Asia's largest supplier of data acquisition and PXI platform products-ADLINK launched the new PXI Express dynamic signal acquisition module-PXIe-9529. The PXIe-9529 supports 8-channel, 24-bit resolution and 192 kS / s simultaneous sampling, and has an excellent dynamic range performance of 108 dB. It is an ideal solution for high-density, high-channel quantity measurement applications. The PXIe-9529 provides an optimized AC coupling cutoff frequency, which can be as low as 0.5Hz to measure micro-vibration signals. Each input channel has a built-in 4mA excitation current to connect an integrated electronic piezoelectric (IEPE) sensor such as an accelerometer or microphone Applications such as condition monitoring, acoustic vibration roughness (NVH), and arrayed (Phased Array) audio data collection.
"The modular measurement system has the advantages of high accuracy and easy expansion. We understand that more and more customers related to sound and vibration measurement have begun to choose PXI and PXIe modular measurement systems as their application platforms." Ling Hua Wu Youqian, Senior Product Director of Technology Measurement and Automation Products Division, said. "Taking ADLINK's PXIe-9529 8-channel design with an 18-slot PXI Express chassis and controller as an example, it can easily expand 136 channels, while maintaining high-precision frequency and synchronous sampling between modules. The highly flexible design can greatly save the purchase cost of the detection system and improve the detection efficiency for customers. It provides a cost-effective solution for measurement applications that require a high number of channels, such as arrayed (Phased Array) audio data acquisition. "
Simultaneous multi-module sampling
ADLINK's PXIe-9529 provides a comprehensive synchronous sampling design for high-channel-count data acquisition applications. The built-in lock loop (PLL) allows multiple modules to be locked to an external reference clock signal at the same time, such as PXI_CLK10 or PXIe_CLK100 provided on the backplane of the PXI Express chassis, to ensure that each module is measured at the same time. The shape trigger can ensure that the synchronization drop between modules is less than 1 ns. In addition, taking the 1 kHz input signal as an example, the optimized circuit design of the PXIe-9529 can maintain the phase degree (One degree of phase match) between any two channels at a very low 0.01 degree, enabling accurate multi-module simultaneous sampling without drop. .
Flexible operating options
ADLINK PXIe-9529 provides positive and negative 10 volts and positive and negative 1 volt input range selection, software-selectable AC / DC coupling function, differential and pseudo-differential anti-noise input configuration options, and provides positive and negative up to ± 42.4V The overvoltage protection configuration of the input terminals of the direction and the negative direction, and the flexible operation options can assist the user to complete the system development more easily.
In terms of software support, ADLINK PXIe-9529 supports multiple operating systems, including Windows 8, Windows 7, Windows XP and Linux, and is compatible with third-party software such as LabVIEW ™ and MATLAB®. DSA (Dynamic Signal Assistant) software provided by ADLINK for free can help users to quickly complete the design and application of the program, shortening the time for system verification and product launch.
With the new PXIe-9529 dynamic signal acquisition module, it is recommended to use ADLINK PXES-2780 3U 18-slot full-mix PXI Express chassis. For more product information, please refer to ADLINK website: http: //PXI/index.php
