Dear Friends,

How to draw Bode plot and Nyquist plot with the data generated by Evaluation software AD5933 EBZ ???

Please explain the process.

Dear Friends,

Hi Nikhil,

The Bode plot is generated straight forward downloading impedance data.

The frequency, impedance and phase are each one in a different column.

For the Nyquist plot... requires to operate with the raw data, and this is not exported (as far as I remember) to the csv file...

What do you mean with AD5933 transfer function?

Miguel

Hi miguel,

From the data sheet of AD5933EBZ we can calculate the real and imaginary impedances.

If you can go through this document http://www.analog.com/static/imported-files/eval_boards/537700023EVAL_AD5933EB.pdf

You can find the formulae to find real and imaginary magnitude of impedance in page no. 28 namely Zreal and Zimg.

Hi Nikhil,

The bode plot should be relatively simple using the plot function in excel or libreoffice.

For the nyquist plot you require real and imaginary... which means that you need to operate with the raw data... Im writing an AN to described how to generate impedance and reactance from AD5933 results.
