Audio Precision APX515B Audio Analyzer
The Audio Precision APx515B Series stands out as a premier audio analyzer meticulously designed for production testing. Renowned for its unparalleled combination of speed, precision, and user-friendly automation, the APx515B sets a new standard in the industry. With the ability to perform key audio measurements in under three seconds, it offers remarkable efficiency without compromising on performance.
This high-performance analyzer delivers a typical Total Harmonic Distortion plus Noise (THD+N) of –106 dB, backed by advanced 1.2M point FFT processing and exceptional digital I/O capabilities of up to 216k. The intuitive one-click automation feature enhances usability, ensuring that audio testing is both straightforward and efficient.
Operating in either stand-alone mode or under the control of a master .NET or LabVIEW application, the APx515B provides versatile testing solutions. Users have the flexibility of controlling the unit via a keyboard, foot switch, or barcode scanner, with full automation options available for streamlined testing processes. The system easily supports external devices and switchers, including pass/fail lights, allowing for a comprehensive production line setup.
In its stand-alone mode, users can craft sophisticated test sequences by simply selecting from a pre-defined list of common audio measurements—no coding skills are necessary. When integrated with a master application, users can access a robust API or utilize the APx LabVIEW driver for seamless operation. The system is adept at making individual measurements or executing comprehensive test sequences developed through the user interface.
