Description
The National Instruments PXIe-4464 is a high-performance PXI Dynamic Signal Analyzer that offers advanced features for sound and vibration applications. This module comes with part numbers 783087-02 and 783087-01, ensuring flexibility and compatibility for various setups. As a member of the PXI DSA category, it is designed to deliver precise measurements with its 24-bit resolution and a maximum sampling rate of 204.8 kS/s per channel.
One of the PXIe-4464’s notable features is its ability to perform simultaneous sampling on all channels, which is crucial for accurate, synchronized data acquisition in multi-channel systems. It offers six selectable input gain ranges, allowing users to adjust sensitivity according to the requirements of their specific applications. The device is equipped with built-in antialiasing filters that automatically adjust based on the sampling rate, ensuring optimal signal quality and preventing aliasing.
Additionally, the PXIe-4464 supports TEDS smart sensor integration, simplifying setup and configuration when using TEDS-enabled sensors. It also features a built-in IEPE excitation circuit, making it compatible with IEPE sensors without the need for external power sources. Each channel of the PXIe-4464 includes a dedicated Analog to Digital Converter (ADC), enabling true simultaneous sampling at maximum rates, which is essential for high-fidelity measurements.
The module offers sophisticated signal processing capabilities, including selectable digital filters for effective out-of-band noise rejection. This enhances the clarity and accuracy of measurements. For complex applications requiring precise timing and synchronization, the PXIe-4464 provides versatile triggering configurations that support simultaneous operations.
Software support comes in the form of NI-DAQmx, which includes the Measurement & Automation Explorer (MAX) for easy configuration and data management. This comprehensive driver support ensures a seamless integration and user experience, facilitating the development of advanced measurement and monitoring systems.
