Description
The National Instruments PXI-4496 PXI Sound and Vibration Module is an advanced piece of equipment designed for comprehensive sound and vibration measurements. It is available in two part numbers: 779748-01, which is the standard module, and 779748-02, which includes the additional Sound and Vibration Measurement Suite for enhanced functionality.
This module is equipped with 16 input channels, each offering a high-resolution of 24-bit to ensure detailed data capture. The signal conditioning is managed through IEPE constant current technology, accommodating various transducers with ease. With an impressive dynamic range of up to 114 dB, the NI PXI-4496 is capable of capturing a wide range of signals without compromising the quality of measurements. Additionally, the module boasts a maximum sampling rate of 204.8 kS/s per channel, allowing for high-speed data acquisition.
One of the key features of the NI PXI-4496 is its delta-sigma modulation A/D conversion technique, which provides excellent phase linearity while maintaining low noise and distortion levels. To ensure the integrity of the data, the module is equipped with antialiasing filters that automatically adjust their cutoff frequencies. These filters utilize both analog and digital components to effectively prevent aliasing from occurring, negating the need for external filtering solutions.
