Tachometer Processing VIs
Owning Palette: Sound and Vibration VIs
Use the Tachometer Processing VIs to process analog and digital tachometer signals.
The VIs on this palette can return general LabVIEW error codes or specific sound and vibration error codes.
| Palette Object | Description |
|---|---|
| OAT Analog Tacho Process | Locates tachometer pulse positions in analog tachometer signals using the number of generated pulses per revolution, the pulse width, and the arrival edge of the tachometer pulse. This VI also calculates the rotational speed of the device. Wire data to the analog tacho signal input to determine the polymorphic instance to use or manually select the instance. |
| OAT Build Digital Tacho Info | Builds a digital tachometer signal information cluster that compensates for the input filter delay in the sound or vibration acquisition channel. You can use the output of this VI as an input for the OAT Digital Tacho Process VI. |
| OAT Convert Speed Waveform to Speed Profile | Use this VI to convert a saved history of speed data sampled at regular time intervals to a speed profile suitable for order analysis with the Sound and Vibration Measurement Suite VIs. |
| OAT Convert Speed Waveform to XY Graph | Converts a waveform speed profile to an XY graph by extracting the information attached to the waveform speed profile. |
| OAT Convert Speed XY Graph to Waveform | Converts a speed profile XY graph to a waveform. This VI also attaches the information of the input speed profile XY graph and pulse-per-revolution to the output waveform. |
| OAT Detrend Analog Tacho Signal | Removes trend from an analog tachometer signal. You can use the output of this VI as an input for the OAT Analog Tacho Process VI. Wire data to the analog tacho signal input to determine the polymorphic instance to use or manually select the instance. |
| OAT Digital Tacho Process | Locates tachometer pulse positions in the digital tachometer signal and calculates the rotational speed of a device. Wire data to the digital tacho info input to determine the polymorphic instance to use or manually select the instance. |
| OAT Output Buffered Data | Buffers the input signals and returns them in first-in first-out (FIFO) mode. Use buffer settings to set the buffer size and units. Each instance of this VI maintains its own state; use the N Waveforms instance of this VI to process an array of channels. Wire data to the XY signal input to determine the polymorphic instance to use or manually select the instance. |
