Description
The NI PXIe-4498 is a high-precision Dynamic Signal Acquisition (DSA) device designed to meet the needs of advanced noise, vibration, and harshness analysis, dynamic structural testing, and applications involving large microphone arrays. This device is identified by part numbers 780218-01 and 780218-02, categorizing it within the PXI DSA product line.
Boasting a 24-bit resolution, the PXIe-4498 provides exceptional data accuracy, ensuring that every nuance of the signal is captured. It supports a high sampling rate of 204.8kS/s (kilo-samples per second), enabling the analysis of high-frequency components of the signal. With 16 input channels, this device is well-suited for applications requiring multiple signal acquisitions simultaneously.
The device offers 4 gain settings, allowing users to optimize signal levels for precise measurements. Its AC-coupled signal input ensures that only the AC component of the signal is measured, filtering out any DC bias that could distort the analysis. The PXIe-4498 is enhanced with TEDS support (Transducer Electronic Data Sheet), which simplifies sensor setup and configuration by automatically loading sensor parameters.
Additional features include both analog and digital filters to improve signal quality by eliminating unwanted frequency components, and hardware triggering capabilities, which enable synchronized acquisition across multiple devices. The device supports various triggering modes, including a start trigger and a digital trigger compatible with 5 V TTL/CMOS, allowing for precise control over the timing of data acquisition.
