Semi-Stationary Averaging

Hello everyone,


I would like to know how "use Semi-Stationary Averaging" in the Aquisition parameters of the Time Data Processing worksheet work. When is it useful and can I use it for fluctuating tacho signals, that means no constant tacho signal and no run up, too? 

Thank you!

You can select "Use Semi-Stationary Averaging" when tracking on Time, Tacho, Static or Event.  It allows you to do averaging at each tracking point.  I would only use it for a really slow run up or run dow, or a a stepped acquisition where you want acquisitions at each step.  The steps could be differing speeds, different loads, etc.


I would avoid it if frequencies are changing from average to average.   


Here is an example using a stepped speed:
