The APx517B Series acoustic audio analyzer is specifically designed, configured and priced to meet production-line needs. It is ideal for the testing of speakers, microphones, headphones, headsets and the wide range of consumer electronics incorporating speakers and microphones. With the APx517B, manufacturers can deploy an integrated acoustic test system that brings the renowned quality, reliability and robustness of AP’s lab-oriented analyzers to their manufacturing lines. As an integrated system combining audio analyzer (signal generation and acquisition), power amplifier, headphone amplifier and microphone power supply, along with any required digital interface such as Bluetooth, the APx517B has the power to drastically reduce setup and reconfiguration time by eliminating multiple individual components and their associated cabling.
Features
Combining audio analyzer, power amplifier, headphone amplifier, and microphone power supply, along with optional digital interfaces, the APx517B can drastically reduce setup and reconfiguration time. And as a system, the APx517B is backed by a three year warranty and is delivered with a Certificate of Traceability, confirming that each unit meets its published specification. For added reliability, the APx517B is built with overload, short circuit, and reverse current protection.
The APx517B maintains the APx Series’ tradition of flexibility and configurability. In its base configuration, APx517B is a ready-to-go system for measuring analog speakers, microphones, headphones, or headsets. For digital devices, APx517B has a module slot for the addition of a single APx digital interface module, such as Bluetooth, PDM or HDMI.
On the software side, a standard system provides a core set of measurements and functionality to allow out-of-the-box, fundamental test of acoustic devices. Additional advanced measurement options are available, either individually or in groups.
From a practical perspective, APx audio analyzers use a common software platform, making tests and results easier to share. All settings for a test are saved in a single project file, making it easy to replicate test setups between R&D and production facilities anywhere in the world. Project files are compatible with APx500 Flex, B Series or legacy APx instruments and each project is self-contained, so there’s never any worry about dependencies or broken links.
Users can even embed waveform files and images within a project file. For sharing measurement results with customers, contract manufacturers or management, APx automatically generates rich graphic reports, with highlighted pass / fail limits and options to export as PDF, HTML, Excel, CSV, RTF or MATLAB files.
Unlike any other system available, the APx517B provides specific impedance accuracy via the dual-channel Kelvin impedance measurement capability of its power amplifier and headphone amplifier.
APx500 Audio Measurement Software
Scalable, Flexible Audio Software
The APx500 Measurement Software is the most advanced audio measurement interface available. Complex procedures that include user prompts, limits, and calls to external applications can be created directly in the GUI, saving time and money while ensuring painless updates over time and no development is required. AP offers a wide range of options tailored to specific applications, including: electro-acoustic testing, perceptual audio test, and speech intelligibility.
