Description
The PXIe-4464, manufactured by National Instruments, is a high-performance dynamic signal acquisition (DSA) module designed for sophisticated audio, vibration, and signal analysis in a PXI environment. This device is part of the PXI DSA category, and it is available with part numbers 783087-02 and 783087-01. It stands out for its remarkable precision and flexibility, making it an ideal solution for engineers and scientists who require accurate data acquisition and analysis.
The PXIe-4464 boasts a remarkable 24-bit resolution, ensuring high-fidelity signal acquisition and measurement accuracy. This module can reach a maximum sampling rate of 204.8 kS/s per channel, allowing for the capture of high-frequency signals without compromising data integrity. Users can select from six input gain ranges through software, providing versatility for a wide range of signal amplitudes.
A key feature of the PXIe-4464 is its built-in antialiasing filters, which are automatically adjustable to optimize performance across various measurement scenarios. These filters, along with the selectable digital filters for out-of-band noise rejection, ensure that the acquired data is free of unwanted noise and artifacts, enhancing measurement accuracy.
The module also supports TEDS smart sensor integration, simplifying setup and configuration by automatically identifying and loading sensor parameters. Additionally, the integrated IEPE excitation circuit facilitates direct connection to IEPE sensors, streamlining the measurement setup for accelerometers and microphones.
Each channel on the PXIe-4464 features its own analog to digital converter (ADC), enabling simultaneous sampling and ensuring precise synchronization across channels. This is particularly important for applications requiring phase matching or when measuring related signals concurrently.
For flexible and efficient data acquisition, the PXIe-4464 offers support for simultaneous triggering configurations, allowing users to precisely control the timing of their measurements. The device is fully compatible with NI-DAQmx driver software, which provides a comprehensive API for programming and automation. Additionally, the module can be configured and managed using National Instruments’ Measurement & Automation Explorer (MAX) software, further enhancing user experience and productivity.
