What It Is
CWRU bearing vibration, normal baseline. Drive-end accelerometer at 12 kHz, ~1797 RPM, healthy ball bearing.
Interpretation
Standard analysis sees: red spectrum (low-frequency / 1-over-f power). The atlas finds no named structure, but the source is distinctively extreme on AutoRegressive:ar_coef_7 (+3.8z) — beyond what the standard bank predicts for it. It sits beside Ocean Swell in the atlas (standard-bank rank 21) — a neighbor conventional features miss.
