Fault patterns
Select a pattern to inspect its components in the spectrum.
Scorecard
Margin below the fundamental against guideline limits — longer bars are healthier.
Data quality
Drag to zoom, double-click to reset. Choose a cursor, then click the spectrum.
Around the fundamental
Pole-pass (2sf) and running-speed sidebands.
Components
The envelope spectrum shows modulation frequencies directly: pole-pass, running speed and bearing defect rates.
Envelope waveform
Stable horizontal lines indicate steady components; drifting or pulsing lines reveal load changes, speed variation and intermittent faults.
Detected families
Every peak is assigned to at most one family, so each family is a distinct source.
Park vector
A healthy, balanced machine traces a thin circle; ellipses and thickening indicate unbalance and modulation.
