Ni launched the latest upgraded sound and vibration measurement kit applied to noise spectrum analysis editor's note: Ni launched the latest upgraded sound and vibration measurement kit applied to noise spectrum analysis, Ni 2009 sound and vibration measurement kit effectively shortened the test time in noise spectrum analysis and testing

October 2009 - national instruments, Inc. (Ni) recently launched noise Applications such as vibration and acoustic vibration roughness (NVH), instrument state detection and audio testing are briefly introduced here as a complete signal analysis and processing tool - Ni 2009 sound and vibration measurement kit. The suite includes a continuous frequency scanning virtual instrument (VI), which can greatly reduce the time required for engineers and scientists to conduct frequency response tests; The new aes17 adaptive audio filter VI and Ni sound and vibration assistant that can be used in the graphical development environment of NI LabVIEW can provide the correct frequency filter for the tested audio equipment by using digital to analog conversion technology

continuous frequency scanning VI can test frequency response and total harmonic distortion, and the time used is one tenth of that of the traditional sine scanning method. This function enables engineers and scientists to easily switch between time domain and frequency domain, providing the ability to exceed the use of fast Fourier transform (FFT) in signal analysis. With the improvement of test speed, continuous frequency scanning enables users to eliminate the method: please check whether the sensor selection in the online setting is correct, and analyze the response characteristics of new signals (such as residual signals of the equipment to be tested) without excitation signal interference

in addition to the new aes17 adaptive audio filter and continuous frequency scanning VI, LabVIEW VI in Ni 2009 sound and vibration measurement kit also includes frequency doubling analysis, frequency analysis and order tracking, which are used in automotive, military, aviation, mechanical and structural design. The measurement kit also includes Ni 2009, which may be a short sound and Vibration Assistant for sample processing. It is an independent application for rapid acquisition, analysis and recording of sound, noise and vibration data. The latest version of the Ni sound and Vibration Assistant includes user interface enhancements to provide convenient setting of the flow meter and support for vortex current probes in displacement measurement. With the configuration based Ni sound and vibration assistant or more than 50 available LabVIEW sample codes in the Ni 2009 sound and Vibration Measurement Suite, engineers and scientists can develop applications quickly and efficiently
