How to draw Bode plot and Nyquist plot with the data generated by Evaluation software AD5933 EBZ ???
Please explain the process.
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.
Thank you Miguel.
Can you explain how we can plot the bode plot and nyquist plots with clear explanation ?
Moreover, Can We able to find the System transfer function of EVAL AD5933EBZ with the generated excel data ???
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?
You said that Nyquist plot requires to operate with raw data. What do you mean by raw data ?
Cant we generate nyquist plot with the help of csv file ?
I do not remember if the csv file exports the raw data (Re and Im) from the AD5933...
Could you confirm, please?
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.
Just to confirm your inquiry, the AD5933 eval software returns real and imaginary values of the DFT.
