in SignalAnalyzer: change spectrogram settings for all displayed spectrograms

Hello,

I'm often comparing signals spectrogram within SignalAnalyzer, is there a way to change the settings (e.g. frequency limits) for all displayed spectrograms?

As far as I know, I need to do it for each of them, and do it again if I load a new signal.

Thanks

Nico

Hello @Nicolas!

I understand you are looking for a way to change the settings for all displayed spectrograms. I could not seem to find any explicit functionality to do so, however you can follow the following steps to make the process easier-

• Click Spectrogram on the Display tab to compute and display the spectrogram.
• When you have the optimal settings for your signal, click Generate Script and select Spectrogram Script to generate a script that you can use in MATLAB.
• You can then save and reuse the generated script to load and display multiple signals with consistent spectrogram parameters.

The following documentation provides helpful tips for working with the Signal Analyzer:

Hope this helps!
