order tracking gen.

Вечер добрый,
помогите, пожалуйста, определиться, что такое
Order Tracking в данном контексте . Казалось, что это отслеживание последовательности, но что-то по тексту возникли сомнения. На разряды тоже не похоже

Благодарю

Rotational Dynamic Acquisition & Analysis
Providing Real-time Order Tracking

The high channel count Spider systems provide a wide range of real-time order tracking capability to understand the noise and vibration induced within rotating and reciprocating machines ....

Crystal Instruments provides post processing order tracking capability in its Post Analyzer (PA) that generates the same analysis results as real-time order tracking...

After data sampling, a flexible radix FFT converts the time/angle data into the frequency/order domain. The flexible radix algorithm provides a much broader choice of resolutions and spans than does a power-of-2 FFT for extraction of the order amplitude values as a function of RPM...
