Acoustic Production Test Redefined

The APx517B Acoustic Analyzer

Introducing an integrated acoustic test system, complete with audio analyzer, power amplifier, headphone amplifier, and microphone power supply, along with an array of digital interface options.

Built for Production Test

From headphones and headsets to speakers (passive, active, or smart), manufacturing test presents its own set of unique demands for a test system. Functionally speaking, a traditional test system would be comprised of several individual components—from different vendors—include a sound card for signal generation and acquisition, a microphone power supply, an amplifier (power or headphone), and possibly a digital interface (e.g., Bluetooth®). The production test engineer has the complex job to source these components on a very limited budget, configure and calibrate them to function as single test system, and troubleshoot any individual component issues to ensure the production line stays “up.”

Fast Setup & Reconfiguration

On a production line, any time spent setting up a new test system, calibrating a system for a new shift, or reconfiguring a system for a change in DUT (device under test), is effectively a “line down” situation. The APx517B has the power to drastically reduce setup and reconfiguration time by eliminating multiple individual components (from a variety of vendors) and their associated cabling.

Quality & Reliability

Most, if not all, current acoustic analysis systems are an assortment of individual components from different vendors. As such, an additional “line down” risk of these systems is the quality and reliability of each component, along with the configuration of each connection point. In contrast, the APx517B is an integrated system engineered and assembled to the same standard as all other APx analyzers and is delivered with a three-year warranty and accredited calibration. For 36 years, the equal to AP analyzers’ reputation for performance and measurement accuracy is the long-standing recognition of their quality and reliability.

APx517B or APx500 Flex?

Depending upon your manufacturing program, along with the types of acoustic devices you’re testing, there are two primary APx solutions from which to choose: APx517B and APx500 Flex.

The APx517B is an all-in-one system, complete with an audio analyzer, power amplifier, headphone amplifier, and microphone power supply, along with the ability to add an optional digital interface. If testing digital devices—for example Bluetooth headphones or an HDMI soundbar—then the digital module capability of the APx517B will be key. Also, for a production line that sees a range of different devices, the incredibly fast setup or reconfiguration capability of the APx517B should be of great benefit.

For manufacturing lines that are more cost-sensitive and/or limited to producing analog-only devices, the APx500 Flex audio analyzer is the better choice. Comprised of APx500 measurement software—enabled via an APx500 Flex Key—paired with an ASIO-capable audio interface, APx500 Flex delivers the power and versatility of APx audio measurement software to your production line.
