Application-oriented Dynamic Signal Acquisition Modules for New Generation Audio and Vibration Measurement
Based on various bus standards, ADLINK’s Dynamic Signal Acquisition (DSA) modules are specifically designed for audio, noise, and vibration measurement applications. Featuring up to 432 kS/s sampling rates, 24-bit resolution, and IEPE signal conditioning, the series delivers highly accurate signal acquisition and easy connection to microphone or acceleration sensor for component testing. ADLINK further provides a wealth of industrial-grade computer and PXI platforms enabling customers to choose the products most suitable to their own audio and vibration applications, speeding system development.
Audio Testing Solution Comparison
| Advantage | Disadvantage | |
| Audio Analyzer | • Sound analysis system based on industry references • Complete analysis software • Support digital audio testing | • Bulky and occupy space • Expensive and unsuitable for the production line applications • Time-consuming and longer maintenance and verification cycle time |
| ADLINK Solution BEST SOLUTION! ADLINK | • PC-based architecture to easily integrate with other test functions and quickly complete automated testing system in production lines • 24-bit high resolution, low distortion and low noise specifications offer more precise measurements to meet high-end audio product testing standards • Complete sound vibration testing applications through integrating with IEPE to directly connect microphone or acceleration sensor • Synchronous trigger of Al and AO to enhance stability and consistency of audio loop testing • Significantly reduce testing costs but better test performance quality | • The lack of complete analysis software, particularly as compared to traditional audio analyzer • No digital audio testing support |
| Sound Card | • Low Price | • Poor accuracy and design quality are prone to high false detection rate and maintenance rate • Obtaining imprecise testing results through Lower distortion and noise specifications is unable to meet high end audio product testing needs • The different time differences lead to inconsistent and unstable test results when triggering analog inputs and analog outputs simultaneously |
Superior Performance for a Variety of Audio Testing Needs
With the evolution of electronic multimedia devices, manufacturers must take advantage of not only electro-acoustic technology and system design expertise, but also complete audio testing systems to ensure product quality. ADLINK’s dynamic signal acquisition modules with high 24-bit resolution and sampling rates can acquire detailed measurement distinguishing subtle audio changes, while managing heavy bass, stereo, HiFi and other high-end signals (noise Level < 3µVrms and THD+N < 100dB). In addition, the modules are suitable for mechanical equipment monitoring applications in harsh environments, with high precision and dynamic measurement performance enabling accurate monitoring and measurement of activity such as, for example, power plant turbines to detect operational anomalies
Automated Testing Reduces Total Cost of Ownership
Benefiting from ADLINK’s high-performance dynamic signal acquisition modules, users can build an automated audio and vibration test system and save the cost of purchasing expensive equipment while meeting the demand for high-specification mobile phone testing. Software support aids in the upgrading of detection tasks automated testing without the need for self-developing testing programs. Complete hardware and software solutions improve testing quality and reduce testing time and cost.
Easy Sensor Connection Reduces Wiring Time
By integrating pre-conditioning circuit design and providing built-in independent excitation current source (2 to 4mA) for all input/output channels, ADLINK dynamic signal acquisition products can directly connect and drive integrated electronic piezoelectric (IEPE) sensors through the front panel, with no need for extra signal conditioning equipment and power cabling, speeding measurement tasks and reducing overall system costs.
Software Support Simplifies Program Development
ADLINK’s dynamic signal acquisition series offers rich SDKs such as LabVIEW™, MATLAB® and other third-party software tools to assist users in quickly designing their programs and applications, shrinking the verification cycle and accelerating time to market. ADLINK’s proprietary audio analysis software helps speedily complete audio testing of headphone jacks, microphones, speakers and other electro-acoustic components with no need for programming
