PXI-4462是一款專為聲音和振動(dòng)應(yīng)用而設(shè)計(jì)的模塊。它提供了四通道動(dòng)態(tài)信號(hào)采集，用于高精度的頻域測量，并具有六種增益設(shè)置來配置輸入范圍。此外，PXI-4462還具有軟件可配置的交流/直流耦合和IEPE調(diào)理功能。
PXI-4462具有多種功能和應(yīng)用場景。
首先，它支持兩個(gè)獨(dú)立的輸入通道，允許同時(shí)采集兩個(gè)聲音信號(hào)或振動(dòng)信號(hào)，這在需要進(jìn)行多通道數(shù)據(jù)采集和分析的場合非常有用。
其次，該模塊通常提供高分辨率的數(shù)據(jù)采集，以捕獲和分析細(xì)微的信號(hào)特征。這對于需要精確測量和分析聲音或振動(dòng)信號(hào)的應(yīng)用非常重要。
此外，PXI-4462還支持高采樣率，以確保準(zhǔn)確的信號(hào)還原和頻譜分析。這使得它在需要高頻采樣和頻譜分析的應(yīng)用中具有優(yōu)勢。
該模塊通常支持多種輸入源，包括麥克風(fēng)、加速度計(jì)、傳感器、振動(dòng)器等，以滿足不同應(yīng)用的需求。因此，它可以廣泛應(yīng)用于音頻測試、汽車噪聲和振動(dòng)分析、NVH（噪聲、振動(dòng)和粗糙度）分析等領(lǐng)域。
最后，PXI-4462通?？梢栽趯?shí)時(shí)或近實(shí)時(shí)條件下執(zhí)行信號(hào)分析，適用于實(shí)時(shí)監(jiān)測和實(shí)驗(yàn)。這使得它在需要實(shí)時(shí)數(shù)據(jù)采集和分析的場合非常有用。

PXI-4462

The PXI-4462 is a module specifically designed for sound and vibration applications. It provides four-channel dynamic signal acquisition for high-precision frequency-domain measurements and has six gain Settings to configure the input range. In addition, the PXI-4462 features software-configurable AC/DC coupling and IEPE conditioning.
The PXI-4462 has multiple functions and application scenarios.
First, it supports two independent input channels, allowing simultaneous acquisition of two sound or vibration signals, which is very useful in situations where multi-channel data acquisition and analysis is required.
Second, the module typically provides high-resolution data acquisition to capture and analyze subtle signal features. This is important for applications that require accurate measurement and analysis of sound or vibration signals.
In addition, the PXI-4462 supports high sampling rates to ensure accurate signal recovery and spectrum analysis. This makes it advantageous in applications that require high-frequency sampling and spectrum analysis.
The module typically supports multiple input sources, including microphones, accelerometers, sensors, vibrators, etc., to meet the needs of different applications. Therefore, it can be widely used in audio testing, automotive noise and vibration analysis, NVH (noise, vibration and roughness) analysis and other fields.
Finally, the PXI-4462 can generally perform signal analysis in real-time or near real-time conditions, making it suitable for real-time monitoring and experimentation. This makes it useful in situations where real-time data acquisition and analysis is required.
