Uninstalling Previous Versions
Redistributing Executable Sound and Vibration Applications
The NI Sound and Vibration Toolkit includes a collection of VIs that you can use to perform typical measurements for audio, acoustic, or vibration applications. The Sound and Vibration Toolkit also includes the NI Sound and Vibration Assistant. The NI Sound and Vibration Measurement Suite provides order analysis functionality for the Sound and Vibration Assistant and LabVIEW in addition to the Sound and Vibration Toolkit. The Sound and Vibration Measurement Suite also provides additional functionality in LabVIEW such as human vibration filters, torsional vibration measurement VIs, and custom displays.
Use the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite to perform the following sound and vibration measurements:
The Sound and Vibration Measurement Suite includes the following new features in LabVIEW.
Torsional vibration is a common phenomenon for rotating machinery such as engines, compressors, and turbines. High torsional vibration in a rotating system can cause the failure of rotating components or damage to the system. Use the Torsional Vibration Measurement VIs to measure and monitor torsional vibration in rotating systems. The Torsional Vibration Measurement VIs can calculate torsional vibration signals from both analog and digital tachometer signals. The Torsional Vibration Measurement VIs also can compensate for geometric imperfections that a tachometer system might have.
Human vibration refers to the effects of mechanical vibration on the human body. Measuring and analyzing human vibration signals can help control the negative effects of mechanical vibration on the human body. Use the SVT Human Vibration Weighting Filter (Fixed Rate) VI, the SVT Human Vibration Weighting Filter (frequency) VI, and the SVT Human Vibration Weighting Filter (octave) VI to apply weighting to human vibration signals in both the time and frequency domains. Applying weighting to human vibration signals can isolate the directional components that you are interested in and help you further analyze different types of human vibration.
The Sound and Vibration Measurement Suite now supports order analysis functionality on VxWorks Real-Time targets.
To run the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite, your computer must meet the following minimum system requirements:
You must uninstall previous versions of the Sound and Vibration Toolkit, the Sound and Vibration Measurement Suite, and the Order Analysis Toolkit before installing the Sound and Vibration Toolkit 6.0 or the Sound and Vibration Measurement Suite 6.0.
Complete the following steps to uninstall previous versions of the Sound and Vibration Toolkit, the Sound and Vibration Measurement Suite, or the Order Analysis Toolkit.
You must be logged in with administrator privileges to install the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite. Note the following considerations when installing these products.
Complete the following steps to install the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite:
You must restart the computer after you install the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite.
If you install the Sound and Vibration Toolkit 6.0 or the Sound and Vibration Measurement Suite 6.0 in LabVIEW 8.5 or later, you must mass compile the following directories to improve the loading speed of the Sound and Vibration VIs.
If you mass compile these directories but do not have NI-DAQmx installed, the Sound and Vibration VIs that use NI-DAQmx are broken.
Refer to the Known Issues section of this document for installation known issues.
If you want to redistribute executables built with the Sound and Vibration Measurement Suite or any of its components, you must purchase the appropriate NI Sound and Vibration Software Run-Time License. The part number for the NI Sound and Vibration Software Run-Time License is 779875-01. Contact National Instruments to purchase the NI Sound and Vibration Software Run-Time License.
The version of LabVIEW in which you install the Sound and Vibration Toolkit 6.0 or the Sound and Vibration Measurement Suite 6.0 determines the way in which you can access the help.
Refer to the LabVIEW Help, accessible by selecting Help»Search the LabVIEW Help in LabVIEW, for information about the Sound and Vibration VIs.
Select Help»Sound and Vibration Measurement Suite Help in LabVIEW for information about the Sound and Vibration VIs.
Note: The Sound and Vibration Concepts book contains the contents of the LabVIEW Sound and Vibration Analysis User Manual that ships with the Sound and Vibration Toolkit 5.0 and the Sound and Vibration Measurement Suite 5.0. The Sound and Vibration Toolkit 6.0 and the Sound and Vibration Measurement Suite 6.0 no longer provide the LabVIEW Sound and Vibration Analysis User Manual.
You can find LabVIEW examples for the Sound and Vibration VIs using the NI Example Finder. Select Help»Find Examples to launch the NI Example Finder. You also can click the Find Examples link in the Getting Started window to launch the NI Example Finder.
Use the Browse or Search page of the NI Example Finder to find an example VI. On the Browse page, the Sound and Vibration example VIs are located in the Toolkits and Modules»Sound and Vibration folder.
The following list describes known issues at the time of release. Refer to the Knowledge Base at ni.com for the most recent information about known issues.
The following items are the IDs and titles of a subset of issues fixed in the Sound and Vibration Toolkit 6.0 and Sound and Vibration Measurement Suite 6.0. If you have a CAR ID, you can search this list to validate that the issue has been fixed. This is not an exhaustive list of issues fixed in the current version of the Sound and Vibration Toolkit and the Sound and Vibration Measurement Suite.
| Bug ID | Fixed Issue |
|---|---|
| 46JFUHW9 4579QD00 | Zoom FFT VIs do not coerce number of lines. These VIs now support zoom frequency resolutions finer or coarser than the baseband frequency resolution. |
| 4ADCS1W9 | Zoom Power Spectrum Express VI exports frequency range and number of lines as controls that can be input to the Express VI at run time. |
| 4BUMFR3R | Code generation for multichannel Tone Measurement Express VI was modified to perform tone measurements on all channels. |
| 3ZOCOQW9 | SVT SNR without Harmonics VI uses a more robust algorithm that is less susceptible to underestimation of the level of the noise in the presence of high harmonic energy. |
| 4DBEARW9 | Getting Started with SVT example does not return error if example stopped before Playing WAV file because the sound task is only cleared if it is created. |
| 4APF9UW9 | Examples for DAQmx measurement devices support AC coupling and IEPE excitation through front panel controls, a popup dialog, or by setting a block diagram constant. |
| 4AD7IW9 | SVXMPL_Continuous Broadband Waveform VI and SVXMPL_Generate Excitation VI are executable because both VIs now call supported subVIs. |
| 497CM8W9 | UFF Write Express VI writes converted unit string to Record 9 when dB spectrum converted to linear spectrum. |
| 4D4CS4K9 | UFF Plugin version 2.2 writes correct number of bytes in the file header for all supported datatypes for both single- and double-precision writes. |
| 4BFCKEUCK 46LEHQYV | Sound and Vibration Toolkit and SignalExpress 2.5.1 can be installed to two different versions of LabVIEW on the same target machine. |
| 4DRCCVF3 | Support added for PXI-4498 and PXI-4496 in OAT Build Digital Tacho Info VI. |
| 3NDFI1YG | OAT Convert to Even Angle Signal VI and other continuous processing VIs now automatically reset if the input signal is not continuously sampled. |
