Description
The PXI-4462 is a high-precision PXI Dynamic Signal Analyzer (DSA) designed for sound and vibration applications. It comes with the part numbers 779688-01 and 779131-01. This device falls under the category of PXI DSA, indicating its compatibility and design for the PXI platform.
With a 24-Bit resolution, the PXI-4462 offers exceptional data accuracy, making it suitable for detailed analysis. It supports a maximum sample rate of 204.8 kS/s, allowing users to capture high-frequency signals with precision. The device features 4 input channels, enabling simultaneous data acquisition from multiple sources.
The dynamic range (DR) of this model is 118 dB, which provides a wide measurement range from the smallest to the loudest signal without distortion or loss of detail. It is PXIe Ready, ensuring it can be used in both PXI and PXI Express chassis, offering flexibility in system configuration.
Its high-pass filter has a cutoff frequency of 3.4 Hz, effectively removing unwanted low-frequency noise from the signal. The PXI-4462 supports both differential and pseudo-differential terminal configurations for analog input, offering versatility in connecting various types of sensors and signals. The analog overload point at 0 dB gain range is 10.7 Vpk, protecting the device and the integrity of the data from voltage spikes.
Software compatibility is extensive, including NI-DAQmx, LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, Borland C++, and Microsoft .NET, allowing for flexible programming and integration into existing systems. Configuration and data management can be easily handled through the Measurement & Automation Explorer (MAX) tool.
The device’s obsolete status has been announced, suggesting that it is in the process of being phased out, but it remains a reliable choice for current applications. For calibration, there are options for NIST accredited calibrations through a third party or basic (unaccredited)
