Description
The PXI-4495 is a state-of-the-art PXI Sound and Vibration Module designed to meet the needs of a wide range of sound and vibration analysis applications. It comes in two part numbers: the standard version is 780059-01, and the version that includes software is 780060-01.
This module boasts synchronous sampling across all input channels, ensuring precise data capture. The signal input is handled by a 24-bit mechanism capable of accommodating simple sources of input as well as IEPE constant current sources, making it highly versatile.
One of the standout features of the PXI-4495 is its built-in antialiasing filters, which automatically adjust to the sampling rate. This feature ensures that signal integrity is maintained, free from the distortions that can arise from aliasing.
Furthermore, the module offers software selectable input gains of up to 20 dB, allowing users to optimize the signal levels for best performance. The heart of the PXI-4495’s data acquisition system is a 24-bit delta-sigma Analog-to-Digital Converter (ADC), renowned for its high fidelity and precision.
For applications requiring customization, the module includes a Programmable Gain Amplifier, which can be set from 0 to +30 dB in 10 dB steps. This feature allows users to adjust the gain to match the requirements of their specific application, enhancing flexibility and performance.
The PXI-4495 also supports TEDS Class 1 smart sensors, enabling it to automatically read and write sensor information. This smart sensor support simplifies setup and configuration, enhancing usability. Additionally, the module offers IEPE support, with the ability to turn constant current on or off as selected in the accompanying software.
It is important to note that the PXI-4495 is designed to work with NI-DAQmx driver software, and it is not compatible with the Traditional NI-DAQ (Legacy) driver. This
