Description
The National Instruments PXIe-4464 model is a high-performance PXI Sound and Vibration Module designed for advanced sound and vibration applications. This module is renowned for its ability to provide precise measurements thanks to its 24-bit resolution and a maximum sampling rate of 204.8 kS/s per channel, ensuring high-quality data acquisition in demanding environments.
One of the key features of the PXIe-4464 is its capability for simultaneous sampling on all channels, which allows for synchronized data acquisition across multiple channels without the loss of fidelity or timing discrepancies. This feature is particularly important in applications requiring multi-channel sound and vibration analysis.
The module includes automatic adjustment of antialiasing filters, which significantly reduces the setup time and ensures optimal signal quality by preventing aliasing. Moreover, it offers six selectable input gain ranges, adjustable through software, providing flexibility in accommodating signals of varying amplitudes.
Another notable feature is the support for Transducer Electronic Data Sheet (TEDS), which simplifies the configuration of measurement systems by automatically identifying and loading the transducer’s characteristics. The built-in IEPE excitation circuit enables direct connection and powering of IEPE sensors, further enhancing the module’s versatility.
Each channel of the PXIe-4464 is equipped with a dedicated Analog-to-Digital Converter (ADC), ensuring accurate and isolated measurements. Users can also select from a range of digital filters to reject out-of-band noise, improving the signal-to-noise ratio for clearer analysis results.
The module supports various triggering configurations simultaneously, offering flexibility in synchronization and control of data acquisition processes. It is fully compatible with the NI-DAQmx driver software, which provides an intuitive interface for configuring and managing the module. Additionally, the Measurement & Automation Explorer (MAX) software further simplifies system configuration and setup.
With part numbers 783087-02 and 783087-01, the PXIe-4464 represents a blend of performance, versatility,
