Electrochemical Impedance Spectroscopy

Hi everyone,

I'm a student at the University of Waterloo and I want to create a Nyquist plot. I found some videos online on how to create an electrochemical impedance spectrum using a potentiostat and I was told we can create one with a function generator and an oscilloscope. Is there a Math feature on the DSA 71604 that would allow me to measure the impedance for a range of frequencies and would I be able to save all that data in one go or would I have to set the frequency to for example 1 kHz on the function generator and then let it go through my circuit into the DSA and get the value and then manually change the frequency again?

Any help would be appreciated!

Thank you :3

The DSA 71604 oscilloscope has math functions, but to create a Nyquist plot, you'll need to manually adjust the frequency on the function generator and record impedance values. Some oscilloscopes offer automation for frequency sweeps, but it depends on your model's features.
