Affordable Analog + Digital Audio Testing for the Extended R&D Team
The APx516B is a two-channel audio analyzer with an optional module slot. It combines analog and digital audio testing at a price point previously unavailable in the market. Using an Audio Precision analyzer ensures consistency across the entire product development process, especially for extended, distributed, and remote teams, eliminating the discrepancies often seen with makeshift or ad hoc approaches. Key features include:
- 2 Analog Signal Generator Channels
- 2 Analog Signal Analyzer Channels
- Optional module slot for all current and future APx500 digital audio interface modules
Streamlined Production Testing and Automation
The APx516B streamlines production testing with an instrument that seamlessly integrates both digital and analog audio connectivity. Directly compare data between R&D and manufacturing, make all key audio measurements in less than three seconds, and automate testing with a well-documented Application Programming Interface (API). Key features include:
- Automation support through .Net, Python, Labview, Matlab, and more
- Robust hardware suitable for 24/7 operation on a manufacturing line
- 3-year standard warranty, or 5-year extended warranty
- Accredited, ISO 17025 calibration from the factory
Power Line Error Simulation
The APx555 supports the complete range of APx digital I/O options, ensuring compatibility with a wide array of audio formats and devices.
