Order analysis and tracking techniques are essential in measurements with varying rotating speeds. Getting correct results from run-up/down requires specific signal processing techniques.
Synchronous Order Analysis (SOA)
Provides stable and repeatable measurements for any speed-varying machinery. Using proven real-time angular resampling algorithms, SOA extracts amplitude and phase of orders; even from fast transients.
Waterfall & Profiles
This specific plug-in collects and synchronizes all data coming from the analyzers data stack. Results are sorted based on a choice of references for the Z Axis (RPM, time and levels) and represented in 3D or profile views (Bode plots, cross-phase tracking, ...). Identifying the critical analysis item, such as speed, is then much easier as its effects are seen in different dimensions: order, frequency, octave. The section manager of the waterfall plug-in feature orders, overall, constant frequencies and spectra extraction in one click.
Constant Band Tracking
Helps the user acquire gearboxes’ modulated and often buried noise and vibration orders
