Cyclic Time Averaging with SKF @ptitude Analyst

Cyclic Time Averaging (CTA) is a post process operation that operates on time waveform signals, creating an averaged waveform similar to a Synchronous Time Averaging (STA) measurement. Unlike STA, CTA
does not require a trigger and can be computed on already acquired time domain signals. CTA is a technology that can aid in helping to identify fault sources; it is meant to complement the existing array of techniques.

SKF @ptitude Analyst implements CTA through the use of derived POINT functions as well as a visualization technique through an overlay in the time waveform graph. This article gives an explanation of the CTA process as well as a description of its use through derived POINTs and the time domain overlay.
