Powergui FFT Analysis Tool doesn't work!

When I use the Powergui FFT Analysis Tool (in the matlab 2019a), I find it can'work. In the module of "Available signals","Name" and "Input" are always "Empty", though I have selected “Log data to workspace” and "structure with time".Are there any other parameters to set?

[Haritha]

You are not logging the data into workspace see the image what you have attached. Name and input is empty.

[heng Zhang]

I had logged the data into workspace, but it didn't work.

[Tanya Gachovska]

I thied but, it did not work

[Zhengjin Wang]

I met the same trouble as yours! I found in old vesion things are not so complex. What they did in upgrade?

btw, are you also a student doing a physical experiment?

[Zhengjin Wang]

I find a way to solve this! You have to click the button I circled and it will display these options. Cancel the single simulation output and you can get your data after run!

[heng Zhang]

非常感谢，方法很有用。但是我不是物理实验的，而是做电力电子实验的时候用到它的。

[Vasantha Kumar]

This worked!! 100%

Thanking you. I wasted four hours and later saw your thread and the problem solved in four seconds.

[Sabir OUCHEN]

thank you a lot

[Mahdi Saberi]

Thank you very much man.

[Fredrik Svanholm]

This worked! Thanks (Matlab 2020 user )

[Gilian Dantier]

thank you a lot this worked

[Mohammad Alwardat]

thank you very much sir

[Abhishek Kumar]

Its working 100%. Thanks a lot.

[Vaibhav Hebbal]

Thank you

[Hamza Ehsan]

i am using matlab2019b and i am tired of changing discrete value of powergui but FFT analysis since showing empty results. I have also changed Configuration Parameters in "Data Import/Export" Section, the option "Single simulation output" to unselected but nothing showing. Your help will be appericiated.

thank u man, u made my day

[Mughaizi Manan]

Thank u my brother.. genius man

Thank you very much

Answer 2

[Tin Truong Chanh]

Try this: it works with my case:

1. Go to model Configuration Parameter and select Data Import/Export pane on the left
2. Untick the Single simulation output and click on Apply

[Victor Taramuel]

YOu really saved my live, thank from Ecuador

[Hasan Hamed]

Thank you ... its ok

[Ali Saj]

This Worked for me, too.

[Ali Salmani]

Thank you very much❤

[JOSHUA]

thank you soo much

[Finn]

thank you! it works

Answer 3

[Haritha]

Try this methods

1.Try to log the data into workspace otherwise.

2.This FFT window will work only after the successfull running of your model

3. Close the simulink model once and run it again

[Javed Ahmad]

I tried whatever you are saying but still it is not working for matlab 2020
