New virtual instrument selects frequency filters
National Instruments has released the NI Sound and Vibration Measurement Suite 2009, a collection of the developers machine condition monitoring and audio test applications. The suite features a new continuous frequency sweep virtual instrument (VI) used to perform frequency response tests. The collection additionally utilizes an AES17-compliant audio filter VI that provides the correct frequency filters for testing audio devices that involve digital-to-analog conversion technology.
The LabVIEW VIs in the Sound and Vibration Measurment Suite contain octave analysis, frequency analysis and order tracking for automotive, military, aerospace, mechanical and structural designs. The measurement collection includes the NI Sound and Vibration Assistant 2009 -- software used to acquire, analyze and log acoustic, noise and vibration data.
The NI Sound and Vibration Measurement Suite 2009 can be purchased from the National Instruments online store for $4000.
