Description
The PXI Sound and Vibration Module, identified by model PXI-4495, is an advanced measurement solution designed for comprehensive and precise sound and vibration analysis. This module is available in two part number options. The standard module is available under part number 780059-01, while the version that includes the Sound and Vibration Measurement Suite Software bears the part number 780060-01.
This module is a 24-bit, Integrated Electronics Piezo-Electric (IEPE) constant current signal module, ensuring high fidelity and accuracy in capturing sound and vibration signals. It supports synchronous sampling across all channels, allowing for simultaneous data acquisition without any signal delay or phase mismatch, ensuring integrity and reliability in the measurement process.
One of the key features of the PXI-4495 is its built-in antialiasing filters, which automatically adjust to the sampling rate. This feature is critical in preserving the quality of the signal by preventing aliasing, which can distort the measurement results. Furthermore, the module offers software selectable input gains of up to 20 dB, enabling it to adapt to a wide range of signal amplitudes from various sources.
The module operates with NI-DAQmx driver software, which is noted for its versatility and ease of use. However, it’s important to note that it is not compatible with Traditional NI-DAQ (Legacy), indicating a focus on newer technology and software standards.
Signal processing is another area where the PXI-4495 excels. Input signals are buffered, amplified, analog filtered, and digitized by a 24-bit delta-sigma Analog-to-Digital Converter (ADC) with digital filtering. This comprehensive processing path ensures that the signal is optimally prepared for analysis, minimizing noise and maximizing signal fidelity.
Additionally, the module features a programmable gain amplifier with a range of 0 to +30 dB in 10 dB steps, offering further flexibility in managing signal levels. Support for TEDS Class 1 smart sensors is also included, enabling the module to read and write to smart sensors, thus simplifying setup and calibration processes.
IEPE support is a critical feature for many sound and vibration measurement applications. The PXI-4495 allows for the constant current to be turned on or off as selected in software, accommodating both IEPE and non-IEPE sensors. This versatility makes the PXI-4495 a powerful
