ADLINK PCI-9527 for Audio Testing, Acoustic Measurement & Vibration Analysis Applications

ADLINK PCI-9527 24-Bit High-Resolution Dynamic Signal Acquisition and Generation Module

Audio Testing with the ADLINK PCI-9527

The PCI/PXI-9527 is a high-performance, 2-CH analog input and 2-CH analog output dynamic signal acquisition module. This module is specifically designed for audio testing, acoustic measurement, and vibration analysis applications.





The ADLINK PCI/PXI-9527 features two 24-bit simultaneous sampling analog input channels. The 24-bit sigma-delta ADC provides a sampling rate up to 432 kS/s at high resolutions, making it ideal for higher bandwidth dynamic signal measurements and audio testing. The sampling rate can be adjusted by setting the module DDS clock source to an appropriate frequency. All channels are sampled simultaneously and accept an input range from ±40 V to ±0.316 V. The PCI/PXI-9527 analog input supports software selectable AC or DC coupling and 4 mA bias current for integrated electronic piezoelectric (IEPE) sensors.

The ADLINK PCI/PXI-9527 also has two channels of 24-bit resolution, high fidelity analog output. The outputs occur simultaneously at software programmable rates up to 216 kS/s. A software programmable output range of ±0.1 V, ±1 V, and ±10 V is available on the output channels.

Dynamic Signal Acquisition Overview

Highly dynamic range measurement for audio signal analysis, audio testing, acoustic measurement and vibration monitoring continues to present challenges in the industry. To meet the needs of different applications, ADLINK announces the PXI-9527/PCI-9527, its high resolution 24-bit dynamic signal acquisition module with flexible input configuration and easy-to-use driver. The module provides analog input sampling rates up to 432KS/s and analog output update rates up to 216KS/s. The software selectable AC/DC coupling and IEPE current output also enable easy connection with multiple sensors.


Dynamic Signal Assistant (DSA):

ADLINK’s Dynamic Signal Assistant is a ready-to-run software utility designed for dynamic signal acquisition modules. A Windows®-based configuration interface for setting parameters is provided in addition to a real-time visualized data display. An instrument-style user interface is also provided for basic waveform generation. The Dynamic Signal Assistant can additionally log data from hardware modules. With the Dynamic Signal Assistant, signal acquisition and generation can be accomplished in just minutes, with no need for additional programming.




Acoustic Response Testing

Acoustic Response Testing
Historically, testing of acoustic response in audio playback devices has required critical performance analysis conducted by specialized audio engineers. In addition to design verification, acoustic response testing is also important in production line testing of multimedia devices.


Device Ausio Quality Testing

Device Audio Quality Testing
As multimedia devices in the marketplace increase in complexity and use, expectations for the quality of multimedia output have increased correspondingly, such that market leadership requires excellence of not only design and overall performance, but also output quality.


Noise, Vibration and Harshness

Noise, Vibration and Harshness
Beyond simply accommodating user comfort, monitoring and regulation of NVH can inform overall durability and may include analysis into the acoustic range. NVH management can be applied to cars, trucks and trains. Highly dynamic performance measurement facilitates accurate identification and analysis of noise sources.


Machine Condition Monitoring

Machine Condition Monitoring
Machine condition monitoring allows timely maintenance scheduling and preemptive action to avoid consequences of failure. ADLINK’s dynamic signal acquisition module provides flexible architecture for a wide variety of sensor input types.

The universal popularity of mobile devices presents potentially unprecedented growth for device makers. As the user base evolves, multimedia quality features increasingly as a major determinant in market dominance. Accordingly, integration of electro-acoustic components (i.e. receiver, speaker and microphone) into home use and industrial applications is becoming more of an industry mainstay every day. With audio quality thus recognized as a key consumer consideration, providers must maximize the effectiveness of audio testing in their manufacturing process.

This article discusses how high-resolution dynamic signal acquisition modules can serve as a low-cost replacement for existing sound cards while meeting all testing requirements for high-profile mobile devices
