Hello guys,
is there a way to log signals with one sample time?
I habe an system model which works with variable steps. Form 1e-3s to 50e-6s.
For the post-processing i would like to save all data to an Excel or plot data wih origins have different sample times.
At the moment my ways is to youse a rate transition block.
Is there a more elegant way?
Thanks in advance.

You can always specify the sample time of the data logging (ToWorkspace block or signal logging). Keep in mind though that this actually force the simulation steps to be changed, even when you specify variable step and variable step solver. But if you don't mind the effect, you can go ahead.
Another way is to log the data using inherited sample time and run resample() to do post data processing.

right click the signal line, properties, give it a name, check "log signal data" and specify the sample time
