Description
The National Instruments PXIe-4498 is a PXI Sound and Vibration Module, identified by part numbers 199108B-01L, also known as 780218-01 and 780218-02. This module falls within the category of PXI DSA and is designed to facilitate a broad range of applications, including Noise, Vibration, and Harshness Analysis, Dynamic Structural Test, and Large Microphone Arrays.
It features 16 channels that are simultaneously buffered, amplified, analog filtered, and sampled, ensuring high-quality data acquisition and processing. The 24-bit delta-sigma ADC resolution of this module ensures precise measurement capabilities, making it suitable for demanding applications that require accurate data analysis.
Moreover, it incorporates sophisticated digital filtering techniques, with the cutoff frequency automatically adjusting to the software-programmable sampling rate. This flexibility allows users to fine-tune their measurements according to specific requirements. Additionally, the PXIe-4498 employs both analog and digital filters in hardware for anti-aliasing, ensuring the integrity of the data captured.
Triggering options are versatile, supporting both analog and digital signal triggering. This includes two modes of operation and the capability to accept an External digital trigger (5 V TTL/CMOS-compatible), providing users with extensive flexibility in configuring their measurement setups.
