Test Increasingly Complex Sets of Audio Devices

​With the growing popularity of Internet of Things devices worldwide, many electrical products are adopting voice commands as their user interface. This means that acoustic and audio test challenges are likely to impact more products than ever before. Test teams must meet extended test coverage requirements to ensure product quality while maintaining throughput and operational efficiency. For a solution to meet these sorts of demands, it must:

 

  • Provide complete coverage for current and future test requirements
  • Operate within the expected cycle-time limit
  • Design, develop, and deploy within a production schedule
  • Fit into manufacturing processes both physically and operationally

NI's Audio and Acoustic Functional Test Solution

  • Reduce engineering effort and risk with a benchmarked system-level design guide
  • Efficiently test digital microphones with parallel FPGA-based PDM demodulation for high-channel-count, multiup test with 120 dB stopband attenuation
  • Utilize TestStand and LabVIEW software to rapidly develop complex test steps and sequences
  • Maximize yield with data analytics and systems-management  configurations using SystemLink™ software 

Solution Advantages

  • Confidently meet stringent test coverage specifications with high accuracy hardware

  • Insulate station investment from specification changes by updating test steps with DUT specific parameters in software

  • Increase throughput with fast measurement speed and built-in parallel testing

  • Free up budget with a lower cost per channel

“We consider NI DAQ hardware the industry standard for production test applications. The close integration with NI software ensures ready access to our coverage requirements.”

—Christian Wolf, Global Manufacturing Test Manager, GN Audio
