Course Overview
Advanced Spectrum Analysis & Full Fault Diagnostics
Category II takes you from recognizing vibration patterns to confidently diagnosing complex faults on rotating machinery. This is the course for analysts who need to write formal diagnostic reports, recommend corrective actions, and defend their findings to engineering and management teams.
Real case studies from industrial facilities are used throughout. By day three, participants are performing live analyses on seeded-fault machines.
Curriculum
Review of Cat I fundamentals and common failure modes
Advanced FFT analysis — window functions, aliasing, leakage
Detailed bearing defect frequency analysis (BPFO, BPFI, BSF, FTF)
Envelope analysis / demodulation for early bearing fault detection
Gear mesh frequency and sideband analysis
Resonance and critical speed identification
Structural looseness — rotating vs. structural differentiation
Soft-foot diagnosis and correction verification
Rub, oil whirl, and oil whip in journal bearing machines
Cepstrum analysis for gearbox and bearing diagnostics
Advanced time waveform interpretation
Bump testing and natural frequency identification
Formal diagnostic report writing and severity ratings
CMVA Cat II exam preparation and practice examinations
Prerequisites
Participants should hold CMVA Category I certification or equivalent practical experience (minimum 3 months vibration data collection). Contact us if you are unsure whether you are ready for Cat II.
