Description
The National Instruments PXIe-4464 is a high-performance PXI Dynamic Signal Analyzer (DSA) designed for advanced sound and vibration measurements. This model, identified by its part numbers 783087-02 and 783087-01, offers a robust set of features tailored for precise data acquisition and analysis.
It utilizes an mXLR connection type for secure and reliable connectivity. The device boasts a maximum sample rate of 204.8 kS/s per channel, ensuring high-resolution data capture. With a 24-bit resolution, the PXIe-4464 provides accurate and detailed measurement results.
One of the standout features of this device is its ability to perform simultaneous sampling on all input channels, enhancing its efficiency and data integrity. It offers six selectable input gain ranges, allowing users to adjust the sensitivity according to the requirements of their specific application. Furthermore, the device is equipped with built-in antialiasing filters, which automatically adjust based on the sampling rate to maintain the quality of the captured signal.
The PXIe-4464 also supports IEPE excitation circuit for improved data integrity, especially beneficial over long sensor cable runs and with high-power sensors. Additionally, TEDS smart sensor support is provided, enabling easy integration and configuration of smart sensors.
Each channel of the PXIe-4464 features its own Analog to Digital Converter (ADC), allowing for simultaneous sampling at the maximum rate without compromising data quality. Users can also select from various digital filters to reject out-of-band noise, further enhancing the signal quality. The device supports multiple triggering configurations, facilitating synchronized measurements across multiple channels or devices.
For software integration, the PXIe-4464 is compatible with the NI-DAQmx driver and Measurement & Automation Explorer (MAX), providing a comprehensive environment for data acquisition, signal analysis, and system control.
