ADLINK PCI-9527

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.

Applications

 

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.

Cost-effective Solutions for Audio Testing (5.71MB)

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

ADLINK PXES-2590 9-Slot PXI Express Chassis with Hybrid Slots

The ADLINK PXES-2590 is a 9-slot PXI Express chassis equipped with advanced features and functions. Compliant with PXI Express and cPCI Express specifications, the PXES-2590 offers one system slot, one system timing slot, and seven hybrid peripheral slots for versatile test and measurement applications requiring enhanced bandwidth. The hybrid-slot design accepts installation of CompactPCI, PXI, CompactPCI Express, and PXI Express modules into any peripheral slots in PXES-2590, maximizing flexibility. The PXES-2590 is built on a four-link PXI express chassis with 8 GB/s system bandwidth, and 1 GB/s slot bandwidth for all peripheral slots.

ADLINK PXI Express Chassis

The PXES-2590 is implemented with a smart system monitoring controller, reporting full chassis status, including fan speed, system voltages, and internal temperature. Equipped with an industrial grade AC power supply, the PXES-2590 still provides 400 W under 55°C, and delivers superior cooling capacity, from two 120 mm cooling fans on the rear of the chassis. Two BNC connectors for 10 MHz clock input/output on the rear panel increase chassis flexibility, enabling synchronization with supplementary devices.

PXES-2590 Backplane

Innovative Cooling MechanismPXES Cooling

The ADLINK PXES-2590 features an innovative heat dissipation solution. Two 185.9CFM cooling fans in the rear section of the chassis draw cool air through lower apertures, which is then exhausted through the back. This design generates uniform airflow for each PXI slot, delivering exceptional cooling.

When installed in a rack, the cooling design minimizes intake of hot air from the rear side, separating airflow for modules and power supplies, while isolating noise source (fan) from modules and maintaining a steady internal temperature.
