Continous Sweep THD VI Takes Too Long to Execute When Max Harmonic is HighContinuous Sweep THD VI takes too long to execute when max harmonic is high. Workaround: 1. Sample faster. 2. Break the sweep into two segments (high and low frequency) and decrease the maximum harmonic for the high frequency sweep. 3. Parse the acquired waveform and perform explicit resampling to angular domain (see Continuous Sweep* (Advanced) example VI). Explicitly maintain multiple resampled signals (each with appropriate sampling for the frequency resolution). |

Opening Any SVT Executable on a Target Computer Causes ErrorsWhen you open an executable that includes SoundVib_MCM Examples.lvlib on a target computer, the executable errors out due to a missing dependency, LVASPT_TFA.dll. Workaround: In Application Properties, in the Source Files category, add LVASPT_TFA.dll to your application as Always Included in the build configuration, as shown below. The LVASPT_TFA.dll file is located in the C:\Program Files (x86)\National Instruments\LabVIEW 20xx\resource\ folder. |

"File Not Found Error" Occurs When the SVFA API Is Used with AppbuilderSome of the Sound and Vibration Toolkit Frequency Analysis (SVFA) VIs cause Application Builder to fail generating an application. Note that you can still use Application Builder with SVT (Sound and Vibration Toolkit) to build applications that do not use SVFA.
This issue occurs with SVT decoupled versions on LabVIEW 2022 and LabVIEW 2023. Application Builder fails with the following message:
Workaround: To build applications with SVFA, copy the Spectrum Averaging folder from

SVT Shock Response Spectrum Is Not Working As ExpectedIn the SVT Shock Response Spectrum (SRS) function, Absolute Acceleration (the default value), works correctly but Relative Displacement does not work as expected. In the image below, relative displacement is expected to decrease with an increase in frequency. DIAdem (left side) shows the correct result, but the SVT SRS (right side) displays an incorrect result for relative displacement. Workaround: There is currently no known workaround for this issue. |

Sound and Vibration Toolkit sample projects with channels do open from the LabVIEW getting started wizardSVT sample projects with channels do not instantiate from the getting started wizard and throw file permission errors. Go to C:\Program Files\NI\LVAddons and find nisvt Right-click on the nisvt folder and remove the read-only flag Run LabVIEW in Administrator mode and then try to instantiate the sample project from getting started wizard. image Whether running LabVIEW in normal user mode or as an administrator, the error was observed with the following sample projects (which all use channel wires): Dynamic Signal Analyzer Dynamic Signal Generator 1/3 Octave Analyzer Workaround: There is currently no known workaround for this issue. |
