Description
The NI PXI-4496 is a high-performance, 24-bit Dynamic Signal Acquisition module designed for sound and vibration applications. With its part numbers 196150G-02L, 779748-01, 779748-02, this module falls under the category of PXI DSA and is specifically modelled as PXI-4496. The device boasts an impressive capability to sample data at a maximum rate of 204.8 kS/s, coupled with a dynamic range of up to 114 dB.
This module is equipped with 16 input channels, each capable of handling signals with a 24-bit resolution. These features make it an ideal choice for comprehensive sound and vibration analysis tasks. The PXI-4496 supports TEDS (Transducer Electronic Data Sheet) for easy transducer setup and comes with AC-coupled inputs. Additionally, it offers two gain settings to accommodate different signal levels.
For signal conditioning, the PXI-4496 uses IEPE constant current sourcing, which is suitable for powering Integrated Electronics Piezo-Electric (IEPE) sensors. The module utilizes delta-sigma modulation for its conversion technique, ensuring high fidelity in signal conversion.
Moreover, the PXI-4496 is equipped with both analog and digital antialiasing filters. These hardware-based filters are crucial for minimizing signal distortion and aliasing, thus ensuring the integrity and accuracy of the data acquired. This combination of features and capabilities makes the NI PXI-4496 a robust and versatile tool for professionals working in the field of sound and vibration analysis.
