APx500 Flex Audio Analyzer

Across all measurements, the APx500 user interface is fast and intuitive. Just click to select a measurement, then click to add a filter. Drag limits to set pass/fail points right on the results graph. Effortlessly specify computations for derived results. Add defined measurements in a series and run them in an automated procedure called a Sequence. The APx generator can output steady tones, twin tones, sweeps, chirps, multitones, or play WAV files as arbitrary waveforms.

Repetitive bench tests and production testing can easily be automated with the built-in measurement sequencer and saved as a project that can be used with any APx analyzer. Production Test mode provides an optional simplified operator interface with multiple run statistics, created and supervised by a manufacturing engineer. Access the API if you prefer: documentation for VB.NET, C#.NET, MATLAB and LabVIEW is included.

Flexibility

APx500 Flex is compatible with ASIO-capable audio interfaces. Choose the interface product that matches your budget and your application’s performance requirements.

Configurability

APx500 Flex continues AP’s tradition of highly-configurable measurement solutions. Select measurement options based upon your test requirements, with the ability to purchase individual measurements or value-priced Flex Packs.

Portability

Software licensing for APx500 Flex is facilitated by the APx500 Flex Key. Move your measurement licenses from one computer to another simply by moving your APx500 Flex Key.

Automation

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.

Common Software Platform

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, 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.

SYSTEM PERFORMANCE

Determined by user-selected audio interface (sound card)

SYSTEM REQUIREMENTS

• Microsoft Windows 10, or Windows 8, 64-bit operating systems.

• PC with 2 GHz or faster multi-core processor (2 or more cores)
Note: the Intel Atom dual-core processor does not have sufficient performance to run APx software.

• 2 GB or more RAM (4 GB or more recommended for Windows 8).

• More detailed information is available on our AP Software and Windows Compatibility chart

NOTES

• System performance is sensitive to processor speed; faster processors will yield faster results.

• APx500 is data intensive and it is recommended that other data-intensive applications not be run concurrently. This includes Audio Precision AP2700, APWIN or ATS.
