Reference Data Processing VIs

Installed With: Sound and Vibration Measurement Suite. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Reference Data Processing VIs to perform compensation tasks with reference data on the calculated signals.

The VIs on this palette can return general LabVIEW error codes or specific sound and vibration error codes.

Palette ObjectDescription
OAT Compensate Even Angle SignalCompensates an even-angle signal. You can use the compensated even-angle signal output to display unfiltered orbit and timebase plots with the runout pattern removed. The data type you wire to the even-angle signal input or the vector references input determines the polymorphic instance to use.
OAT Compensate Vector DataCompensates for the shaft bow and electrical variations in displacement transducer signals. This VI performs slow-roll compensation by subtracting vector references from the corresponding magnitudes [RMS] and phases [phase lag].
OAT DC Gap EstimatorComputes the averaged DC gap voltage and subtracts the gap reference. The data type you wire to the even-angle signal input determines the polymorphic instance to use.
OAT Get Even Angle ReferenceComputes the even-angle reference of the scaled signal [EU]. The output reference is the even-angle spaced signal with a constant number of samples per revolution. The data type you wire to the scaled signal [EU] input determines the polymorphic instance to use.
OAT Get Gap ReferenceComputes the gap reference of the scaled signal you acquire from a DC-coupled displacement transducer channel. You can subtract the gap reference value from a signal to calculate the actual movement that the displacement transducer measures. The data type you wire to the scaled signal [EU] input determines the polymorphic instance to use.
OAT Get Vector ReferenceComputes the vector references of the specified orders from the slow-roll vibration signals. Use the vector references to compensate shaft bow or runout errors. The data type you wire to the scaled signal [EU] input determines the polymorphic instance to use.
