Fast Setup & Reconfiguration

As an integrated system combining audio analyzer (signal generation and acquisition), power amplifier, headphone amplifier, and microphone power supplies, 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 (from a variety of vendors) and their associated cabling.

Additionally, and unlike those individual components, the APx517B is uniquely delivered with a Certificate of Traceability, confirming that each unit meets its published specification.

Designed and built for the production line

The robust hardware of the APx517B is complemented by the APx500 audio measurement software. For the manufacturing environment, 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.

APxDigital Options

APx B Series audio analyzers offer world-class performance and flexibility. Our modular systems allow you to select the interfaces and options that make sense for the work you do, covering the widest range of digital I/O in the industry. Select models support jitter generation and analysis when installed in AMCconfigured APx analyzers.

Bluetooth® – supports A2DP, AVRCP, HFP and HSP profiles
PDM – one-bit audio generation & analysis (including PSRR and jitter*)
PDM 16 – Simultaneous 16-channel PDM signal acquisition
Digital Serial – I2S, TDM, multi-line support (including jitter*)
Advanced Digital – AES/SPDIF/Optical (including jitter*)
HDMI+ARC – source, sink & monitor (including metadata)

*Advance Master Clock is standard on the APx555, and supports all jitter capable digital interface modules
Picture below shows B Series APx platform incorporates a modular architecture enabling configuration for a variety of digital I/O options.
