Scaling & Calibration VIs

Owning Palette: Sound and Vibration 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 Scaling & Calibration VIs to scale an input signal measured in volts to the appropriate engineering units. You also use these VIs to calibrate microphones, accelerometers, or other sensors and to measure propagation delay with DAQmx or Traditional DAQ devices.

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

Refer to the examples\Sound and Vibration directory for an example of using the Scaling VI.

Palette ObjectDescription
SVL Get dB ReferenceReturns the dB reference stored in the waveform attributes of the scaled signal input. The dB reference is set by the DAQ Assistant for Sound Pressure and Acceleration tasks, the SVL Scale Voltage to EU VI, and the SVL Set dB Reference VI. The dB reference is used for all downstream conversions to dB.
SVL Scale Voltage to EUScales signal [V] from volts to the engineering units (EU) you select. The data types you wire to the signal [V] and channel info inputs determine the polymorphic instance to use.
SVL Set dB ReferenceSets the specified dB reference [EU] as an attribute in the scaled signal out [EU] waveform. dB reference [EU] is used for all downstream conversions to dB.


SubpaletteDescription
Calibration (DAQmx) VIsUse the Calibration (DAQmx) VIs to calibrate microphones, accelerometers, or other sensors and to measure propagation delay with DAQmx devices.
Calibration (Traditional DAQ) VIsUse the Calibration (Traditional DAQ) VIs to calibrate microphones, accelerometers, or other sensors and to measure propagation delay with Traditional DAQ devices.
