Low Frequency Noise – the XL2 now offers a valuable Toolbox for effective Assessment

The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data.

Easy testing of Class-D Amplifiers

Class-D (or switching) amplifiers are popular, not only because of their light weight, but mainly because they are highly efficient, with less power distributed as heat. Their audio parameters, however, can be difficult to measure because of high-frequency noise produced at the output stage. NTi Audio solves this by filtering out these unwanted noise components with the FX100 Audio Analyzer plug-in module filter, providing reliable test measurement of class-D amplifiers.

NTi Audio provides the XL2 Audio and Acoustic Analyzer as a top-class entry-level QC test solution that produces reliable results every time. This solution can equally test the sound of mechanical components such as drills, where product quality decisions are based on the frequencies of the mechanical sound produced.
