AP - The Recognized Standard In Audio Test

APx515HOME/PRODUCTS/APx SERIES/APx515

APx515

The APx515 is a high performance audio analyzer optimized for production test. APx515 has a typical THD+N of –106 dB, a one million point FFT with 24-bit resolution, and 192K digital I/O. It is a best-in-class instrument for its speed, performance, automation, and ease-of-use.

APx515 is a significant product because it delivers the performance and reliability of Audio Precision at a production-level price.

APx is the fastest audio analyzer in the world, returning 21 audio measurements in as fast as 1.2 seconds. It is also the easiest to use, with one-click measurements, custom reporting and sophisticated automation without any programming. A full API and LabVIEW driver is also provided.

This speed and ease-of-use means test will never be a bottleneck, and production line managers can achieve reliable, consistent results compared to the current low-cost alternatives like a distortion analyzer.

For companies outsourcing their production, requiring APx515 on the production line gives tighter control over production, ensuring manufacturers are meeting their contractual requirements.

Easy automation delivers comprehensive test in 3 seconds.

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.
