck!
