This 19-page technical note discusses manufacturing (or production-line) test of audio and acoustic devices.
Jan. 6, 2021
This technical note examines the automated test capabilities built into APx500 measurement software, with emphasis on capabilities specifically intended to support production-line (or manufacturing) test applications. A practical example—the manufacturing test of loudspeakers using an APx517B acoustic analyzer—is reviewed, including discussion of “golden units” (reference devices), input equalization, multiple sequences in a single project, and Production Test mode.
