Order Analysis 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 Order Analysis VIs to calculate and analyze order-related results such as spectral maps, order spectra, order magnitudes and phases, and order waveforms.

Note  Besides the VIs and subpalettes listed in the tables below, this palette also includes the Spectral Map Express VI, Order Spectrum Express VI, Order Tracking Express VI, Order Waveform Express VI, and Extended Measurements VIs.

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

Palette ObjectDescription
OAT Convert to Even Angle SignalConverts an even-time-spaced scaled signal to an even-angle-spaced signal by resampling the acquired signal. The output signal is synchronous to the rotational speed 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 Extract Most Significant Order WaveformsExtracts the order waveforms with the highest power.
OAT Extract Order WaveformsExtracts order waveforms from specified orders in the scaled signal [EU]. This VI can return order waveforms of a single order or combined orders.
OAT Order Magnitude and PhaseComputes the magnitudes and phases of designated orders in an even-angle signal. The data type you wire to the even-angle signal input or the order waveforms [EU] input determines the polymorphic instance to use.
OAT Order Power SpectrumComputes the order power spectrum of an even-angle signal. The data type you wire to the even-angle signal input determines the polymorphic instance to use.
OAT Overall Level PlotComputes the root-mean-square (RMS) level of the even-angle signal and generates an XY graph as the output. The data type you wire to the even-angle signal input determines the polymorphic instance to use.
OAT Spectral MapComputes a spectral map of the scaled signal [EU] as a function of time or rotational speed. This VI can return the spectral map as a 2D numeric array, a colormap, or a waterfall graph.
OAT Tachless Speed Profile GeneratorGenerates a speed profile from a sound or vibration signal without a tachometer signal.


SubpaletteDescription
Reference Data Processing VIsUse the Reference Data Processing VIs to perform compensation tasks with reference data on the calculated signals.
Utility VIsUse the Utility VIs to manipulate calculated data to obtain specific data formats or to set triggers on input signals.
