Description
<p>The <strong>National Instruments PXI-4461</strong> is a PXI Sound and Vibration Module that carries the part number <strong>188046A-01</strong>, which is also listed as <strong>779687-01</strong>. This device falls under the category of <strong>PXI DSA</strong> and is designed to offer high-quality sound and vibration data acquisition and generation.</p><p>With a <strong>two-channel dynamic signal generation</strong> and <strong>two-channel acquisition</strong>, the PXI-4461 is versatile and capable of handling complex sound and vibration analysis tasks. It features <strong>one of six gain settings</strong> for its input range design, allowing for optimized signal acquisition across various scenarios.</p>
<p>The module is equipped with <strong>programmable AC/DC coupling and IEPE conditioning</strong>, enhancing its flexibility and applicability in a wide range of environments and applications, including <strong>audio test, automotive NVH (Noise, Vibration, and Harshness), and machine condition monitoring</strong>. It supports both <strong>differential and pseudo-differential</strong> terminal arrangements for analog inputs, with a pseudo-differential resistance of <strong>50 Ω</strong> between the outer BNC shell and chassis frame, ensuring reliable signal integrity.</p>
<p>To prevent aliasing, the PXI-4461 incorporates <strong>digital filters</strong>, ensuring clean and accurate signal processing. Its channel configuration flexibility allows settings to be adjusted on a <strong>per channel basis</strong>, either in differential or pseudo-differential mode, accommodating a broad range of signal types and sources.</p>
<p>The module also supports <strong>acquisition clock synchronization</strong> with other devices, facilitating mixed-signal applications that require precise timing alignment across multiple data streams. Additionally, it offers both <strong>digital and analog triggering</
