Signal acquisition module targets audio and vibration testing

The PCI-9527 is ADLINK Technology Inc.'s first 24-bit high-resolution dynamic signal acquisition module specifically designed for audio testing, acoustic measurement, and vibration analysis applications.

The PCI-9527 features two 24-bit simultaneous sampling analog input channels with a sampling rate up to 432 KS/s, two analog output channels with an update rate up to 216 KS/s, and one external digital trigger I/O connector.

It has a high dynamic input range of >100 dB, flexible input range from ±40 V to ±0.316 V, and analog inputs that support software-configurable features for AC or DC coupling and integrated electronic piezoelectric (IEPE) sensors to interface with an accelerometer sensor and microphone. Combining it all, the PCI-9527 offers the flexibility needed to create a  variety of automated test systems.

The PCI-9527 could be used in production testing for TVs, MP3 players, or other multimedia devices where high-quality sound needs to be guaranteed. The audio digitizer PCI-9527 can also be implemented in monitoring systems for mission-critical machinery, such as turbines in a power plant. Defects in the metal components of such turbines would generate abnormal sounds and vibration under operation, which would require high-dynamic range audio equipment to detect.

The PCI-9527 includes drivers and SDK support for mainstream Windows operating systems as well as third-party application including LabVIEW. ADLINK also provides Dynamic Signal Assistant APP Utility, an application for system integrators to perform validation and reduce overall design cycle time.
