NI PXI-4496 Sound and Vibration Module

The NI PXI-4496 Sound and Vibration Module is a high-performance data acquisition module for sound and vibration applications. The following are the main features and technical specifications of the module, which are organized as follows based on the reference articles provided:

Main Features

High-precision data acquisition: The PXI-4496 provides 16 24-bit analog inputs with a data acquisition rate of up to 204.8 kS/s (thousand samples per second) per channel, supporting high-precision sound and vibration data acquisition.

Large dynamic range: The module has a dynamic range of 114 dB and can handle sound and vibration signals of various amplitudes.

IEPE signal conditioning: The PXI-4496 supports IEPE (Integrated Electronics Piezo-Electric) constant current signal conditioning, which is suitable for use with sensors such as microphones and accelerometers.

Synchronous sampling: All channels can be sampled synchronously to ensure data consistency and accuracy.

Smart sensor support: Includes TEDS (Transducer Electronic Data Sheet) smart sensor support, which can automatically identify and configure sensor parameters.

Software configurable: Provides software-configurable AC/DC coupling, anti-aliasing filtering and other functions to meet different test needs.
