Description
The NI PXI-4462 PXI Sound and Vibration Module is a high-performance module designed for dynamic signal acquisition, carrying part numbers 779688-01 and 779131-01. This module falls under the category of PXI DSA (Dynamic Signal Acquisition), making it a specialized device for capturing high-quality sound and vibration data.
The PXI-4462 model boasts a 24-bit resolution, ensuring high-fidelity data capture, and supports a sample rate of up to 204.8 kS/s, allowing for precise and accurate measurement of fast transient events. It is equipped with four channels, enabling simultaneous acquisition from multiple sources.
Flexibility in signal capture is provided through six gain settings, alongside a high-pass filter with a cutoff frequency of 3.4 Hz, helping to eliminate low-frequency noise and improve signal quality. The module supports differential and pseudo-differential terminal configurations, offering versatility in connection types to suit a variety of sensors and signal sources.
For applications requiring high voltage tolerance, the PXI-4462 has an analog overload point of 10.7 Vpk at 0 dB gain range, safeguarding the module against signal overloads. It is compatible with NI-DAQmx driver software, facilitating easy integration and data capture within test systems.
The module is further compatible with a range of software including LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, Borland C++, and Microsoft .NET, ensuring flexible programming options for developers and engineers. Configuration and system integration are simplified through the Measurement & Automation Explorer (MAX) tool.
Though announced as obsolete by National Instruments, the PXI-4462 remains available for purchase and repairs through Apex Waves. Additionally, calibration services are available, with options for NIST accredited calibrations through a third party or basic in-house calibration, ensuring that the module maintains its precision and accuracy throughout its operational life.
