Description
The NI PXI-4461 is a PXI Sound and Vibration Module, part number 779687-01, categorized under PXI DSA. This module is designed for precise and dynamic signal generation and acquisition, offering 2-channel capabilities. It provides users with one of six gain settings for the input range, ensuring flexibility in various testing scenarios.
Its coupling is programmable AC/DC, with incorporated IEPE conditioning for enhanced signal integrity. The PXI-4461 supports both differential and pseudo-differential terminal configurations for AI, and it ensures a resistance of 50 Ω between the outer BNC shell and chassis frame, minimizing interference and increasing accuracy.
For data integrity, digital filters are available to prevent aliasing, ensuring that signals are clean and reliable. The module utilizes 24-bit ADCs for high-resolution data acquisition. Sampling rates are software-programmable, including but not limited to 44.1 kS/s and 48.0 kS/s, giving users the flexibility to match the sampling rate to their specific application requirements.
Moreover, the acquisition clock of the PXI-4461 can be synchronized with other devices, facilitating coordinated measurements across multiple channels or devices. It supports both digital and analog triggering, allowing users to precisely control the timing of their measurements. The module’s design and features are tailored for comprehensive and accurate sound and vibration analysis, making it a valuable tool for a wide range of applications.
