Owning Palette: Scaling & Calibration 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 Calibration (DAQmx) VIs to calibrate microphones, accelerometers, or other sensors and to measure propagation delay with DAQmx devices.
The VIs on this palette can return ranges of LabVIEW error codes or specific sound and vibration error codes.
Calibration measurements are normally taken with a dedicated calibrator, usually a pistonphone for microphones or a hand-held shaker for accelerometers. The Calibration VIs use the characteristics of the calibrator, such as reference calibration value and frequency, to perform the calibration. The Calibration VIs return the calibrated sensor sensitivity and store it in calibrated channel info for use by the SVL Scale Voltage to EU VI.
| Palette Object | Description |
|---|---|
| SVL Calibrate Accelerometer (DAQmx) | Performs an end-to-end calibration on the selected channel by measuring the actual sensitivity of the sensor connected to the channel and returns the measured sensor sensitivity. |
| SVL Calibrate Microphone (DAQmx) | Performs an end-to-end calibration on the selected channel by measuring the actual sensitivity of the sensor connected to the channel and returns the measured sensor sensitivity. |
| SVL Calibrate Sensor (DAQmx) | Performs an end-to-end calibration on the selected channel by measuring the actual sensitivity of the sensor connected to the channel and returns the measured sensor sensitivity. |
| SVL Measure Propagation Delay (DAQmx) | Measures the propagation delay of the measurement hardware and the device under test (DUT). You can measure the propagation delay of the device under test by subtracting the propagation delay of the measurement system without the DUT from the measured propagation delay of the entire system, including the DUT. The propagation delay is returned in number of samples. This VI uses the NI-DAQmx driver. |
