Owning Palette: Order Analysis VIs

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 order analysis error codes.

Palette Object Description
OAT Compensate Even Angle Signal Compensates 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. Wire data to the even-angle signal input to determine the polymorphic instance to use or manually select the instance.
OAT Compensate Vector Data Compensates 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] . Wire data to the magnitudes [RMS] and phases [phase lag] inputs to determine the polymorphic instance to use or manually select the instance.
OAT DC Gap Estimator Subtracts the gap reference from the averaged DC gap voltage of the even-angle signal and returns the DC gap in the selected units. The DC gap is a measurement of the movement of the shaft from the reference position to the current position. If gap reference [V] is unwired, the VI computes the actual gap ref [V] from the input signal. Wire data to the even-angle signal input to determine the polymorphic instance to use or manually select the instance.
OAT Get Even Angle Reference Computes 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. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.
OAT Get Gap Reference Computes 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. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.
OAT Get Vector Reference Computes the vector references of the specified orders from the slow-roll vibration signals. Use the vector references to compensate shaft bow or runout errors. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.
