Description
The product described is the National Instruments PXI-4462 PXI Sound and Vibration Module. This device comes with part numbers 779688-01 and 779131-01, categorizing it under the PXI DSA category. Specifically, the model PXI-4462 is designed for high-quality sound and vibration measurements.
It boasts a 24-bit resolution, ensuring high precision in data acquisition. The sample rate of this module reaches up to 204.8 kS/s, capable of capturing fast-changing signals. Furthermore, it features a 4-channel dynamic signal acquisition, allowing for simultaneous recording from multiple sources. Users can benefit from its 6 gain settings to adjust the sensitivity of the module according to the signal levels.
An additional feature includes a high-pass filter with a cutoff frequency of 3.4 Hz, designed to eliminate low-frequency noise and unwanted signals. It supports differential and pseudo-differential terminal configurations, providing flexibility in connection setups. The analog overload point at a 0 dB gain range is 10.7 Vpk, indicating the maximum input signal level without distortion.
Compatibility with software is extensive, including LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, Borland C++, and Microsoft .NET. It operates with NI-DAQmx driver software, facilitating easy integration and use with various programming environments.
Although its obsolete status has been announced by National Instruments, it remains available for purchase and repairs through Apex Waves. Calibration services are available, including options accredited by NIST through a third party, ensuring the module’s accuracy and reliability in measurements.
