Description
The part number 779687-01 refers to a PXI Sound and Vibration Module, specifically the model PXI-4461. This device falls under the category of PXI DSA, designed to cater to applications such as audio test, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring.
The PXI-4461 is a highly capable module featuring two-channel dynamic signal generation and acquisition. It offers a versatile input range design that allows users to choose from one of six gain settings, enhancing its adaptability to various signal levels. The module supports programmable AC/DC coupling, ensuring flexibility in accommodating different signal types.
Additionally, the PXI-4461 includes IEPE conditioning, making it suitable for interfacing with sensors that require constant current excitation and AC coupling. The terminal arrangements for AI (Analog Input) are designed to support both differential and pseudo-differential configurations, with a pseudo-differential resistance of 50 Ω between the BNC shell and chassis frame.
To ensure signal integrity, the module is equipped with digital filters to prevent aliasing, allowing for cleaner and more accurate measurements. Users can configure channels on a per-channel basis for differential and pseudo-differential modes, providing further customization for specific measurement requirements.
The PXI-4461 supports synchronization, allowing the acquisition clock to be synchronized with other devices for coordinated measurements across multiple channels or systems. It also offers versatile triggering options, including digital and analog triggers, for precise control over measurement timing.
With a 24-bit resolution, the PXI-4461 ensures high-fidelity data acquisition, enabling users to capture detailed and accurate measurements for thorough analysis and testing in a variety of applications.
