Description
The National Instruments PXI-4495 is a PXI Sound and Vibration Module designed for high-fidelity data acquisition in sound and vibration analysis applications. This module is part of the PXI DSA (Dynamic Signal Analyzer) category, offering advanced features for accurate measurements.
It supports part numbers 198226A-01L, 780059-01 (Standard Module), and 780060-01 which includes the Sound and Vibration Measurement Suite Software, providing flexibility in application requirements.
The PXI-4495 features a 24-bit, IEPE (Integrated Electronics Piezo-Electric) constant current signal module, ensuring precise data collection from IEPE sensors. This module also boasts synchronous sampling across all channels, allowing for simultaneous data acquisition without phase discrepancy, ensuring data integrity and reliability.
Built-in antialiasing filters automatically adjust to the sampling rate, protecting against aliasing effects and preserving the fidelity of the measured signals. Users can select data gains up to 20 dB through software, enhancing the adaptability of the module to various signal levels.
For software integration, the PXI-4495 is compatible with NI-DAQmx, but it does not support Traditional NI-DAQ (Legacy), offering a modern software environment for data acquisition tasks. The module features a 24-bit delta-sigma ADC (Analog-to-Digital Converter), ensuring high-resolution data conversion.
The onboard Programmable Gain Amplifier can be adjusted from 0 to +30 dB in 10 dB steps, allowing for fine-tuning of the input signal gain to match the requirements of the measurement. Additionally, this module supports smart sensor compatibility, with the ability to read and write to TEDS Class 1 smart sensors, simplifying sensor management and configuration.
An option to turn the IEPE constant current on or off in software provides further flexibility, accommodating both IEPE and non-IEPE sensors, making the PXI-4495 a versatile choice for sound and vibration measurement applications.
