AP - The Recognized Standard In Audio Test

The APx515 is a high performance audio analyzer optimized for production test. It is a best-in-class instrument for its speed, performance, automation, and ease-of-use.

APx515 can make all of the key audio measurements in less than three seconds. Despite its low cost, APx515 still has excellent performance, with a typical THD+N of –106, 24-bit FFTs, and 192K digital I/O as well as the one-click automation and ease-of-use of all APx Series audio analyzers. Like all AP instruments, APx515 comes with an ISO:17025 Accredited Calibration and three year warranty, so its results are trusted everywhere.

Comprehensive test in 3 seconds, easy automation AND
low cost. Starting at $6200 in the US.

APx515 operates either as a stand-alone test unit with its own user interface or it can be controlled by a master .NET or LabVIEW application. In either case, an operator can control APx with a keyboard, foot controller or barcode scanner, or the system can be totally automated. Switchers and external devices such as pass/fail lights are also supported.

In stand-alone mode, sophisticated test sequences are created by selecting from a list of common audio measurements—no coding required. Pass/fail limits, advanced configurations and user prompts can be added as necessary, then the type of report is selected—rich graphic prints using Microsoft Word or export to CSV. The project can be locked to prevent accidental changes once on the production line.

On an automated line, the master .NET or LabVIEW application can control the APx515 directly using the API or APx LabVIEW driver. Individual measurements can be made or the master application can call a test sequence created with the APx UI.
