IEC60118-7 / ANSI S3.22 function library
APx511 supports a .NET library of functions that automate the tests described in IEC60118- 7 and ANSI S3.22. For the production environment, these functions can be called from any .NET capable language (including LabVIEW) to control the APx511’s output and measurement settings.
For troubleshooting or test setup, the APx511 can be controlled by the standard APx500 software providing a rich graphical user interface and access to automated reporting, real-time signal monitors, high resolution FFTs and controls for limits & other settings.
In addition to standard audio tests such as level, distortion, frequency response, and attack & release, APx511 can measure battery current using its built-in battery simulator circuit.
Built-in support for test chamber speaker, telecoil & microphone
The APx511 generator includes an in-line 4 watt loudspeaker amplifier (8 ohms) and a telecoil amplifier, allowing >110 dB SPL and up to 400 mA/m field strength from 100 Hz to 10 kHz in a test chamber such as the Interacoustics TBS25. On the input side, APx511 supplies 24 V DC of constant current through a single BNC for a pre-polarized measurement microphone.
Code-Free Automation and a Complete API
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, as no development is required.
Create custom interfaces and application-to-application automation using the comprehensive APx API. Extensive documentation and examples are provided for Visual Basic.NET, C#, MATLAB, LabVIEW, and Python. Projects and automation can be shared with other APx units anywhere in the world.
