Established Audio Analyzer Adds 1-MHz FFTs

Delivering an impressive 24-bit resolution when measuring out-of-band noise in Class-D audio amplifiers, the BW52 option extends the APx525 family of audio analyzers’ FFT capabilities up to 1 MHz. In addition to the 24-bit resolution, the option also enables a 2.38-Hz bin width, making the analyzers desirable for looking at out-of-band noise in Class-D amplifiers, sigma-delta converters, and other current audio devices. The BW52 option is compatible with the APx520, 521, 525, and 526 analyzers and will be available in January 2010. Price is $2,500. For further information, call AUDIO PRECISION INC., Beaverton, OR.
