Description
The NI PXI-4495 is a high-performance PXI Dynamic Signal Analyzer (DSA) designed for high-channel-count sound and vibration applications. This device features a part number of 196150J-03L, with the standard model numbered 780059-01, and an alternative model, which includes the Sound and Vibration Measurement Suite Software, numbered 780060-01. As a member of the PXI DSA category, the PXI-4495 stands out for its capability to deliver precise measurements.
The PXI-4495 model offers 16 input channels with a sampling rate of up to 204.8 KS/s and a resolution of 24-Bit, ensuring high-fidelity data acquisition. This device is specifically designed to support applications that demand high-channel-count sound and vibration measurements, making it an ideal choice for engineers and researchers working in these fields.
Each of the 16 channels on the PXI-4495 can be configured with an input gain ranging from 0 to +30 dB in 10 dB steps, allowing users to optimize the signal-to-noise ratio for their specific measurement needs. The device is DC-Coupled, ensuring direct current components of the signal are retained for analysis. Moreover, it incorporates antialiasing filters that automatically adjust to the sampling rate, thereby ensuring the integrity of the measurements by reducing signal distortion.
From a software perspective, the PXI-4495 is supported by NI-DAQmx drivers, which are not compatible with Traditional NI-DAQ (Legacy) drivers, but offer a modern and efficient interface for device programming and data acquisition. The device boasts a range of software features including DAQ Assistant, programmable gain amplifier, TEDS Class 1 smart sensor support, and IEPE constant current support, which collectively enhance its versatility and ease of use in complex measurement setups.
In summary, the NI PXI-4495 is a robust and versatile DSA solution engineered to meet the demands of advanced sound
